Every Smart Switch and Dimmer Compared: Check Your Wiring First (2026)
By SmartHomeWorkflow Team · Last updated 2026-09-10
Every product page for a smart dimmer leads with the app. The thing that decides whether you can use one at all is inside the wall: whether your switch box has a neutral wire, whether the location is single-pole or 3-way, and what the LED load limit is. So this directory leads with the install reality, and the table renders live from the same sourced records behind our compatibility checker.
IKEA BILRESA Remote Control (Dual Button) — the catch, per ecosystem ~$6.99 at time of research — never treated as a live price
✓ Amazon Alexa: works — Basis is IKEA's blanket statement of compatibility with Matter systems from Amazon, Apple, Google, Homey and Samsung; IKEA publishes no per-ecosystem listing of which button actions (single, double, long press) each platform exposes. IKEA's own manual confirms the variability rather than resolving it: 'functionality depends on the type of product and the system it is connected to', and 'if the product is connected to another smart system that uses the Matter standard, check with the manufacturer for available features.' An on-page customer Q&A reports Alexa surfaces only single-press per button; that report is unverified against any official document.
✓ Google Home: works — IKEA's blanket Matter-systems statement naming Google; button-action depth per platform is not documented by IKEA, whose manual sends you to the other vendor for it ('check with the manufacturer for available features'). Thread border router on the Google side required.
✓ Apple Home: works — IKEA's blanket Matter-systems statement naming Apple; button-action depth per platform is not documented by IKEA, whose manual sends you to the other vendor for it ('check with the manufacturer for available features'). Thread border router on the Apple side required.
✓ SmartThings: works — IKEA's blanket Matter-systems statement naming Samsung; button-action depth per platform is not documented by IKEA, whose manual sends you to the other vendor for it ('check with the manufacturer for available features'). Thread border router on the Samsung side required.
✓ Home Assistant: works — IKEA does not name Home Assistant. The path is HA's official Matter integration (local push); the CSA cert types this device as a Matter Generic Switch (0x000F), and no IKEA-specific HA listing exists.
Connection: Thread · Matter · Hub for full use: Yes (Matter controller plus a Thread border router; IKEA's stated example is its DIRIGERA hub. Per IKEA's compatibility statement it works with Matter systems from Amazon, Apple, Google, Homey and Samsung through that platform's Thread border router. The 10-product limit is narrower than the product page suggests: IKEA's manual states 'a maximum of 10 smart products from IKEA can be controlled with one remote control by pairing directly' — ten IKEA products, by direct pairing, not ten devices of any brand through a hub.) · Works offline: Yes — the core function runs on the device or your home network

Aqara Wireless Mini Switch — the catch, per ecosystem ~$17.99 Price at the time of research, 2026-08-30, read from Aqara's own storefront as typed product data: $17.99, no crossed-out original price, in stock. Established rather than re-confirmed — this page carried no price at all before, because aqara.com/us is a marketing site that routes buyers to retailers and publishes no figure. No sale is running, so $17.99 is the regular price and not a discount that will lapse.
? Amazon Alexa: inconclusive — Not established, and the reason is Aqara's own two-step. Aqara's compatible-platforms page does list Alexa, Google Home, SmartThings, IFTTT, Matter and Home Assistant — under a blanket footnote, 'Hub may be required for certain ecosystems or functionalities' — but it then explicitly refuses to be read as a per-device answer: 'Note: Not all Aqara child devices are compatible with all platforms. Please see details for each device.' The details for THIS device turn out to be no list at all: its own product page carries no compatibility section, and the single platform it names anywhere is Apple, in a feature panel about the Apple Home app. So Aqara routes the question to a page that never answers it — which is different from a page that answers 'no'. Recording 'full' would use a catalogue-wide list Aqara says not to; recording 'none' would read a denial into a page that lists nothing. Unknown is the honest value, and this becomes answerable the moment Aqara publishes per-device platform detail.
? Google Home: inconclusive — Not established, on identical grounds to Alexa. Google Home appears on Aqara's catalogue-wide platforms page, which then says 'Please see details for each device' — and this device's own page publishes no compatibility list whatsoever, naming only Apple and only in a feature panel. There is no enumeration here to read Google's absence against. A Matter-bridging Aqara hub is the plausible route, but plausible is not documented, and a stateless button's individual press actions are exactly the kind of feature that survives bridging poorly.
✓ Apple Home: works — The only ecosystem Aqara claims for this switch, and it claims it clearly: the product page carries a single 'Works with Apple HomeKit' badge and states 'Aqara Hub is required to enable this product to work with HomeKit technology.' The Aqara hub bridges the Zigbee button into HomeKit; iOS 10.3 or later. Note the basis — this rests on Aqara's word alone, with no Apple document confirming what a Home app automation can do with the button's individual press actions.
? SmartThings: inconclusive — Not established, on identical grounds. SmartThings appears on the catalogue-wide platforms page and on no Aqara page specific to this switch. For sibling Aqara sensors the route is a Matter-bridging hub (M2 on current firmware, M3, M100 or G5 Pro) republishing the Zigbee device — but no first-party page applies that to this model, and a stateless button is not the same bridging case as a sensor.
◐ Home Assistant: partial — The route that skips Aqara hardware entirely: Zigbee2MQTT documents WXKG11LM against any generic Zigbee coordinator, so the button works with no Aqara hub at all. Two honest limits. It is a community integration Aqara does not endorse or document, which is why this is partial rather than full. And the button actions are not uniform across production runs — Zigbee2MQTT states that 'the triple, quadruple, hold and release is not supported by all versions of this device', with single and double click as the dependable pair. The alternative route, bridging through a Matter-capable Aqara hub, is not documented by Aqara for this model.
Connection: Zigbee · Hub for full use: Yes (Yes, and Aqara says it twice on the product page and again in the HomeKit line: 'An Aqara hub is required.' and 'Aqara Hub is required to enable this product to work with HomeKit technology.' This is a Zigbee device with no Matter or Thread radio of its own, so it never joins an ecosystem directly — the hub does that on its behalf, and which hub you buy is what decides how far the button reaches. Home Assistant users running their own Zigbee coordinator can skip Aqara hardware entirely, but that is a community route Aqara does not endorse.) · Works offline: Yes — the core function runs on the device or your home network

SONOFF iFan04-L Wi-Fi Ceiling Fan and Light Controller — the catch, per ecosystem ~$19.9 at time of research — read from SONOFF's own US store listing, which showed it as a 'Sale price' rather than a list price, so it is a promotional figure and not a stable one. Never treated as a live price.
✓ Amazon Alexa: works — SONOFF states it plainly on the product page — 'Works natively with Amazon Alexa and Google Home for hands-free voice control' — and repeats it in the product summary. Read the word 'natively' as SONOFF's marketing rather than as an architecture claim: the route is eWeLink account linking through SONOFF's cloud, so it depends on your internet and on eWeLink's service being up. SONOFF publishes no list of what Alexa can actually address, so whether fan speed steps and the light are separately controllable by voice is undocumented.
✓ Google Home: works — Named in the same sentence as Alexa and carrying the same qualification: cloud-routed through eWeLink, with no published command list. Google Home is also named a second time in SONOFF's Matter-bridge blurb, but that is the eWeLink CUBE route described in the Apple cell, not a separate integration.
? Apple Home: inconclusive — SONOFF advertises a route on this product's own page — 'Works With Apple Home Via Matter Bridge ... Seamlessly connect SONOFF WiFi devices to Matter via CUBE OS built-in Matter Bridge -- free, local, and ready for Apple Home, Google Home, Alexa, SmartThings, and Home Assistant' — and we leave this open because of what that sentence is actually about. Its subject is 'SONOFF WiFi devices' as a class, and neither SONOFF nor eWeLink publishes a list of which models the bridge really carries; eWeLink's own wording is 'many eWeLink-supported Wi-Fi devices', with 'many' doing real work. Two further things to know before treating this as an Apple Home product: eWeLink CUBE OS is separate software you have to run somewhere on your own network, not a feature of the controller, and what Apple Home connects to is a Matter BRIDGE rather than a Matter device — so what shows up in the Home app depends on what the bridge chooses to pass along. We leave it open rather than call it supported, because a statement about a whole product range is not evidence about this model.
? SmartThings: inconclusive — Same situation and same sentence as the Apple cell: SmartThings is named in SONOFF's eWeLink CUBE Matter-bridge blurb about 'SONOFF WiFi devices' generally, with no per-model support list on either side, and reaching it means running eWeLink's self-hosted CUBE OS. SONOFF publishes no SmartThings setup article for this controller and Samsung's own materials do not name it.
? Home Assistant: inconclusive — Not established, and the reason is worth reading before you buy. Home Assistant publishes no SONOFF or eWeLink integration of its own — the two pages such an integration would live at still do not exist, checked again on 19 September 2026 — so there is no official route from that side. The route the maker does advertise is its free eWeLink CUBE bridge, whose own page, re-read the same day, says it brings "many eWeLink-supported Wi-Fi devices, such as SONOFF products" into Matter for Apple Home, SmartThings, Google Home, Alexa and Home Assistant. That sentence is about a class of products with an open edge — many, such as — rather than about this fan and light controller, so it neither promises Home Assistant control nor rules it out. Community projects for SONOFF hardware exist outside Home Assistant's own documentation; we did not check their model lists ourselves, so we do not lean on them. We leave this open rather than call it a no, because a route is claimed and merely unconfirmed for this model, which is the opposite of a maker that names no route at all.

Zooz 800 Series Z-Wave Long Range Double Switch ZEN30 800LR (Light & Fan Combo) — the catch, per ecosystem ~$24.95 $24.95 for new stock, read 2026-09-20, against a $44.95 regular price the seller still shows. That is down from the previous $34.95, corrected from what this record carried as of 2026-08-21, and the drop is why the date beside the number matters. ⚠ The source is an authorised Zooz retailer rather than Zooz itself — Zooz's own product page publishes no price at all — so this is a seller's figure rather than the manufacturer's, and it is marked as such on the page. ⚠ Read it alongside the availability picture, which has moved: in August every purchase condition on that listing — new, open box, refurbished and used — was showing sold out, and on 2026-09-20 new was the only condition in stock. The other three are still sold out and two of them are priced above new anyway: open box $30.95, refurbished $26.95, used $20.95. Availability on this listing has swung once and can swing back, so check it before planning around the number.
? Amazon Alexa: inconclusive — Not established, and deliberately not converted into a 'no'. Neither Zooz's own page nor the retailer listing mentions Alexa anywhere — notable, because Zooz DID take the trouble to enumerate ten compatible controllers, so its silence on voice assistants is a more considered silence than most. But the architecture still forbids reading it as absence: Alexa reaches a Z-Wave device through the hub, and several controllers on Zooz's own compatible list carry Alexa bridges. Whether it works is therefore a question about your controller that Zooz has not answered and cannot. Unknown on both sides.
? Google Home: inconclusive — Not established, for exactly the same reason as Alexa and stated rather than cross-referenced: Google is named on neither page, Zooz's compatibility list covers hubs rather than voice assistants, and a Z-Wave switch's Google support is supplied by the controller. Several hubs Zooz names do offer Google integrations. The honest state is unknown on both sides, and a buyer who needs Google specifically should check their intended hub's device support rather than this product's page.
? Apple Home: inconclusive — Not established. Apple, HomeKit and Siri appear on neither page. As with the two voice assistants, that silence is weak evidence for a Z-Wave device whose platform reach is inherited from its controller — and Zooz's compatible list includes controllers that expose devices to Apple Home. What it does NOT include is any Apple-native route: there is no Matter here, no Thread, and no direct pairing, so any Apple answer would arrive through a hub doing translation. Unknown rather than none, but a buyer wanting Apple Home should treat this as a hub-shopping question and verify before buying.
◐ SmartThings: partial — Named by Zooz itself in its list of compatible controllers, which is better evidence than most SmartThings cells in this catalogue get — the other Z-Wave fan control verified the same day left this cell unknown precisely because its vendor said nothing. Rated 'partial' rather than 'full' for a reason that applies to every platform on a Z-Wave device: what SmartThings can actually DO with the switch is decided by SmartThings' own device handling, not by Zooz, and neither side publishes a capability list for this model. A two-load device is exactly where that matters — whether SmartThings exposes the fan and the light as two independent controls or collapses them is unestablished. Transport is unknown because it depends on the SmartThings hub generation and configuration rather than on this product.
✓ Home Assistant: works — ⊕ The strongest answer on this page, and unusually it is supported from BOTH sides rather than only from Home Assistant's. Zooz names Home Assistant directly in its own compatible-controller list, specifying 'Z-Wave JS/JS UI' — vendors here very rarely acknowledge Home Assistant at all, and two of the three products checked alongside this one named it nowhere. From the other side, Home Assistant's official Z-Wave integration 'allows you to control a Z-Wave network from Home Assistant via the Z-Wave JS driver', works over your own network with nothing in anyone's cloud, and runs a Z-Wave server and adapter on your own hardware. Rated full on that pairing. ⚠ Two costs stated so the rating is not read as frictionless: this route needs a Z-Wave adapter plugged into the Home Assistant machine, and Home Assistant's own page defers device support to the Z-Wave JS device database rather than naming models, so this exact model is covered as a certified Z-Wave device by class — the 800LR being a recent revision makes checking that database the sensible step before you buy.
Connection: Z-Wave · Hub for full use: Yes (Yes, and Zooz's channel states it without hedging: 'Z-Wave gateway controller required - sold separately.' This is a Z-Wave device — it does not join your Wi-Fi and it does not talk to your router. Without a controller it is a wall switch with no smart behaviour whatsoever, and the controller usually costs more than the switch. ⚠ The other requirement is wiring, and the warning published alongside it is the most useful sentence on the whole listing because it names the specific way people get this wrong: 'Check for neutral connections BEFORE you buy. A white wire from a 14-3 romex is usually NOT a neutral.' A white wire is the thing a non-electrician assumes is a neutral, and in a switch loop it frequently is not. Open the box and identify the conductors before ordering. One functional constraint that shapes what the device can do: 'You'll always need a separate wire to control another load from this device' — this is a double switch driving two loads, so both loads have to be wired to it. Physically it is accommodating: 'With a very slim profile of just over 1 inch and pigtail connections, the device is a breeze to install in almost any switch box.') · Works offline: Not checked — we have not established whether this keeps working without the internet
GE Cync Paddle Dimmer Smart Switch (Matter) — the catch, per ecosystem ~$25.99 at time of research — never treated as a live price. Corrected 2026-08-08 from a rounded 26 to the published 25.99.
✓ Amazon Alexa: works — Two real paths: Matter (local, no account — but on/off/dim only) or the cloud-linked Cync Alexa skill; the WiFi path is not 'direct', it requires the Cync app and account linking. Schedules, scenes, and advanced dimming config stay in the Cync app either way; legacy non-Matter Cync switches have only the cloud-skill path.
✓ Google Home: works — Two real paths: Matter (local, on/off/dim only) or Cync-account cloud linking in Google Home — GE's guide requires signing into the Cync account, so the WiFi path is cloud-linked, not direct. No deeper Google-specific integration exists for the switches; app features stay in the Cync app.
✓ Apple Home: works — Matter only, and only on the 2025+ SKUs — legacy Cync switches have no Apple Home path
✓ SmartThings: works — Via Matter on the 2025+ Matter-generation SKUs only — GE's SmartThings support is Matter-only, so legacy WiFi/Bluetooth Cync switches have no SmartThings path at all.
✓ Home Assistant: works — Local via HA's Matter integration; an official cloud Cync integration also exists (HA 2025.10+, one app session at a time)

Philips Hue Smart Button — the catch, per ecosystem ~$32.99 at time of research (philips-hue.com US product page) — never treated as a live price
? Amazon Alexa: inconclusive — Not established, and the gap is Signify's. This SKU's specification block does list 'Compatibility with 3rd party systems: Alexa, Google Home, Apple Home, IFTTT, Klikaanklikuit, Matter, Samsung Smartthings, Sonos' — but that field appears across Hue's catalogue and describes what the Hue SYSTEM connects to, not what this button does inside those systems. No Hue document we could find states whether a button press can trigger an Alexa routine or touch a non-Hue device: the smart-button setup guide names no third-party platform at all, and Hue's Matter guide says the Bridge 'Supports all Hue products' without addressing accessories. Asserting a level from a system-wide boilerplate list is exactly the kind of sweeping claim that is easier to write than to defend.
? Google Home: inconclusive — Not established, on identical grounds to Alexa: Google Home appears in this SKU's system-level third-party list, and in no Hue document that describes what the button itself can do outside the Hue app.
? Apple Home: inconclusive — Not established. Apple Home is in the SKU's system-level compatibility list, but Hue's own Apple Home page discusses bulbs and lights and does not address whether accessories such as the smart button, dimmer switch or tap dial are exposed to the Home app. Since the whole value of a button in Apple Home is triggering non-Hue accessories, an unverified 'yes' here would be the misleading answer.
? SmartThings: inconclusive — Not established, and the page we can point at does not settle it. Hue's Apple Home page is a single-platform marketing page — it explains what Hue lights do inside Apple Home and never lists platforms at all, so it says nothing about SmartThings by design rather than by omission. Elsewhere, Samsung SmartThings does appear in this product's system-level compatibility field, but that field runs across Hue's whole catalogue and describes what the Hue SYSTEM connects to, not what this particular button does once you are inside another app. Hue's Matter guide mentions SmartThings only in passing, for multi-admin control, and addresses bulbs rather than accessories. The specific question — what a Hue smart button can actually do from inside SmartThings — is one nobody has published an answer to.
✓ Home Assistant: works — The one platform that documents what the button actually does is Home Assistant, not Hue. A Hue Bridge is required. Home Assistant's official Hue integration treats the button as a device with no on/off state of its own: each press sends an event you can use to trigger an automation, and the battery level shows up as a sensor. Presses reach Home Assistant locally, as they happen, on a V2 Bridge. One documented limit worth knowing before you build a double-press automation: Home Assistant's documentation says Hue limits each device to one event per second.
Connection: Zigbee · Bluetooth · Hub for full use: Yes (No for the basic job, yes for anything interesting. Without a Hue Bridge the button pairs directly to bulbs — Signify's setup guide is specific about the ritual: 'Hold the smart button up to the light you want to control. Stay within six inches of the light. Press and hold the smart button for three seconds until the green light starts to blink', repeated for 'up to 10 bulbs'. ⚠ Signify does not say which radio carries that pairing, and we do not guess: its Bluetooth explainer describes Bluetooth as the phone-to-bulb path and lists accessory-to-bulb pairing as a separate method that works 'without using the Bridge or app'. With a Bridge the button reaches up to 50 lights and, critically, becomes configurable: 'A Hue bridge is required to be able to change the way a Hue dimmer switch, smart button, or tap dial switch controls your lights.' So the Bridge is what turns a fixed on-off button into a scene cycler, dimmer or automation trigger.) · Works offline: Yes — the core function runs on the device or your home network

✓ Google Home: works — Listed as 'Hey Google' in Leviton's spec sheet.

Inovelli Blue Series Smart Fan/Light Canopy Module (VZM36) — the catch, per ecosystem ~$55 at time of research (Inovelli's own store) — never treated as a live price
◐ Amazon Alexa: partial — Only via an Amazon Echo model containing a built-in Zigbee radio, which acts as the hub. Inovelli lists 'Amazon Echo (requires compatible version)' but publishes no dedicated Alexa setup article, so feature depth is undocumented.
✗ Google Home: doesn't work — Absent from Inovelli's published platform compatibility list and from its help centre, and the module carries no radio Google Home can reach. Recorded as none on the basis of a curated manufacturer list that omits it, not an affirmative 'not supported' statement.
✗ Apple Home: doesn't work — Absent from Inovelli's published platform list, no setup documentation exists, and the device carries no Matter or HomeKit radio. Recorded as none on the basis of a curated manufacturer list that omits it, not an affirmative statement.
✓ SmartThings: works — Requires a SmartThings hub with a Zigbee radio; Inovelli publishes a dedicated setup article.
✓ Home Assistant: works — Inovelli publishes setup articles for both ZHA and Zigbee2MQTT; requires a Zigbee coordinator.
Connection: Zigbee · Hub for full use: Yes (Yes, a Zigbee hub is required for smart control. One nuance: Inovelli documents direct Zigbee binding between a Blue Series wall switch (VZM31-SN or VZM35-SN) and this module, which it describes as near-instantaneous and able to operate without the hub once configured — but a Zigbee coordinator is still needed to perform the initial pairing and binding.

✗ Google Home: doesn't work — Google is listed as not compatible on Inovelli's Hub Platform Compatibility Chart; Google Home hardware has no supported path to this Zigbee switch.
✗ Apple Home: doesn't work — Apple is listed as not compatible on Inovelli's Hub Platform Compatibility Chart; there is no documented Apple Home path, native or bridged.

Inovelli White Series Smart Fan/Light Canopy Module (VTM36) — the catch, per ecosystem ~$60 at time of research (Inovelli's own store) — never treated as a live price
✗ Amazon Alexa: doesn't work — Inovelli says so itself, on the page selling the module: 'Not compatible with Amazon Echo as their platform does not support the Matter Fan profile at this time.' The blocker is on Amazon's side, not the module's — a Matter fan device type that Alexa does not yet implement — so it could change without any hardware change. Note that Inovelli's own help-centre manual lists 'Amazon Alexa' in its platform sentence; the two Inovelli surfaces disagree and the disagreement is published below.
✓ Google Home: works — Listed by Inovelli as 'Google Home (with compatible device)' — the compatible device being a Google speaker or display that acts as a Thread border router and Matter controller. Inovelli does not publish which fan features Google exposes, and the basis for this cell is Inovelli's own list rather than a Google source.
✓ Apple Home: works — Listed by Inovelli as 'Apple (with compatible device)'. A HomePod or Apple TV with a Thread radio is needed as border router and Matter controller. As with the other ecosystem cells here, the basis is Inovelli's compatibility list, not an Apple document, and feature depth is not published by either party.
✓ SmartThings: works — Listed by Inovelli as 'SmartThings (with compatible device)' — a SmartThings hub with Thread, acting as border router and Matter controller. Inovelli does not publish per-feature detail, and the basis is Inovelli's own list.
✓ Home Assistant: works — Inovelli lists Home Assistant and annotates it 'requires Thread Border Router'. Home Assistant's own Matter integration is official and local push, and this device is CSA-certified Matter 1.2, so both parties document the path. Hubitat is also listed by Inovelli, excluding the C-4.
Connection: Thread · Matter · Hub for full use: Yes (Yes. Inovelli states it plainly: 'This module requires a hub that supports Thread.' In practice that means a Thread border router on the network plus a Matter controller for whichever ecosystem you use — Inovelli's own compatibility list annotates Home Assistant and Hubitat with 'requires Thread Border Router' explicitly, and the manual gives the radio budget as up to 100 metres line-of-sight between the module and the closest border router.) · Works offline: Yes — the core function runs on the device or your home network

Fanimation fanSync AC Motor WiFi Receiver (WFR50) — the catch, per ecosystem
✓ Amazon Alexa: works — Fanimation documents the link in its own app guide and instruction sheet — 'Link with Amazon Echo, Google Home and IFTTT', performed inside the fanSync WiFi app under Settings > Connections — and points to Amazon's own help article for the account-linking step. Two limits worth knowing before you buy for voice: the route is an account link through Fanimation's cloud, so it stops when your internet does, and Fanimation publishes no list of what Alexa can actually say to the fan, so speed steps, direction and light behaviour through voice are undocumented.
✓ Google Home: works — The same sentence and the same Connections menu name Google Home alongside Amazon Echo, with Fanimation linking to Google's own account-linking help page. Same two limits as the Alexa cell: cloud-routed, and no published command list.
✗ Apple Home: doesn't work — Apple Home, HomeKit and Siri appear nowhere in any of Fanimation's three own documents for this product. That absence is evidenced rather than guessed at: the app guide devotes a titled section to the question 'How do I link my fanSync WiFi control with Amazon Echo, Google Home and IFTTT?', lists the Connections menu, then goes further and names the platforms you can reach indirectly — 'In order to connect with NEST, ECOBEE, Samsung Smart things, wink, etc. ... you must connect via IFTTT.' Apple is in neither list, direct or indirect. We record this as a no on the strength of a maker describing its whole control surface and leaving Apple out of it, not on an outright 'not supported' statement — which Fanimation does not make. The reason sits in the hardware as well as the paperwork: the receiver only speaks Wi-Fi, to Fanimation's own cloud service, and Fanimation names no HomeKit or Matter support anywhere, so Apple Home has nothing to connect to.
◐ SmartThings: partial — Reachable, but only the long way round, and Fanimation says so itself: 'In order to connect with NEST, ECOBEE, Samsung Smart things, wink, etc. ... you must connect via IFTTT.' That means the fan is not a SmartThings device — it is a fanSync device that IFTTT can pass commands to, so it does not appear in SmartThings as a fan with speed control, automations route through a third company's service, and IFTTT's own account tiers govern how many of them you can run and how fast they fire. That is why we call it partial rather than supported. Fanimation publishes no SmartThings setup article, and Samsung's own materials do not name this product.
✗ Home Assistant: doesn't work — Home Assistant publishes no Fanimation or fanSync integration, and Fanimation names Home Assistant nowhere in its own materials — so there is no supported route from either side. The nearest documented workaround is the IFTTT relay described under SmartThings, which is not a Home Assistant integration and gives you no local control. We record this as a no rather than as unknown because we checked it properly: neither of the two pages such an integration would live at exists, and we separately searched Home Assistant's complete list of integrations for both brand names and found nothing.

Hubbell iDevices Z-Wave Enabled Radio Frequency (RF) Decorator Fan Control (IDEVZ07W) — the catch, per ecosystem
◐ Amazon Alexa: partial — Named by Hubbell on its own product page — 'Conveniently operated through other smart home integrations with Alexa, Alarm.com, and the Google Assistant' — with the mechanism stated in the specification as 'Compatible with Amazon Alexa and Google Home via Hub'. Recorded 'partial' rather than 'full' for a specific and important reason: the support is not this switch's, it is inherited from whatever Z-Wave hub you buy. Hubbell names no hub, publishes no command set, and cannot promise behaviour it does not control — two households running this switch on different controllers will get different Alexa experiences, and one running it on a hub with no Alexa bridge will get none at all. Transport is recorded cloud because that is what a hub-to-Alexa link ordinarily is, though the specific path depends on the hub.
◐ Google Home: partial — Named by Hubbell as 'the Google Assistant', with the same 'via Hub' qualification as Alexa. Rated 'partial' for the identical reason and it is worth stating rather than cross-referencing: this is a capability of the Z-Wave controller you choose, not of the switch. Hubbell publishes no command set and names no specific hub, so what Google can actually do with the fan — set a speed, or only switch it — is determined downstream of this product entirely.
? Apple Home: inconclusive — Not established, and deliberately not converted into a 'no' despite the vendor's silence. Hubbell names Alexa, Alarm.com and Google Assistant and mentions Apple, HomeKit and Siri nowhere. But the architecture is exactly the reason silence cannot be read as absence here: this is a Z-Wave device whose platform reach is supplied by the hub, and several Z-Wave controllers do expose their devices to Apple Home. Whether that works for this switch depends on a controller Hubbell does not name and did not test. Unknown on both sides is the honest state — this is the same reasoning applied to the SmartThings cell.
? SmartThings: inconclusive — Not established. Hubbell does not mention SmartThings, and no Samsung documentation naming this model was located. As with Apple, vendor silence is weak evidence for a Z-Wave device: SmartThings hubs include Z-Wave radios and pair certified Z-Wave devices routinely, so the plausible answer is 'probably, via the hub' — but 'probably' is not a record. Unknown on both sides, and a buyer who needs SmartThings specifically should confirm against the SmartThings device list rather than against this page.
✓ Home Assistant: works — The strongest cell on this record, and it comes entirely from the other side — Hubbell names Home Assistant nowhere. Home Assistant's official Z-Wave integration 'allows you to control a Z-Wave network from Home Assistant via the Z-Wave JS driver', IoT class 'Local Push', running a Z-Wave server and adapter on your own hardware with no cloud in the path. That makes this one of the few control routes for this switch that touches no vendor service at all. Rated 'full' on a device-CLASS match rather than a model list: Home Assistant supports Z-Wave networks generally and points to the Z-Wave JS device database rather than enumerating models on its page, so this specific product is covered as a certified Z-Wave device rather than by name — and that is the claim on this cell most exposed to the device database proving to lack a configuration file for it. ⚠ One real cost to state: this route requires buying a Z-Wave adapter (Home Assistant names its own Connect ZWA-2 as an example) and plugging it into the machine running Home Assistant. That is hardware, not just a setting.
Connection: Z-Wave · Hub for full use: Yes (Yes, unavoidably, and Hubbell says so in the same breath as the platforms: 'Compatible with Amazon Alexa and Google Home via Hub'. This is a Z-Wave Plus certified device, and Z-Wave is not Wi-Fi — it does not talk to your router, it talks to a Z-Wave controller, and without one the switch is a wall control with no smart function at all. That controller is a separate purchase and this catalogue's other Z-Wave records show the range of what qualifies: a dedicated hub, a Home Assistant machine with a Z-Wave adapter, a SmartThings hub, or a security panel like Alarm.com's. ⚠ Read the name carefully, because it describes an architecture people miss: this is a 'Radio Frequency (RF) Decorator Fan Control'. The wall switch speaks Z-Wave to your hub AND radio frequency to the fan's own receiver — so the fan itself must be one this control can drive. Hubbell's stated compatibility is by motor type rather than by brand: 'Works with most Shaded pole and split capacitor driven motors'. That is a specification about your ceiling fan, not about your smart home, and it is the one to check first. Electrical ratings published: 2.5 A at 120 V. Hubbell does not state a neutral-wire requirement anywhere on the page, which is an omission rather than a 'no' — verify against the installation instructions before buying.) · Works offline: Yes — the core function runs on the device or your home network

Leviton Decora Smart Wi-Fi Dimmer, 2nd Gen (D26HD) — the catch, per ecosystem
✓ Amazon Alexa: works — Cloud skill via My Leviton account; Leviton states existing cloud integrations are not impacted by the Matter update, so both paths can coexist.
✓ Google Home: works — Cloud integration via My Leviton account; Matter is an alternative path.
✓ Apple Home: works — Native HomeKit on stock firmware. Installing the Matter firmware removes the existing HomeKit connection; the dimmer must be re-added to Apple Home with its Matter pairing code from the My Leviton app.
✓ SmartThings: works — Listed by Leviton among supported ecosystems; cloud-linked, with Matter as an alternative path.
◐ Home Assistant: partial — No official Leviton integration. The community decora_wifi integration is cloud-polling, flagged legacy, and does not list the D26HD. The documented route is the Matter firmware plus Home Assistant's Matter integration.

Leviton Decora Smart Wi-Fi Switch, 15A (D315S) — the catch, per ecosystem
◐ Amazon Alexa: partial — Leviton documents two ways in, and the one recorded here is the one that costs you nothing extra. Its own instruction sheet says you can 'set up your device with My Leviton and link your Amazon account, or you can use Matter to set it up directly in the Amazon Alexa app if you have a compatible Matter-enabled Amazon device'. The account-linked route needs only the free app, which is why it is the one recorded; the Matter route keeps the traffic on your own network, but only if you already own an Echo that speaks Matter, and buying one to get there is a real cost rather than a detail. This is still recorded as partial, and the reason has changed — worth knowing if you read this page before. It is no longer that we could not tell how the switch reaches Alexa; Leviton now says, in its own instructions. What is missing is the other half of the evidence this catalogue wants before calling a platform claim settled: a statement from Amazon's own side that this specific model works, and Amazon publishes no product list we are able to read.
◐ Google Home: partial — The same two routes as Alexa, and it stops at partial for the same reason. Leviton's instruction sheet: 'you can set up your device with My Leviton and link your Google account, or you can use Matter to set it up directly in the Google Home app if you have a compatible Matter-enabled Google device.' The account-linked route is the one recorded, because it needs no hardware you do not already have; the Matter route needs a Google speaker or display that speaks Matter. Google publishes no product directory we can check for this model, so as with Alexa the maker's half of the evidence is now documented and the platform's half still is not.
✓ Apple Home: works — Coded differently from Alexa/Google deliberately, and the asymmetry is reasoned rather than arbitrary: Apple Home speaks only HomeKit or Matter, and Leviton documents NO native-HomeKit path for this model — unlike the 2nd-Gen line, which advertised HomeKit prominently. The instruction sheet carries no HomeKit branding at all and its single controller step is 'Connect to a Matter controller (optional)', while the product page says 'Matter ready out of the box'. Matter is therefore the only remaining path, not a guess. Full because on/off is this device's entire function and its certified Matter device type is On/Off Light (0x0100). Platform requirement, not a D315S spec: Leviton states that controlling Matter accessories from the Apple Home app and Siri 'requires an Apple Home hub such as a HomePod or Apple TV running the latest software', and that the Matter pairing code lives in the My Leviton app under Device Settings.
◐ SmartThings: partial — Matter is the only route Leviton documents here, and it needs a hub you may not own. The instruction sheet is specific: 'For use with Samsung SmartThings, use Matter to set up your device in the SmartThings app and connect to a compatible Matter-enabled SmartThings Hub.' That makes SmartThings different from Alexa and Google on this switch — for those two Leviton offers an account-linking route that needs no extra hardware, and for SmartThings it offers none at all. So if you do not already have a Matter-capable SmartThings hub, there is no documented way in without buying one. That is a platform requirement rather than something this switch lacks, the same way Apple Home needs a HomePod or Apple TV here. Recorded as partial because Samsung's own side has not been checked for this model: the route Leviton publishes is clear, and confirmation from Samsung is the half still missing.
◐ Home Assistant: partial — Worth a note because makers rarely do this: Leviton lists Home Assistant by name on the product page ('Works with Matter, Amazon Alexa, Google Home, Apple Home, Smart Things, Home Assistant, Sonos, Resideo and more'). But it is the weakest of the five claims on this record: Home Assistant appears only on that marketing page and is absent from the installation instructions' own list, and no mechanism is documented. Home Assistant's existing community Leviton integration works through Leviton's cloud, is flagged as legacy, and predates this model entirely, so it cannot be assumed to cover it. Matter is the plausible route but is not stated for this pairing.

Lutron Caseta Diva Smart Dimmer (DVRF-6L) — the catch, per ecosystem
✓ Amazon Alexa: works — Works through the Caséta Smart Hub, which is required and sold separately — this dimmer speaks Lutron's proprietary Clear Connect RF and has no radio of its own. With the hub, Amazon Alexa does the whole job: on, off, dim and scenes by voice. Lutron names Amazon Alexa for the Caséta SYSTEM on its 'Works With' page and publishes no per-model list, so the level rests on that page plus this record's own evidence that the dimmer is part of that system.
✓ Google Home: works — Works through the Caséta Smart Hub, which is required and sold separately — this dimmer speaks Lutron's proprietary Clear Connect RF and has no radio of its own. With the hub, Google Home does the whole job: on, off, dim and scenes by voice. Lutron names Google Home for the Caséta SYSTEM on its 'Works With' page and publishes no per-model list, so the level rests on that page plus this record's own evidence that the dimmer is part of that system.
✓ Apple Home: works — Apple Home support is a function of the Caseta Smart Hub; no hub, no Home app or Siri.
✓ SmartThings: works — Official Lutron-SmartThings integration; requires a Lutron Smart Hub plus at least one Lutron device (Lutron support + casetawireless.com SmartThings pages).
✓ Home Assistant: works — Official built-in integration (lutron_caseta), local push, but it connects to the Smart Hub, never to the dimmer directly.
Connection: Clear Connect · Hub for full use: Yes (Caseta Smart Hub (L-BDG2-WH) or Smart Hub PRO is required for app control, scheduling, scenes, and every ecosystem integration (Alexa, Google Home, Apple Home, SmartThings, Home Assistant). Without a hub it still works as a normal wall dimmer: slider at the wall, wired 3-way, and up to 10 directly paired Pico remotes. Hub price is not published on an official Lutron page.) · Works offline: Yes — the core function runs on the device or your home network
Lutron Caséta Smart Fan Speed Control Switch (PD-FSQN) — the catch, per ecosystem
✓ Amazon Alexa: works — Requires a Lutron Smart Hub; the switch itself has no standard radio.
✓ Google Home: works — Requires a Lutron Smart Hub; the switch itself has no standard radio.
✓ Apple Home: works — Lutron states the Smart Hub contains Apple Home technology — the hub provides it, not the switch.
✓ SmartThings: works — Requires a Lutron Smart Hub plus a SmartThings account. Caseta scenes cannot be imported into SmartThings.
✓ Home Assistant: works — Official lutron_caseta integration with local push; fan speed control is an explicitly supported device type and appears as a fan entity. Requires a Smart Hub or Bridge PRO plus generated certificates. Note Lutron does not list Home Assistant on its own works-with page — support is documented only from the Home Assistant side.
Connection: Clear Connect · Hub for full use: Yes (Yes for anything smart. The switch carries only Lutron's proprietary Clear Connect RF and no standard radio, so every ecosystem integration happens at the hub. It works as a manual wall control with no hub and pairs directly with Pico remotes and Caseta motion sensors (up to 10 devices), but the Lutron app, remote access, voice assistants, and all platform integrations require a Lutron Smart Hub or Smart Hub PRO.

Lutron Caséta Wireless In-Wall Switch (PD-5ANS) — the catch, per ecosystem
✓ Amazon Alexa: works — A property of the Lutron Smart Bridge rather than of this switch, which carries no standard radio of any kind. 'Amazon Alexa' is named on Lutron's Caséta 'Works With' page, which is a system-level page: it lists what the Caséta system works with, not what each SKU does. Same framing as the Claro and PD-5WS-DV records.
✓ Google Home: works — Named on the same Lutron 'Works With' page as 'Google Assistant', which is the voice service rather than the Google Home app. Reached through the Smart Bridge; the switch itself is Clear Connect only.
✓ Apple Home: works — 'Apple Home' is named on Lutron's 'Works With' page, alongside 'Apple Watch' as a separate entry. The Apple Home technology sits in the Lutron hub, not in the switch.
✓ SmartThings: works — 'Samsung SmartThings' is named on Lutron's 'Works With' page. Reached through the Smart Bridge and a SmartThings account. A system-level limitation the Claro record notes applies here too: Caséta scenes cannot be imported into SmartThings.
✓ Home Assistant: works — The one platform answer on this page that Lutron does not claim and Home Assistant does — which is the stronger of the two directions. Home Assistant's own Caséta integration documents support for the line, names the specific bridges it works with, runs over your own network rather than through anyone's servers, and states plainly that it handles 'Wall switches as switches', which is exactly what Lutron classifies this model as. Home Assistant appears nowhere on Lutron's 'Works With' page, so the support is documented from one side only — and that side is the one doing the integrating.
Connection: Clear Connect · Hub for full use: Yes (Yes for anything a buyer would call smart. The switch speaks Lutron's proprietary Clear Connect RF and carries no Wi-Fi, Bluetooth, Zigbee, Z-Wave or Thread radio, so the app - and with it every ecosystem on this record - arrives only with a Lutron Smart Bridge or Smart Bridge PRO. Without one it still works as a wall switch and pairs with Pico remote controls, which is what Lutron's own wiring diagrams for this model describe: it publishes '3-Way or Multilocation Wiring with a Pico Remote' alongside 'Single Pole Wiring' and '3-Way Wiring with a Mechanical Switch'. Lutron's installation page for this SKU carries a 'Do I need a Smart Hub?' section, which is a fair summary of the decision. There is also a range limit that comes with that radio: the switch has to sit within 60 ft (18 m) line-of-sight, or 30 ft (9 m) through walls, of the hub, a repeater, or the Pico remote it answers to.) · Works offline: Yes — the core function runs on the device or your home network

✓ SmartThings: works — 'Samsung SmartThings' is named on Lutron's 'Works With' page. Reached through the Smart Bridge and a SmartThings account. The Claro record notes a limitation that applies to the system rather than to any one switch: Caséta scenes cannot be imported into SmartThings.
✓ Home Assistant: works — The one platform on this page that Lutron does not claim and the other side does, which is the stronger of the two directions. Home Assistant's own Lutron Caséta integration documents support for the Caséta line, names the specific bridges it works with, controls them over your own network, and states plainly that it handles "Wall switches as switches" — which is exactly what this model is. Home Assistant appears nowhere on Lutron's "Works With" page, so the support is documented from one side only, and that side is the one doing the integrating.
Connection: Clear Connect · Hub for full use: Yes (Yes for anything that resembles a smart switch, and the specification submittal is unusually precise about the boundary. Without a hub the PD-5WS-DV is still a wireless switch in a narrow sense: it works with Pico remote controls, with Caséta motion sensors, and with Lutron Radio Powr Savr occupancy and vacancy sensors 'in standalone applications', and Lutron notes those sensors 'do not work with Smart Bridge or Smart Bridge PRO'. The app, and with it every ecosystem on this record, arrives only with a hub - the feature table lists 'Works with the Lutron app (via a Smart Bridge or Smart Bridge PRO)' as a distinct line, footnoted 'The Lutron App is required for setup and use with the Smart Bridge and Smart Bridge PRO.' There is a distance constraint too, which most hub dependencies do not state: the switch 'must be located within 60 ft (18 m) line-of-sight or 30 ft (9 m) through walls of a Lutron Smart Bridge, Smart Bridge PRO, or Caséta Wireless Repeater.') · Works offline: Yes — the core function runs on the device or your home network

Lutron Pico Wireless Remote Control — the catch, per ecosystem
✗ Amazon Alexa: doesn't work — The Pico controls your Lutron devices; it does not appear to Alexa as anything. Lutron's integration model exposes load controllers only — dimmers, switches, fan controls, smart plugs and hybrid keypads — and Lutron states affirmatively that Pico remotes are not devices in the Apple Home app and do not show up in the SmartThings app. Lutron publishes no equivalent sentence for Alexa specifically, so this cell rests on that stated model plus the two affirmative statements about sibling platforms, not on an Alexa-specific disclaimer. Practical effect: a Pico press cannot start an Alexa routine or touch a non-Lutron device.
✗ Google Home: doesn't work — Same as Alexa, and on the same basis. Lutron's Google Home FAQ discusses controlling Lutron scenes by voice, not surfacing Pico remotes to Google — and the same load-controllers-only model applies. Recorded as none from Lutron's stated integration model rather than from a Google-specific statement, which Lutron does not publish.
✗ Apple Home: doesn't work — Lutron states it directly: 'Lutron Smart Hubs, Repeaters, Processors, Pico remote controls, and standard keypads are not controllable devices via the Home app.' Only load controllers appear. A Caséta Smart Hub (L-BDG2 or L-BDGPRO2) is what gives the SYSTEM its HomeKit connection — it does not put the Pico in Apple Home.
✗ SmartThings: doesn't work — Lutron's own FAQ answers the question outright: 'Do Pico remotes show up in the SmartThings app? No, Pico remotes do not show up in the SmartThings app.' The Lutron devices a Pico controls can appear; the remote itself cannot.
✓ Home Assistant: works — The one platform where a Pico press escapes Lutron's walls. Home Assistant's official Lutron Caséta integration exposes 'Pico Remotes as device triggers', and its documentation states 'Device triggers are available for every button on Pico remotes, Shade remotes, and keypads' — press, release, multi-tap, and long-press on HomeWorks QSX. That makes a $20 button a trigger for anything Home Assistant controls. It is local push, and it requires one of the named bridges: the Caséta Smart Hub (L-BDG2-WH), Smart Bridge PRO (L-BDGPRO2-WH), RA2 Select Main Repeater, RadioRA 3 processor or QSX processor.
Connection: Clear Connect · Hub for full use: Yes (A Lutron system is required, but a hub is not always. Lutron states that a Pico can be paired straight to a Caseta device: 'Although it is not required for functionality between a Pico remote and a Caséta device, adding the Caséta Smart Hub to your system unlocks additional programming options.' So the remote works hub-free as an extra point of control for a switch, dimmer, fan control or shade you already own — and needs the Caséta Smart Hub only for scenes, schedules and any third-party integration. What it never does is work alone: there is no Pico-only mode, and it speaks only to Lutron equipment.) · Works offline: Yes — the core function runs on the device or your home network
TP-Link Kasa Smart Ceiling Fan Control and Dimmer Switch (KS240) — the catch, per ecosystem
✓ Amazon Alexa: works — Named by TP-Link on the product page as one of the platforms the switch integrates with. Cloud transport, since a Wi-Fi switch with no hub reaches a voice assistant through TP-Link's service. What is not published is the command set — whether fan speed is settable by voice as a percentage or only on and off, and whether the light dims by voice, are questions the page does not answer, so 'full' here means the platform is supported rather than that every function has been documented as reachable. That gap matters more than usual on a two-load device, because there are two things to address and one switch.
✓ Google Home: works — Named by TP-Link on the product page as Google Assistant. Cloud transport for the same architectural reason as Alexa. The same undocumented-depth caveat applies and is worth repeating rather than cross-referencing: TP-Link publishes no command list, so how granularly voice can set fan speed versus simply switching it, and whether the light's dimming level is voice-addressable, are not established.
✓ Apple Home: works — A real Apple Home answer, and it is worth saying so explicitly because two other products verified this same week turned out to offer only Siri Shortcuts dressed up as Apple support. TP-Link's own words describe the Home app rather than a voice phrase: 'Easily integrate your KS240 with Apple Home to conveniently manage your connected fans and lights using the Apple Home App or with voice commands by asking Siri.' A device you manage in the Apple Home App is a device in Apple Home — a tile, a room, something automations can address and the household can share. TP-Link also uses Apple's current name for the platform rather than the retired 'HomeKit' branding. One thing NOT published: TP-Link does not say whether the route is HomeKit or Matter, so the mechanism is recorded as native and local on the strength of the Home-app statement rather than a stated protocol. Matter is named nowhere on the page.
✗ SmartThings: doesn't work — Plan on a different switch if SmartThings runs your house. TP-Link's specification sheet for the KS240 has a line headed 'Third-Party Platform', and the whole of it reads Apple Home, Alexa, Google Assistant. SmartThings is not on it, and that line is where TP-Link says what a switch works with. This is not the company ignoring SmartThings generally: the same line on TP-Link's own Tapo S505 switch does carry Samsung SmartThings, so TP-Link adds it where it applies, and for this fan-and-light switch it did not. Apple Home, Alexa or Google Home are the three that are stood behind here.
✓ Home Assistant: works — ⊕ The strongest cell on this record, and unusually so because it rests on a MODEL NAME rather than a device class. Home Assistant ships an official TP-Link Smart Home integration, IoT class 'Local Polling', which 'allows you to control your TP-Link Kasa Smart Home Devices and TP-Link Tapo Devices' — and its supported-wall-switch list names KS240 explicitly, alongside HS200, HS210, HS220, KS200, KS200M, KS205, KS220, KS220M, KS225 and KS230. Most integration cells in this catalogue rest on a class match that a future model list could narrow; this one is already at model granularity. The integration covers fans and lights among its device categories, which matters for a two-load switch. ⚠ One condition attached to this model specifically: Home Assistant footnotes KS240 as requiring authentication, so expect to supply TP-Link account credentials during setup even though the control path itself is local. TP-Link names Home Assistant nowhere — the whole cell comes from the other side.
Connection: Wi-Fi · Hub for full use: Yes (No hub, and TP-Link names none anywhere on the page — this is a Wi-Fi switch that talks to your router directly. What it does require is wiring, and one requirement is absolute and stated twice: 'Neutral Wire Required: Yes', with the installation note 'Neutral wire is required. Connect wires to the smart switch as below.' That is the single fact that decides whether you can buy this, and it is decided by your house rather than by you — older US switch boxes frequently have no neutral, and no setting or adapter works around it. Check the box before ordering. The switch replaces a combined fan-and-light wall control, so it is a two-load device in one gang: it sets fan speed and dims the light from the same faceplate.) · Works offline: Not checked — we have not established whether this keeps working without the internet

TP-Link Tapo S505 Smart Wi-Fi Light Switch — the catch, per ecosystem
✓ Amazon Alexa: works — Named in TP-Link's compatibility list as 'Alexa' and as a commissioning route - the Alexa app is one of the Matter-compatible apps TP-Link names for setup. Same Matter mechanism as the other three cells.
✓ Google Home: works — TP-Link writes 'Google Assistant' in its compatibility list, which is the voice service, while naming the 'Google Home app' as the commissioning route - the app rather than the assistant. Both belong to the same Matter path; the wording is TP-Link's own inconsistency and does not change the mechanism.
✓ Apple Home: works — 'Apple Home' is named in TP-Link's compatibility list, and the mechanism is stated rather than implied: the switch is Matter-certified and TP-Link tells buyers to commission it 'by scanning the included code with any Matter-compatible app, such as the Alexa app, Google Home app, and Apple Home app'. Transport is recorded local because a Matter-over-Wi-Fi device is controlled on the local network by the ecosystem's own controller, not through a TP-Link cloud. TP-Link separately names 'Apple Siri' among the voice assistants.
✓ SmartThings: works — 'Samsung SmartThings' is named in TP-Link's compatibility list. Unlike the other three, TP-Link does not name a SmartThings commissioning app, so the platform is claimed without a route being described - the Matter path is the reasonable reading, and it is the only mechanism this switch has.
? Home Assistant: inconclusive — TP-Link does not name Home Assistant for this product. Its compatibility list reads 'Matter-Certified, Apple Home, Alexa, Google Assistant, Samsung SmartThings' and stops there, and the setup copy names three Matter-compatible apps without including one for Home Assistant. That list does not rule Home Assistant out, and the reason is the first thing on it: 'Matter-Certified' is not a platform but a certification, which is TP-Link saying the switch answers to Matter controllers as a class rather than only to the four it goes on to name. A list that opens with an open class has not told you what is missing from it. Stated so a reader is not misled by our own caution: Home Assistant operates its own Matter integration and does not need a vendor's blessing, so the practical answer may well be yes - but that would be this catalogue reasoning from the protocol rather than reporting a claim either party has made about this switch, and the two are not the same thing.
Connection: Matter · Wi-Fi · Hub for full use: Yes (No, and that is the practical difference between this switch and the Lutron alternative in the same subcategory. The S505 joins the house Wi-Fi directly and commissions into an ecosystem over Matter: TP-Link's own instruction is that 'Users can also set up Tapo S505 by scanning the included code with any Matter-compatible app, such as the Alexa app, Google Home app, and Apple Home app', with Bluetooth used for onboarding through TP-Link's own app instead. A Tapo Hub exists and is optional, needed only to bring other Tapo hardware into the picture: TP-Link states 'When working with smart sensors, the Tapo Hub is required' and 'When working with a Tapo Smart Button, the Tapo Hub is required'. Neither is needed to switch a light.) · Works offline: Yes — the core function runs on the device or your home network

The neutral-wire question
Two products here work without a neutral, and they get there differently. The Lutron Caseta Diva needs no neutral and no workaround parts; that is the point of Lutron’s proprietary Clear Connect radio, and the trade is that every smart feature routes through the separately sold Caseta Smart Hub. The Inovelli Blue 2-1 ($60) does it on open Zigbee, but a no-neutral install requires a bypass device at the fixture, and Inovelli’s own docs warn about flicker and reboots on low-wattage loads without one.
The rest require a neutral, stated plainly in their own documentation: the Cync paddle dimmer ($25.99, and note its Matter refresh dropped the old no-neutral trick), the Kasa KS225, and the Leviton D26HD, which Leviton has discontinued. Pre-1980s wiring rules these out at many switch boxes.
What each one needs besides wiring
The hub column of this category is quieter than the sensor category’s, but it exists. Lutron requires its hub for anything smart. Inovelli requires a Zigbee hub, and the officially supported list is narrow: SmartThings, Hubitat, Home Assistant, Homey, and Zigbee-radio Echo models. Inovelli’s compatibility chart lists Apple Home, Google Home, and the Hue Bridge as not compatible, which surprises people who assume any Zigbee device rides any Zigbee hub. Cync, Kasa, and Leviton connect straight to 2.4 GHz WiFi with no hub, though Apple Home support on the Kasa runs through Matter and therefore needs a HomePod or Apple TV in the house.
The IKEA BILRESA ($6.99) is the odd one in the table on purpose: it switches things without touching your wiring at all. It is a battery-powered two-button Matter controller from IKEA’s 2025 Matter wave, and per IKEA it works with any Matter ecosystem, not just the DIRIGERA hub. The requirement it does carry: a Thread border router must already be on your network before a phone or ecosystem can see it. It can also skip all of that and pair straight to IKEA smart products — up to ten of them, IKEA’s own, by direct pairing. Batteries are sold separately; IKEA’s manual puts a fresh pair of AAAs at about 24 months.
Two catches the spec sheets underplay
Single-pole versus 3-way. The Kasa KS225’s datasheet says it plainly: not compatible with 3-way wiring. If two switches control your hallway light, that dimmer is out for that location. Lutron handles 3-way with a Pico remote or accessory switch; Inovelli and Leviton use their own companion hardware rather than standard traveler wiring.
Matter that arrives by firmware can break what works today. The Leviton D26HD is discontinued (its successor is the D36HD), yet it received a Matter certification in February 2025 via an opt-in firmware program. The catch, per Leviton’s own support pages: installing the Matter firmware severs an existing Apple HomeKit pairing, and the switch must be re-added over Matter, automations and all. Upgrade on your schedule, not on a whim.
Where to start
Open the switch box before you open your wallet. Neutral present and a single-pole location: the Cync and Kasa are the low-cost WiFi paths, with the Cync covering all five ecosystems. No neutral: Lutron if you want it to just work behind its hub, Inovelli if you already run Home Assistant, Hubitat, or SmartThings and don’t need Apple or Google. No desire to rewire anything: the BILRESA rides an existing Thread border router for $6.99. Then run your exact combination through the checker, or start from your ecosystem with the starter quiz.
Frequently asked questions
How do I know if my switch box has a neutral wire?
Turn off the breaker, remove the wallplate, and look for a bundle of white wires, usually capped together at the back of the box. Homes wired from the 1980s onward mostly have one at the switch; older homes often do not. When in doubt, an electrician can confirm in minutes, and it is worth confirming before you buy, not after.
Which smart dimmers work without a neutral wire?
In our library, two paths: the Lutron Caseta Diva needs no neutral and no extra parts by design, and the Inovelli Blue 2-1 supports no-neutral installs if you add a bypass device at the light fixture. The Cync, Kasa, and Leviton dimmers all require a neutral.
Do smart switches work with smart bulbs?
They solve different problems and usually should not share a circuit: a dimmer varies power to the fixture, which most smart bulbs handle poorly. Pick the layer that fits the fixture. Bulbs and strips live in our lighting directory; the wall hardware lives here.
What does the question mark in the table mean?
It marks a case we checked and official documentation does not answer. We record 'unknown' rather than guessing in either direction.
