5 Smart Plugs Compared: Lock-In, Matter, and the Wemo Lesson (2026)

IKEA GRILLPLATS Smart Plug — the catch, per ecosystem ~$7.99 at time of research — never treated as a live price

• ✓ Amazon Alexa: works — No Alexa-specific listing exists; coverage rests on IKEA's blanket statement of compatibility with smart systems from Amazon, Apple, Google, Homey and Samsung, via standard Matter with a Thread border router on that platform.
• ✓ Google Home: works — Same basis: IKEA's blanket Matter-systems statement naming Google; no Google-specific listing. Thread border router on the Google side required.
• ✓ Apple Home: works — Same basis: IKEA's blanket Matter-systems statement naming Apple; no Apple-specific listing. Thread border router on the Apple side required.
• ✓ SmartThings: works — Same basis: IKEA's blanket Matter-systems statement naming Samsung; no SmartThings-specific listing. 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), which supports certified Matter devices generically; there is no IKEA-specific listing on either side.

Connection: Thread · Matter · Hub for full use: Yes (Matter controller plus a Thread border router before phone or app control works. IKEA's stated example is its DIRIGERA hub; per IKEA's compatibility statement, equivalent Matter systems from Amazon, Apple, Google, Homey and Samsung apply, using that platform's own Thread border router. There is a hub-free path, but it excludes the hub path rather than supplementing it: IKEA's manual states the plug 'can be either paired directly to each other or connected to the IKEA Home smart system or any other system that uses the Matter standard. Only one connection method can be used at a time.' Direct pairing tops out at 'a maximum of 10 plugs from IKEA… with one remote control or motion sensor'.) · Works offline: Yes — the core function runs on the device or your home network

TP-Link Tapo P125M Mini Smart Wi-Fi Plug (Matter) — the catch, per ecosystem ~$11.99 at time of research — never treated as a live price

• ✓ Amazon Alexa: works — Matter path requires a Matter-capable Echo as controller (TP-Link FAQ 3564); the native Tapo-app-plus-Alexa path is also officially supported.
• ✓ Google Home: works — Matter path requires a Google Matter hub (Nest Hub, Nest Wifi Pro, or Google TV Streamer per TP-Link FAQ 3564); the native Tapo path is also officially supported.
• ✓ Apple Home: works — Apple Home works only via Matter. On iOS 18 or later an iPhone can add and locally control the plug with no home hub; a HomePod, HomePod mini, or Apple TV is still required for remote access, automations, and sharing (Apple support 102135; TP-Link FAQ 3564).
• ✓ SmartThings: works — Requires a SmartThings hub with Matter controller support (e.g., Aeotec SmartThings Hub, per TP-Link FAQ 3564). TP-Link lists SmartThings on the official product page.
• ✓ Home Assistant: works — TP-Link does not list Home Assistant; support comes from standard Matter via HA's official Matter integration. No Thread border router needed for WiFi Matter devices.

Connection: Matter · Wi-Fi · Hub for full use: No — verified that none is needed · Works offline: Yes — the core function runs on the device or your home network

THIRDREALITY Smart Plug Gen2 (Power Metering) — the catch, per ecosystem ~$12.99 thirdreality.com listed the single-pack at $12.99 and the four-pack at $38.99 on 2026-08-14. Neither was a discount: the 'compare at' price shown for each was the same as the selling price. Price at time of research.

• ◐ Amazon Alexa: partial — 🔴 THE FEATURE IN THE PRODUCT'S NAME IS NOT AVAILABLE ON EVERY HUB THE SAME PAGE CALLS COMPATIBLE. Alexa hosting works and is easy — pair to an Echo with a built-in Zigbee hub and 'just plug the Smart Plug in the wall outlet and say "Alexa, discover my devices"'. But the vendor scopes the energy monitoring separately: 'This function supported by Home Assistant, SmartThings, Hubitat and THIRDREALITY smart hub Gen2' — Echo devices are not in that list. So an Alexa-hosted buyer gets a switch, not a power meter. Recorded partial for exactly that reason.
• ◐ Google Home: partial — There is no direct Google route — this is a Zigbee device with no radio Google speaks. The vendor names two indirect paths: a hub that itself works with Google ('other ZigBee hubs that can work with Alexa or Google Home'), or its own bridge — 'Enabled by Smart Bridge MZ1 (Sold Separately), integrates with Apple HomeKit, Google Home, Amazon Alexa (Smart Speaker required) and SmartThings'. Either way the reach depends on the intermediary, and the energy-monitoring limitation above still applies unless that intermediary is one of the four hubs named for it.
• ◐ Apple Home: partial — Apple Home is reachable but only through a separately-sold box: 'Enabled by Smart Bridge MZ1 (Sold Separately), integrates with Apple HomeKit, Google Home, Amazon Alexa (Smart Speaker required) and SmartThings.' The MZ1 is $29.99 on the vendor's own storefront — more than twice the price of the plug — which is the number that decides whether this is a cheap Apple Home plug or an expensive one. ⚠ Worth knowing before generalising: the vendor names NO Apple route for its Smart Presence Sensor R2, so this bridge path is stated per product rather than brand-wide.
• ✓ SmartThings: works — One of the four platforms the vendor names for the full feature set, energy monitoring included: 'This function supported by Home Assistant, SmartThings, Hubitat and THIRDREALITY smart hub Gen2.' Requires a SmartThings hub with a Zigbee radio — the vendor names the 2015 and 2018 hub generations and Aeotec's.
• ✓ Home Assistant: works — The vendor documents this platform in the most detail, and is specific about which stacks: energy monitoring is supported on Home Assistant, and the restore-after-power-loss setting is scoped tighter still — 'Currently THIRDREALITY Hub Gen2 and Home Assistant (ZHA and ZigBee2MQTT) support this function.' A standard Zigbee device on a local coordinator, with no vendor cloud in the path.

Connection: Zigbee · Hub for full use: Yes (A Zigbee hub or coordinator is REQUIRED — the vendor says so in the product title itself ('ZigBee Hub Required'). It names the ones it works with: 'Echo (4th Gen), Echo Plus (1st Gen and 2nd Gen), Echo Studio, Eero 6, Eero Pro 6, Home Assistant, SmartThings 2015/2018, Aeotec, Hubitat and THIRDREALITY Hub'. Which hub you pick decides which FEATURES you get — see the catch.) · Works offline: Not checked — we have not established whether this keeps working without the internet

Amazon Smart Plug — the catch, per ecosystem ~$24.99 $24.99 is Amazon's own published price, unchanged from the launch release; Amazon's retail listing is not a page we can re-read, so treat this as a list price rather than what you would pay today

• ✓ Amazon Alexa: works — This is the only supported path. Voice control additionally requires an Alexa device (Echo, Fire TV, Fire Tablet) or the Alexa app.
• ✗ Google Home: doesn't work — Amazon's spec sheet: 'Amazon Smart Plug is optimized for simple setup and exclusive use with Alexa. Amazon Smart Plug does not support other voice assistants or smart hubs.'
• ✗ Apple Home: doesn't work — Excluded by the same official statement; no HomeKit or Matter path exists.
• ✗ SmartThings: doesn't work — Excluded by the same official statement ('does not support other voice assistants or smart hubs').
• ✗ Home Assistant: doesn't work — No official route exists. Amazon publishes no way for other software to control this plug — not over your own network and not through its cloud — and the plug's spec sheet rules out other smart hubs.

Connection: Wi-Fi · Hub for full use: No — verified that none is needed · Works offline: Not checked — we have not established whether this keeps working without the internet

Meross Smart Outdoor Plug (MSS620BHK) — the catch, per ecosystem ~$25.99 price at time of research (2026-08-09) on Meross's own US store, shown as a sale price against a $29.99 regular price — and read from a listing that was OUT OF STOCK on that date, so it is the price Meross asks rather than a price anyone could pay that day

• ✓ Amazon Alexa: works — Works through Meross's cloud-to-cloud skill, with each of the two sockets addressable by voice separately. Being cloud-routed, it stops working when your internet does — unlike the Apple Home path.
• ✓ Google Home: works — Cloud-to-cloud account linking, both sockets individually controllable. Same internet dependency as the Alexa cell.
• ✓ Apple Home: works — Native HomeKit — a real accessory in the Home app with both sockets exposed individually, not a cloud bridge, and Meross states the product is listed on Apple's own HomeKit site. Remote access needs an Apple home hub, which is Apple's requirement. ⚠ BUY THE RIGHT BOX: Meross sells non-HomeKit variants of its plugs under near-identical names, and only the HK-suffixed SKUs carry HomeKit — this record covers MSS620BHK specifically.
• ? SmartThings: inconclusive — Two Meross surfaces disagree and neither is decisive for this exact SKU, so this cell is left unknown rather than guessed. Meross's product site lists SmartThings among the ecosystems for the MSS620US variant; the US store's own MSS620BHK listing names Apple Siri, Amazon Alexa and Google Assistant and does NOT mention SmartThings. Our existing Meross record already documents that the company claims SmartThings for one model in a family and not another, so the family cannot be generalised across.
• ◐ Home Assistant: partial — There is NO official Home Assistant integration for Meross — Home Assistant publishes no Meross integration of its own, and Meross never mentions Home Assistant in its own materials, so nothing here is a route the maker supports. The community integration people actually use is well maintained and genuinely runs on your own network, but even that one needs a device key pulled out of your Meross cloud account first, so it is not cloud-free to set up. Recorded as partial because a well-supported community project is not the same thing as a supported integration.

Connection: Wi-Fi · Hub for full use: Yes (No hub or bridge — it joins 2.4 GHz Wi-Fi directly, and Meross states 'Works with the 2.4G Wi-Fi you already have. No hub required.' One caveat that is Apple's rule rather than Meross's: controlling it through Apple Home from outside the house needs an Apple home hub (HomePod or Apple TV), the same condition that applies to every HomeKit accessory.) · Works offline: Partly — some of it keeps working without the internet and some of it does not

Tapo Smart Wi-Fi In-Wall Outlet, Matter, Energy Monitoring (P210M) — the catch, per ecosystem ~$25.99 $25.99 at time of research (2026-09-17), from TP-Link's own US Tapo store listing for the single-pack (SKU 'Tapo P210M'), in stock when read — never treated as a live price. ⚠ THIS CORRECTS THIS RECORD: it previously stated that no first-party TP-Link or Tapo store listing for this model had been read, and that was wrong. The listing exists and carries a price; what hid it is that the store files this model under a different address than its model name, so an earlier look for it found nothing and that absence was written down as fact. It was found this time by reading TP-Link's whole smart-plugs store section rather than looking for one address. TP-Link's product page and its own P210M(US) datasheet still publish no price — the store is the only first-party surface that does. No price was taken from a third-party retailer or a search summary.

• ✓ Amazon Alexa: works — Matter is the documented mechanism: the quick start guide's Matter section says 'You can integrate your Tapo Matter device into your preferred ecosystem, such as Amazon Alexa, Apple Home, Google Home, and more', and the product page lists Alexa in its compatibility line. Two practical limits. You need a Matter-capable Echo — TP-Link's own wording is 'Requires a hub of your chosen third-party platform'. And the energy monitoring that distinguishes this outlet is a Tapo-app feature; TP-Link documents no route by which per-outlet energy or bill estimates reach Alexa.
• ✓ Google Home: works — Same Matter commissioning path, with Google Assistant and Google Home named in TP-Link's own materials. Needs a Matter-capable Google hub, not just the Google Home app on a phone. Energy data stays in the Tapo app.
• ✓ Apple Home: works — Apple Home is reached through Matter — TP-Link names Apple Home in the quick start guide's Matter section — and no native-HomeKit path is documented or needed. Requires a HomePod or Apple TV acting as the Matter controller. One installation detail specific to an in-wall device that is easy to overlook until you have already screwed the wallplate on: the Matter QR code is on the label in the package, and the numeric code is on the device itself, reachable only 'by detaching the wallplate and unscrewing its bracket'. Photograph the code before installation.
• ✓ SmartThings: works — TP-Link's product page names 'Samsung SmartThings' in its compatibility list, and the mechanism is the same Matter commissioning flow the quick start guide describes. Requires a SmartThings hub capable of acting as a Matter controller.
• ✓ Home Assistant: works — Confirmed from Home Assistant's side, not TP-Link's: Home Assistant's core TP-Link integration lists 'P210M' by name among supported Tapo devices and 'connects locally to the devices without going via the TP-Link cloud'. Two caveats from the same documentation: a newer Tapo device 'will require your TP-Link cloud username and password to authenticate for local access', and some firmware versions 'require explicit activation of third-party integrations before they will allow access from Home Assistant'. A second route also exists — Home Assistant's Matter integration, since the device is Matter-certified — which avoids TP-Link credentials but requires a Matter server; the vendor integration generally exposes more of the energy data.

Connection: Matter · Wi-Fi · Hub for full use: No — verified that none is needed · Works offline: Yes — the core function runs on the device or your home network

Tapo Smart Wi-Fi Outdoor Plug, Matter (P400M) — the catch, per ecosystem ~$25.99 $25.99 at time of research (2026-09-17), from TP-Link's own US Tapo store listing for this model (SKU 'Tapo P400M') — never treated as a live price. ⚠ IT IS STILL SOLD OUT, AND THE PRICE IS RECORDED ANYWAY: the listing now prints a figure where it printed none when it was read on 2026-07-29, so TP-Link's own asking price is established even though you cannot buy it there today. Stock state is a fact about the product, never a reason to withhold what the maker charges. What is established about availability is two readings 50 days apart — 2026-07-29 and 2026-09-17 — both showing it unavailable on TP-Link's own store, with no discontinuation notice published anywhere; nothing was read about the days in between, so this is not a claim of continuous unavailability. TP-Link's product page and its own P400M datasheet still publish no price. No price was taken from a third-party retailer or a search summary.

• ✓ Amazon Alexa: works — Matter is the documented mechanism, not an inference: the datasheet's setup section says to scan the Matter QR code in 'your preferred smart home app' and names Alexa, and the page carries a 'works with alexa' badge. On/off is this device's entire function, so full. The requirement to budget for: TP-Link states 'A Matter-supported controller and smart home app of the same ecosystem are required' — a Matter-capable Echo, not just the Alexa app on a phone. Each outlet appears separately and can be named.
• ✓ Google Home: works — Same Matter mechanism, with a 'works with Google Home' badge on TP-Link's own datasheet and Google Assistant named in the voice-control section. Needs a Matter-capable Google hub (Nest Hub / Nest Wifi Pro / Google TV Streamer class device) — the phone app alone will not commission it.
• ✓ Apple Home: works — Apple Home is reached through Matter, and Siri is named by TP-Link directly ('Use simple voice commands with Alexa, Siri, or Google Assistant'). No native-HomeKit path is documented for this model and none is needed. Platform requirement rather than a device limit: a Matter controller of the same ecosystem is required, which for Apple means a HomePod or Apple TV acting as the home hub.
• ✓ SmartThings: works — TP-Link's product page names 'Samsung SmartThings' in its compatibility list and the route is the same Matter commissioning flow. Requires a SmartThings hub that can act as a Matter controller; SmartThings' phone app alone is not sufficient.
• ✓ Home Assistant: works — Worth reading closely, because the obvious route is the wrong one. Home Assistant's official TP-Link integration — which does list the Kasa HS300 and the Tapo P210M by name — does NOT list P400M, so the vendor-specific local integration is not the path here. What is: Home Assistant's own Matter integration, which accepts any Matter-certified device, and TP-Link certifies this one as Matter. That makes the route protocol-level rather than brand-level, and it needs Home Assistant's Matter server; no TP-Link cloud credentials are involved. Recorded full because on/off is the whole function, with the mechanism named so nobody wastes an evening in the wrong integration.

Wyze Plug Outdoor (SVB-WLPPO1) — the catch, per ecosystem ~$29.98 price at time of research, re-checked 2026-09-17 on Wyze's own store and unchanged in seven weeks: $29.98 for the 1-pack and $57.98 for the 2-pack ($28.99 each), both in stock. Never treated as a live price, and no discount was in effect on either — worth saying because this store does run sales, and the figure above is the ordinary price rather than a promotion that will lapse.

• ✓ Amazon Alexa: works — The one ecosystem Wyze documents for this specific model. Wyze's own integrations page files the Wyze Plug Outdoor under its Alexa-connected list, and the product page carries a 'Voice commands with Alexa' section. Control runs through the Wyze skill and Wyze's cloud, so it depends on both Wyze's service and your internet connection; there is no local route and no Matter on this model.
• ? Google Home: inconclusive — Two of Wyze's own pages disagree, and we record the disagreement rather than pick the friendlier answer. Wyze's integrations page splits its products into those that work with both Alexa and Google Assistant and those that are Alexa-only, and it places the Wyze Plug Outdoor in the Alexa-only group while listing the indoor Wyze Plug under both. Against that, Wyze's support site has an article titled 'Is Wyze Plug Compatible with Alexa or Google Assistant?' whose summary answers yes for 'Wyze Plug', but that title names the indoor model, and we could not read the article itself. So the model-specific statement says no and the generic one says yes. Until Wyze clears that up, treat Google support as unsettled.
• ✗ Apple Home: doesn't work — Positively evidenced absence, not an unchecked blank. Apple Home speaks only HomeKit or Matter. Wyze's integration page enumerates the ecosystems it supports — Alexa, Google Assistant and IFTTT — and Apple, HomeKit and Siri appear nowhere on it; the product page names no Apple path either; and this model carries no Matter certification and no Thread or Matter protocol support, so the only two doors into Apple Home are both closed.
• ✗ SmartThings: doesn't work — Same basis as Apple: SmartThings is absent from Wyze's own enumeration of supported ecosystems (Alexa, Google Assistant, IFTTT) and from the product page, and with no Matter support there is no protocol-level route that would work regardless of vendor intent. Community SmartThings drivers may exist; none is a Wyze-supported path and none was verified here.
• ? Home Assistant: inconclusive — Wyze documents no Home Assistant support for this plug. What Wyze publishes is a smart-home article, re-read on 20 September 2026 and titled "How Wyze Integrates Seamlessly With Alexa, Google Assistant, and IFTTT", which walks through those three and lists which Wyze products work with each — an article written around three integrations is not a complete statement of what the company supports, so Home Assistant being absent from it settles nothing. Community Home Assistant integrations for Wyze accounts are widely used, but none was checked against this model, and a community integration built on a maker's private cloud connection is a materially different promise from a supported one. Recorded as unanswered rather than no, because the absence of maker support is not evidence that the community route fails.

Govee Smart Plug Outlet Extender with Night Light (H5089) — the catch, per ecosystem ~$34.99 at time of research — read from Govee's own US store, shown as $34.99 against a $49.99 struck-through price under a running site-wide sale banner and a countdown timer, so it is a promotional figure with an expiry rather than a stable one. Never treated as a live price.

• ✓ Amazon Alexa: works — Govee names Alexa in a titled feature line — 'Supports Alexa/Google: Experience a smart ecosystem designed for seamless connectivity across your devices. Enjoy hands-free convenience with full voice control support' — and the route is the usual Govee cloud account link, so it depends on your internet. Two limits worth knowing: only the two smart sockets and the night light are things voice can address, and Govee publishes no command list, so whether the night light's colour and its 15+ effects are reachable by voice as opposed to only in the app is undocumented.
• ✓ Google Home: works — Named in the same feature line as Alexa and reached the same way, with the same internet dependency and the same undocumented command scope.
• ✗ Apple Home: doesn't work — Apple Home, HomeKit, Siri and Matter appear nowhere on Govee's product page or anywhere in its H5089 user manual, and this is one of the rare cases where the specification table settles the question rather than merely staying silent: the manual's Network row reads 'Bluetooth 5.0 or above, Wi-Fi4' and names no Matter or Thread radio, so there is no certified route for Apple Home to take on this device. We record it as a no on that hardware evidence plus a two-document omission, not on an outright 'not supported' statement, which Govee does not make.
• ? SmartThings: inconclusive — Unknown rather than none, and the distinction matters here. Govee's feature line names exactly two voice platforms, Alexa and Google, and SmartThings is not among them — but silence is not a refusal, and unlike the Apple case there is no architectural bar: a SmartThings connection for a Wi-Fi device would run cloud-to-cloud from Govee's service and would not care what radio the device carries. Govee documents no SmartThings route for this model and Samsung's own materials do not name it, so nothing is claimed either way.
• ✗ Home Assistant: doesn't work — Home Assistant ships two Govee integrations and neither one reaches this product. 'Govee lights local' is written for Govee LIGHTS on your own network, which this outlet extender is not. 'Govee Bluetooth' works from an explicit model list — hygrometers, thermometers, motion, contact, presence, button and leak sensors, named individually as H5051, H5075, H5121, H5125 and so on — and H5089 is not on it. There is no Govee integration in Home Assistant's list that works through Govee's servers at all, and Govee names Home Assistant nowhere on its own product page or in its manual. We record this as a no on the strength of Home Assistant's own model list leaving this device out, which is stronger evidence than a general silence.

Leviton Decora Smart Wi-Fi Tamper-Resistant Outlet, 2nd Gen (D215R) — the catch, per ecosystem ~$34.99 $34.99 at Leviton's own store, read 2026-08-28 (price at the time we researched it; Leviton may change it). This closes a gap this page carried from the day it was written, when we had read no Leviton store listing at all. ⚠ THE STORE'S PRODUCT CODE DOES NOT EXACTLY MATCH THE ONE ON THIS PAGE, AND WE RECORD THE PRICE ANYWAY — the reasoning is here rather than assumed, because attaching a price across a product-code boundary is how a catalogue quietly lies. Leviton's own single listing carries BOTH identifiers: its web address ends 'decora-smart-wi-fi-tamper-resistant-outlet-2nd-gen-d215r-1bw' while its title reads 'Decora Smart Wi-Fi Tamper-Resistant Outlet (2nd Gen), D215R-1RW'. Leviton is equating the two in one place, so this is not a price stitched together from two different documents. ⛔ COLOUR WAS THE OBVIOUS TRAP AND WE CHECKED IT rather than waving past — we have been bitten before by a product priced differently by colour. It does not apply: the listing has exactly ONE option, and Leviton's own description sells colour as an accessory rather than a separate product — 'six color options' delivered by 'optional DSRKT color change kits in Ivory, Black, Gray, Brown and Light Almond'. There is one of these a buyer can purchase from Leviton and it costs $34.99. Leviton's own product page still shows no price, which is why we needed the store at all.

• ✓ Amazon Alexa: works — First-party and documented with a mechanism, not just a badge: Leviton's product-data sheet describes controlling 'connected lighting and loads from compatible Alexa built-in devices such as an Amazon Echo, Echo Show, the Alexa app, or even the Decora Smart Voice Dimmer'. The route is the My Leviton cloud link, so voice and remote control depend on Leviton's service and your internet connection — unlike the HomeKit path, which is local.
• ✓ Google Home: works — Documented by Leviton with its own section — 'Use your voice to control connected lighting and loads with Google Assistant or from the Google Home app' — and a 'works with Hey Google' badge. Same dependency as Alexa: the link runs through the My Leviton cloud, so an internet or service outage takes it with it.
• ✓ Apple Home: works — Native HomeKit, which on this generation is a genuine advantage over Leviton's newer Matter-only hardware: the product-data sheet carries a 'Works with Apple HomeKit' badge and says to 'Add to an Apple HomeKit network and control with the native Apple Home app on your iOS device, providing compatibility with Siri for voice control'. No Matter needed and no HomePod needed for basic local control — though HomeKit automations and away-from-home access do need a HomePod or Apple TV, which is Apple's rule rather than Leviton's. The hazard to know about before you accept a firmware update: Leviton states that updating a 2nd Gen device to Matter firmware 'will remove your Decora Smart Wi-Fi device's current connection to Apple HomeKit', after which it must be re-added using a Matter pairing code. D215R is not currently on Leviton's Matter-eligible list, so that update is not offered for it today.
• ◐ SmartThings: partial — Listed but not explained, which is exactly why it is not recorded as full. SmartThings appears in the product-data sheet's features list ('Works with My Leviton, Amazon Alexa, Hey Google, HomeKit/Siri, IFTTT, SmartThings, Schlage') — a first-party technical claim rather than storefront copy — but unlike Alexa, Google, HomeKit, IFTTT and Schlage, SmartThings gets no section of its own and no mechanism is documented anywhere in Leviton's materials for this model. Recorded partial for the undocumented mechanism, following the same convention this catalog used for the D315S and the Tailwind iQ3.
• ? Home Assistant: inconclusive — Leviton names no Home Assistant support for this model. On the Home Assistant side a route plausibly exists but does not name this device: there is an integration for the Decora Smart Wi-Fi line that works through your My Leviton account, and Home Assistant's own page marks it a 'Legacy integration', community-maintained, that asks Leviton's servers for updates at intervals. Its documented device list names six models — DW6HD1-BZ, DW15P-1BW, DW15S-1BZ, D215S-2RW, DN15S-1BW and D2MSD-1BW — and this outlet is not one of them. Since it signs into a My Leviton account rather than a specific device, it may well pick this outlet up; that is our inference, not a documented claim, so we leave the question open with the reasoning attached rather than borrowing confidence from a sibling model.

Meross Smart Wi-Fi Surge Protector Power Strip (MSS425FHK) — the catch, per ecosystem ~$37.99 At the time we researched it — read from Meross's own store data rather than from the page as it renders, shown as $37.99 against a $48.99 was-price, SKU MSS425FHK-US. Never treated as a live price. We did not read stock state from that source and deliberately claim nothing about it here.

• ✓ Amazon Alexa: works — Named directly by Meross in its voice-control line and reached by account linking through Meross's cloud, with each outlet addressable separately by voice. Being cloud-routed it stops working when your internet does — unlike the Apple Home path on the same device, which is the sharpest practical difference between the two on this product.
• ✓ Google Home: works — Named in the same Meross sentence as Alexa and Apple, reached the same way, with the same internet dependency. Per-outlet control; the USB bank is one thing rather than four.
• ✓ Apple Home: works — Native HomeKit rather than a cloud bridge, and Meross states the version floor itself: 'Compatible With Apple HomeKit(iOS 13 or above), Siri'. Each of the four AC outlets is individually controlled, so they appear as separate accessories; the four USB ports are group-controlled and are not four separate things in the Home app. Remote access needs an Apple home hub — Meross names 'a HomePod, an Apple TV 4K or Apple TV HD or an iPad' — which is Apple's requirement, not a Meross limitation. ⚠ Buy the HK model: Meross sells non-HomeKit variants of this strip under near-identical titles.
• ✓ SmartThings: works — SmartThings is named on this product's own Meross listing — 'Compatible With Apple HomeKit(iOS 13 or above), Siri, Alexa, Google Home and SmartThings' — which is what separates it from the Meross MSS620 outdoor plug elsewhere in this catalogue, where we left the answer open because two Meross pages disagreed about that model. The route runs between Meross's service and Samsung's, so it carries the same internet dependency as Alexa and Google here. Meross publishes no SmartThings setup article, so expect on/off and scheduling rather than a documented feature list.
• ◐ Home Assistant: partial — There is NO official Home Assistant integration for Meross — the page one would live at does not exist, and Meross names Home Assistant nowhere in its own materials — so nothing here is a route the maker supports. The community meross_lan project is well maintained and genuinely runs on your own network, and it names this model family in its own supported-hardware list: 'MSS425: Smart Wi-Fi Surge Protector (multiple sockets power strip)'. Even so, setting it up is not server-free: meross_lan needs a device key taken from a Meross account. We call this partial because a well-supported community project is not a supported integration — the same call we made on the Meross outdoor plug, applied here with the model named rather than assumed.

Connection: Wi-Fi · Hub for full use: Yes (No hub or bridge is needed to use it — Meross states 'Works with any 2.4GHz or Dual Band WiFi router. No hub required.' The one condition is Apple's rather than Meross's, and Meross spells it out: 'To enable HomeKit remote control, a HomePod, an Apple TV 4K or Apple TV HD or an iPad is needed as a Homekit bridge to connect it to your home WiFi network.' Without one, Apple Home control works at home and not from away — and Meross names its own app as the alternative for that case.) · Works offline: Not checked — we have not established whether this keeps working without the internet

Eve Energy (4th generation, Matter) — the catch, per ecosystem ~$43.95 at time of research, from Eve's own US store page for the single pack in September 2026 — never treated as a live price

• ◐ Amazon Alexa: partial — On/off, scenes, automations, and remote access work via Matter, but energy monitoring does not — and that is now confirmed from Amazon's side rather than only Eve's. Amazon's own list of the Matter clusters Alexa supports (last updated 2026-04-08) carries no electrical power measurement and no electrical energy measurement cluster at all, and maps a plug to on/off control only. The missing energy data is a platform gap, not a device limitation. Eve-app extras (schedules, status LED, child lock) are unreachable from an Alexa-only setup.
• ◐ Google Home: partial — Core control works via Matter; energy monitoring does not, and Google's own documentation shows why. Google's supported-Matter-devices matrix gives the plug device type on/off control with no electrical power or energy measurement cluster, and files those two clusters under a separate Electric Meter device type whose Home ecosystem type the same table marks N/A. One honest caveat about how fresh that answer is: Google's page carries a last-updated date of 2024-12-20, so it is a weaker temporal answer than Amazon's. Eve's Android app covers devices connected through Google Home, which is the route to schedules and device settings on Android.
• ◐ Apple Home: partial — Energy monitoring — the reason to choose this plug over a cheaper one — does not appear in the Apple Home app. Eve names only Samsung SmartThings and Home Assistant as the platforms with native energy management. You still get the data, but only inside Eve's own iOS app, which also carries the built-in schedules, the status-LED setting and the child lock. On/off, scenes, automations and remote access all work normally through Apple Home over Matter.
• ✓ SmartThings: works — One of the two platforms where Eve says energy data surfaces natively: 'Energy management features currently available on the Samsung SmartThings and Home Assistant platforms.'
• ✓ Home Assistant: works — Listed by Eve as a supported platform with native energy monitoring; connects via Matter with a Thread border router (Eve names HA Green/Yellow/Connect ZBT-1/ZBT-2).

Connection: Thread · Matter · Hub for full use: Yes (Thread border router + Matter controller before it works at all. Eve's wording: 'this Matter-enabled device requires a hub that supports both Thread and Matter.' Eve's hub guide names, per ecosystem: Apple — HomePod (2nd gen), HomePod mini, Apple TV 4K (the Wi-Fi + Ethernet model is the one with Thread); Alexa — Echo (4th gen) and various Echo Show/Hub/Studio models, eero routers; Google — Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro, Google TV Streamer; SmartThings — Hub V3, Station, Aeotec hubs; Home Assistant — Green, Yellow, Connect ZBT-1/ZBT-2. Setup needs an iPhone/iPad on current iOS or Android 8.1+.) · Works offline: Yes — the core function runs on the device or your home network

Legrand radiant Smart 15A Receptacle with Wi-Fi, Matter-Enabled, White (WWMRR15WH) — the catch, per ecosystem ~$46.36 at time of research — read from Legrand's own legrand.us product page, which showed 'In Stock' at this figure with an add-to-cart control. Never treated as a live price.

• ✓ Amazon Alexa: works — Matter is the whole mechanism and Legrand names Alexa directly: 'Device comes with Matter built-in, allowing for greater interoperability and compatibility with the latest smart home assistants and platforms – including Apple HomeKit, Google Home, Amazon Alexa and Samsung SmartThings', with the specification table's Works With row repeating 'Amazon Alexa, Apple Home, Google Home, Matter, Samsung SmartThings'. The cost is the controller: you need a Matter-capable Echo, not just the Alexa app, and Legrand states the requirement without hedging. The upside is that commissioning is a QR scan and no Legrand app or account is involved. Only the top outlet appears as a controllable thing — the always-on half is invisible to every platform.
• ✓ Google Home: works — Named in the same compatibility sentence and the same Works With row, reached the same way. Needs a Matter-capable Google hub rather than only the Google Home app on a phone. Same single-controlled-outlet limit.
• ✓ Apple Home: works — Legrand names Apple HomeKit in its compatibility sentence and Apple Home in its Works With row, and the route is Matter rather than a legacy HomeKit implementation — so a HomePod or Apple TV acting as the Matter controller is part of the real cost. Setup is Legrand's stated 'Simply scan the Matter QR code on the device with your smartphone's camera or smart home application'. One in-wall detail worth acting on before the wallplate goes back: the Matter code is on the device, so photograph it during installation rather than after.
• ✓ SmartThings: works — Samsung SmartThings is named in both first-party lists and joins through the same Matter commissioning flow, requiring a SmartThings hub capable of acting as a Matter controller. Nothing SmartThings-specific is documented beyond that, so expect on/off of the controlled outlet and no more.
• ✓ Home Assistant: works — Reached through Home Assistant's own Matter integration, which needs the Matter server add-on running — and NOT through the integration that carries Legrand's name. That distinction is the trap on this record: Home Assistant's 'Legrand' page is a virtual integration whose support 'is provided by the Netatmo integration', covering Legrand's rebranded Netatmo devices over a Cloud Polling connection. This receptacle is a radiant Collection Matter device and has nothing to do with that path; a household that installs the Legrand integration looking for it will not find it. Legrand itself names no platform beyond the four it lists, so the Home Assistant route rests on the Matter certification Legrand does claim rather than on either party naming the other.

Connection: Matter · Wi-Fi · Hub for full use: Yes (Yes for every ecosystem path, and Legrand states it as a flat condition of use rather than as a footnote: 'Matter Controller Required: A compatible Matter controller is required for successful installation.' In practice that means a HomePod or Apple TV for Apple Home, a Matter-capable Echo for Alexa, a Matter-capable Google hub for Google Home, or a SmartThings hub — Legrand maintains its own controller list at legrand.us/matter. There is no Wi-Fi-only vendor-app path that works without one, which is a real difference from most Wi-Fi outlets in this subcategory.) · Works offline: Yes — the core function runs on the device or your home network

Enbrighten In-Wall Z-Wave Tamper-Resistant Smart Outlet (58449) — the catch, per ecosystem ~$49.99 price at time of research (2026-09-16), read from Jasco's own store, which showed item 58449 in stock and ready to ship. ⚠ This is $5 above the previous $44.99, which this record carried as of 2026-08-16 — Jasco's own list price moved, and there is no compare-at or sale price behind it.

• ◐ Amazon Alexa: partial — Voice works, but never directly: no Echo speaks Z-Wave, so Alexa reaches this outlet only through whichever hub you paired it to, and it is that hub's Alexa connection doing the work. Jasco's own sentence keeps the two halves together: Alexa and Google Assistant compatible, 'requires a Z-Wave certified hub'. Recorded as partial because Jasco publishes no Alexa setup guide and no list of commands, so what you can say, and whether the always-on half ever shows up, is a question about your hub rather than about this product.
• ◐ Google Home: partial — Identical standing to the Alexa cell, from the identical sentence: Google Assistant is named, and named in the same breath as the hub requirement. Jasco publishes no Google setup documentation, so the capability depth belongs to the hub.
• ✗ Apple Home: doesn't work — Apple Home, HomeKit and Siri appear nowhere on Jasco's product page, which names its voice platforms (Alexa and Google Assistant) and then lists eleven hub brands without an Apple product among them. The physics agrees: Apple Home does not speak Z-Wave and none of Apple's hubs carry a Z-Wave radio, so there is no route for it to take. Recorded as 'no' on the strength of a maker's list that omits Apple, rather than on an outright 'not supported' statement, which Jasco does not make.
• ✓ SmartThings: works — SmartThings is the first hub Jasco names, in both of the sentences that matter. What that buys is on, off and scheduling of the controlled outlet through a SmartThings hub with a Z-Wave radio; the always-on outlet is not controllable on any platform. Several of the hubs in Jasco's list are historical, Wink in particular, on a page that has plainly not been rewritten in years, so treat the list as evidence that the outlet is a standard Z-Wave device rather than as a current compatibility roster.
• ✓ Home Assistant: works — The strongest cell on this record, and it comes from Home Assistant rather than from Jasco. Home Assistant's own Jasco page says Jasco is a member of the Works with Home Assistant partner programme for its Z-Wave products, that Jasco Z-Wave devices work locally through Home Assistant's Z-Wave support (a Z-Wave stick is required), and that status updates arrive instantly. Two practical costs: you supply the Z-Wave stick, and Home Assistant marks the integration as community maintained. Scoped carefully: Home Assistant's statement is about Jasco's Z-Wave products as a class rather than about item 58449 by name, but it describes a standards-based path that any certified Z-Wave device takes, which is why this cell is not left unknown.

Connection: Z-Wave · Hub for full use: Yes (Yes: a Z-Wave certified hub is required, and there is no Jasco app or cloud to use instead. Jasco's own wording is 'requires a Z-Wave certified hub from brands including SmartThings, Ring Alarm, Wink, ADT Pulse, ADT Command, Trane, Vivint, Nexia, Honeywell, HomeSeer, Vera and more'. The hub you already own decides everything about this outlet except its electrical behaviour: which app you use, whether voice works, and what an automation can do with it.) · Works offline: Yes — the core function runs on the device or your home network

Eve Energy Strip (connected triple outlet) — the catch, per ecosystem ~$109.95 Price at the time of research (2026-08-26). $109.95 is what Eve's own US product page charges for the single pack: the buy panel reads 'SINGLE PACK $109.95' beside 'YOUR CHOICE / Single pack / Add to cart', and the same figure appears on Eve's US store index for this product. A two-pack is offered at $189.90 against a stated list price of $219.90 ('Save $30'); only the single-device figure is recorded here. ⚠ Where else you can buy it is not established. Eve's page says 'Buy from our partners' but builds that dealer list only once the page is running in a browser, and no partner link appeared when the page was read — so nothing is asserted here about which retailers carry the strip, in either direction.

• ✗ Amazon Alexa: doesn't work — Eve's product page documents exactly one control protocol for this model — HomeKit over Wi-Fi — and names no Alexa skill, no Matter certification and no Thread radio. Alexa cannot speak HomeKit, so on everything Eve publishes there is no route an Echo could take. ⚠ What that rests on, said plainly: an enumeration and a silence, not a denial. Eve publishes no 'not supported' statement for this strip, and no certification registry has been checked on this record — so the cell carries an absence marker naming what would overturn it. Note the contrast inside Eve's own lineup, which is what makes this a real buying trap: Eve's Matter-era products (including the Eve Energy plug in this catalog) DO work with Alexa. The strip does not.
• ✗ Google Home: doesn't work — Same basis as Alexa: HomeKit is the only protocol Eve documents for this model, Google Home speaks Matter or its own cloud integrations but not HomeKit, and Eve publishes no Google integration for the strip. ⚠ Again this is what Eve's page enumerates and leaves out rather than a stated exclusion, so the cell carries an absence marker with its overturn condition.
• ✓ Apple Home: works — Native HomeKit, and the only ecosystem Eve supports on this model — the whole product is designed around Apple Home. Each of the three outlets shows up as its own accessory in the Home app and can be switched by Siri or the Home app locally. Two limits worth knowing before you buy: automations and control from outside the house need a HomePod or Apple TV (4th generation or later) acting as a home hub, per Eve's own requirement statement; and the energy figures do not appear in Apple's Home app — 'The Eve app visualizes total consumption by day, week, month, and year', so the reason many people buy it lives in Eve's iOS app rather than Apple's.
• ✗ SmartThings: doesn't work — Same again: SmartThings has no HomeKit client, Eve publishes no Matter certification for this model, and Eve names no SmartThings support anywhere on the product page. ⚠ A checked silence rather than an unverified blank — and rather than a vendor denial, which is why an absence marker rides on the citation.
• ✓ Home Assistant: works — There IS a route, it is local, and it comes at a hard price — which is exactly the kind of trade a compatibility table usually hides. Home Assistant's core HomeKit Device integration pairs directly with 'Works with HomeKit' accessories over the local network with no cloud involved. But Home Assistant's own documentation states the constraint plainly: 'HomeKit devices can only be paired to a single controller at once', and 'If your device is in your network but is paired with an Apple device via HomeKit: Remove the device from the Apple Home app. Otherwise you won't be able to pair it with Home Assistant.' So this is Apple Home OR Home Assistant, never both — and since Apple Home is the strip's only other ecosystem, choosing Home Assistant means giving up Siri and the Home app entirely.

Connection: Wi-Fi · Hub for full use: No — verified that none is needed · Works offline: Yes — the core function runs on the device or your home network

Belkin Wemo Smart Plug (Wemo Mini WSP080 and WiFi plug line) — the catch, per ecosystem

• ✗ Amazon Alexa: doesn't work — Dead since 2026-01-31 — Belkin shut down Wemo cloud services as scheduled, and voice assistant integrations ran through that cloud. The only survivor path is Apple HomeKit: units already configured in Apple Home keep working locally, which does not restore Alexa control.
• ✗ Google Home: doesn't work — Dead since 2026-01-31 — Google Home/Assistant control ran through the Wemo cloud, which Belkin shut down as scheduled. Only units pre-configured in Apple HomeKit retain any control (locally, via Apple Home); nothing restores Google control.
• ◐ Apple Home: partial — HomeKit (not Matter), local only, and only for HomeKit-capable models (WSP080, WSP090, F7C063; WSP100 Thread) that were already configured before 2026-01-31. Belkin states new HomeKit setup is no longer possible after that date.
• ✗ SmartThings: doesn't work — Belkin's end-of-support notice says all cloud-dependent third-party integrations stopped when the Wemo cloud shut down on 2026-01-31; SmartThings is not named individually, but its integration was cloud-to-cloud and is covered by the blanket shutdown. No path to SmartThings control remains for the WiFi plug line.
• ? Home Assistant: inconclusive — Whether this plug keeps working in Home Assistant after Belkin's shutdown still has no official answer, six months on. Home Assistant's official Wemo integration is documented as working over your home network with no cloud, but Belkin's notice says nothing about whether the plug's own local control survives the shutdown, and a new plug can no longer be set up on WiFi without the retired Wemo app. Two dated signs narrow it. Home Assistant still ships and documents the integration as working locally in version 2026.7.4, with no notice that it is going away. And a Home Assistant bug report opened 2026-07-27 describes Wemo devices that were being controlled until the 2026.7.4 update and then stopped responding while still on the network. That suggests plugs set up before the shutdown were still working locally months after it, and that this particular break came from a Home Assistant update rather than Belkin's cloud. One unverified report does not settle compatibility, so this stays unknown rather than becoming a claim that it works.

Connection: Wi-Fi · Hub for full use: Yes (No hub or bridge. The plug has its own Wi-Fi radio and joins your network directly. Belkin's own documentation names no bridge for this plug, and nothing sat between it and the network in either of its two setup routes. Worth knowing if you have read otherwise about the brand: older Wemo LED bulbs did need a Wemo Link bridge, so "Wemo needs a bridge" is true of some Wemo hardware and false of this plug.) · Works offline: Yes — the core function runs on the device or your home network

GE Cync Outdoor Smart Plug, Matter (CPLGOD2BLMS) — the catch, per ecosystem

• ✓ Amazon Alexa: works — GE names Amazon Alexa directly and says the route is Matter. On and off is the whole job this plug does, so nothing is lost in translation. What to budget for: Matter needs a Matter-capable Echo in the house, not just the Alexa app on a phone, and GE marks those platform devices sold separately on its own page.
• ✓ Google Home: works — Named by GE in the same sentence as Alexa, through the same Matter route. It needs a Matter-capable Google device — a Nest hub or Google TV Streamer class product — rather than the phone app alone, which GE signals by marking the platform sold separately.
• ✓ Apple Home: works — Apple Home is reached through Matter, and GE names it on its own page. This is the difference between the two outdoor Cync plugs: the Matter part number gets into the Home app, the other one does not, and only the barcode or the part number tells them apart. The requirement is a home hub — a HomePod or an Apple TV — because Apple needs one to commission a Matter accessory and to reach it from away. GE's own wording calls the platform devices sold separately.
• ✓ SmartThings: works — GE names Samsung SmartThings and the route is the same Matter commissioning flow. It needs a SmartThings hub acting as a Matter controller; the SmartThings phone app on its own will not do it. Again this is the Matter part number only — the non-Matter sibling has no SmartThings route at all.
• ✓ Home Assistant: works — GE does not name Home Assistant anywhere, and it does not need to: this cell rests on Home Assistant's own documentation, which says Home Assistant acts as a Matter controller and that Matter products run locally and allow local control without any internet connection or cloud service. This plug holds a current Matter certificate, so the route is the standard rather than anything GE builds. What it costs you: Home Assistant's Matter server, which its own documentation says is supported only on Home Assistant's own operating system, and a phone with the Home Assistant app to do the commissioning. No Cync account is involved in the Matter path.

Connection: Matter · Wi-Fi · Bluetooth · Hub for full use: Yes (No hub for the Cync app itself — GE describes this plug as connecting directly over your wireless network. But reaching it from Apple Home, Amazon Alexa, Google Home or Samsung SmartThings goes through Matter, and Matter needs a controller for that ecosystem in the house: a HomePod or Apple TV for Apple, a Matter-capable Echo for Amazon, a Nest hub or Google TV Streamer for Google, a SmartThings hub for Samsung. GE says as much on its own page by marking those platforms sold separately. One gap worth knowing before you buy: GE does not publish which wireless band this plug needs, and its sibling model is limited to the slower 2.4 gigahertz band.) · Works offline: Not checked — we have not established whether this keeps working without the internet

Kasa Smart Wi-Fi Outdoor Plug (EP40) — the catch, per ecosystem

• ✓ Amazon Alexa: works — TP-Link names Alexa on this model's own page, reached by linking your Kasa account to the Kasa skill. On and off is the whole job this plug does, so there is nothing missing from the voice control. Two limits worth knowing: each outlet shows up separately so you can name them, and the connection runs between TP-Link's service and Amazon's rather than across your own network, so voice control stops during an internet outage even though the plug itself keeps its schedule.
• ✓ Google Home: works — Named by TP-Link on this model's own page alongside Alexa, and set up the same way by linking the two accounts. Same shape as Alexa: full control because on and off is all there is, and it depends on the internet because the link is made between TP-Link's service and Google's.
• ✗ Apple Home: doesn't work — This plug does not work with Apple Home, and the check had a control that makes the answer solid rather than a guess. TP-Link names only Alexa and Google Assistant on this model's page, and the certifying body's own registry holds no Matter certificate for the EP40 — while it does hold one for the EP40M, the Matter version of the same plug, filed by the same company. So there is neither a vendor-built Apple route nor a standards route to fall back on. An Apple household wanting an outdoor plug should buy the EP40M or another Matter plug instead.
• ? SmartThings: inconclusive — TP-Link publishes no compatibility list for this plug — what its page carries is a voice-control feature blurb, 'Use simple voice commands with Alexa or Google Assistant to enjoy your hands free.' That names where voice works; it is not a statement about SmartThings in either direction, and TP-Link does name Samsung SmartThings on some other Kasa product pages. What is settled is that there is no standards route: the certification registry holds no Matter certificate for the EP40, though it does hold one for the EP40M, so any SmartThings support would have to be a connection TP-Link builds and maintains itself. Treat this as unanswered rather than as a no, and check TP-Link's current compatibility list before buying for a SmartThings home.
• ✓ Home Assistant: works — The strongest answer on this record, and it rests on the model name rather than on a guess about the device class: Home Assistant's own TP-Link documentation lists EP40 explicitly among the devices it supports. Home Assistant states the integration talks to the plug on your own network rather than through TP-Link's service, which means it keeps working when the internet does not. The catch is the sign-in: Home Assistant also states that newer Kasa devices need your TP-Link account email and password to authenticate for that local access, so a local connection still begins with a vendor account.

Connection: Wi-Fi · Hub for full use: Yes (No hub and no bridge. What TP-Link does require is a secured wireless network on the slower 2.4 gigahertz band — the plug cannot join a 5 gigahertz network, and TP-Link states that plainly — plus the free Kasa Smart app and a Kasa account. TP-Link also states an electrical condition that is easy to skip and is about safety rather than convenience: outdoors or in a wet location the plug must go into a receptacle with ground-fault protection.) · Works offline: Not checked — we have not established whether this keeps working without the internet

Kasa Smart Wi-Fi Plug Slim with Energy Monitoring (EP25) — the catch, per ecosystem

• ✓ Amazon Alexa: works — Named on the product's own page, which describes voice control through 'Alexa, Google Assistant, or Samsung SmartThings enabled devices'. The page names the platform without enumerating behaviours beyond voice control, so the depth beyond that is not certified here.
• ✓ Google Home: works — Named on the same first-party line as Alexa and SmartThings — and note TP-Link's wording, 'Google Assistant', the voice layer rather than Google Home as a platform. The distinction is not resolved on the page.
• ? Apple Home: inconclusive — ⚠ KASA'S OWN PAGE STILL DISAGREES WITH ITSELF ABOUT APPLE, and the shape of the disagreement changed in September 2026 — so this stays open rather than resolved in either direction. The voice-control section now tells you to 'pair your smart plug with Siri, Alexa, Google Assistant, or Samsung SmartThings', and the browser tab still reads 'Homekit'. But the compatibility line that says what the plug works with names only 'Alexa, Google Assistant, or Samsung SmartThings enabled devices' — Siri is not in it — and the word Apple does not appear anywhere on the page. Naming a voice assistant is also not the same as saying the plug shows up in Apple's Home app, which the page never says. When a maker's own page contradicts itself twice over, we record the contradiction rather than pick the flattering half. An Apple household should confirm this in the Home app before buying.
• ✓ SmartThings: works — 'Samsung SmartThings' is named directly in TP-Link's own compatibility line for this model — a first-party per-product statement, which is rarer on these shelves than it sounds; most SmartThings cells in this catalogue rest on Samsung's partner directory, which enumerates no models for US readers.
• ? Home Assistant: inconclusive — Not established. The only sentence on TP-Link's page for this plug that touches platforms is about talking to it, and it is phrased as an open class: 'Use simple voice commands to control your smart plug with any Alexa, Google Assistant, or Samsung SmartThings enabled devices.' Home Assistant is not a voice assistant and is not named anywhere on the page, and 'any … enabled devices' does not close a list whose gaps could mean no. We read no Home Assistant documentation naming the EP25 either. So this is unknown rather than unsupported, and it stays that way until one side or the other says something.

Kasa Smart Wi-Fi Power Strip, 6 Outlets (HS300) — the catch, per ecosystem

• ✓ Amazon Alexa: works — Named by TP-Link on both the legacy and current product pages, and each of the six outlets appears as its own controllable device. The mechanism is the Kasa skill over TP-Link's cloud — there is no Matter and no local Alexa path — so voice and remote control depend on TP-Link's service and your internet connection. TP-Link documents no route by which the per-outlet energy readings surface in Alexa; that data lives in the Kasa app.
• ✓ Google Home: works — Same standing as Alexa: named on TP-Link's own compatibility list, per-outlet control, cloud-to-cloud through the Kasa service with no local option and no Matter. Energy readings are not documented as reaching the Google Home app.
• ✗ Apple Home: doesn't work — A positively evidenced negative rather than an unchecked cell. Apple Home admits only HomeKit or Matter, and this model has neither: TP-Link's current Kasa page enumerates its voice support as 'Alexa and Google Assistant' with no mention of Apple, HomeKit, Siri or Matter anywhere, and the specification lists no Matter certification. With both protocol doors closed, there is no route regardless of vendor intent. Households that want an Apple-visible strip need a Matter model — TP-Link's own Tapo power strip line is where that appears, not here.
• ? SmartThings: inconclusive — Not established, and the first thing to correct is what TP-Link's page actually says: there is no compatibility list on it. The single sentence that touches platforms is about talking to the strip — 'Control your smart power strip using simple voice commands with Alexa and Google Assistant.' — and SmartThings is not a voice assistant, so a sentence about voice control leaves it unaddressed rather than ruled out. TP-Link's own Kasa FAQ then declines to answer per model, saying Samsung compatibility varies by model and pointing readers at Samsung's own compatibility pages. Community SmartThings drivers for Kasa devices exist and are not a supported path. Nobody has published an answer for this strip, and this catalogue will not supply one.
• ✓ Home Assistant: works — The one ecosystem where this strip is NOT cloud-bound, and it is confirmed from Home Assistant's side rather than TP-Link's: Home Assistant's core TP-Link integration lists HS300 by name and 'connects locally to the devices without going via the TP-Link cloud'. Three caveats from the same documentation, all of which bite in practice: newer Kasa firmware requires your TP-Link cloud username and password to authenticate for LOCAL access; some firmware versions 'require explicit activation of third-party integrations' in the Kasa app before Home Assistant can connect at all; and for power strips specifically, 'the energy monitoring state of Kasa power strip child plugs is only updated every 60 seconds', so per-outlet energy readings lag by up to a minute rather than streaming live.
