Every Smart Sensor Compared: What Each One Needs Before It Works (2026)

By SmartHomeWorkflow Team · Last updated 2026-09-17

Sensors are the first category in our library where the device on the shelf is only half the purchase. Ten of the eleven products below are inert or crippled without a specific second box, and which box differs by brand. So this directory leads with the column most sensor pages bury: what each one needs before it works. Every cell renders live from the same sourced records behind our compatibility checker.

SwitchBot Presence Sensor — the catch, per ecosystem ~$29.99 SwitchBot's own US store price for the sensor on its own, checked again on 2026-09-17 and unchanged from what we recorded on 2026-07-19 — a price at the time of research, never a live price. The bundle figures that follow are from the earlier 2026-07-19 check and were not looked at again: the other 'Presence Sensor' listings are bundles of the same unit (Hub Mini Matter combo $59.99, Bot 2-in-1 $52.99, 2-pack $54.99). ✓ Amazon Alexa: works — Requires a SwitchBot hub (Hub Mini, Hub 2, Hub Mini Matter Enabled or Hub 3); SwitchBot publishes a dedicated setup guide. ◐ Google Home: partial — Requires a hub, and SwitchBot documents a hard platform limit: Google Home does not allow the sensor to be used as an automation CONDITION at all. It reports state and nothing more — which for a presence sensor removes most of the reason to buy one. ◐ Apple Home: partial — Requires both a SwitchBot hub and an Apple Matter controller (HomePod or Apple TV). It arrives bridged rather than native, and bridged SwitchBot devices can surface under Matter Setup > Secondary Devices > Lab Feature (Beta) rather than as an ordinary accessory. ◐ SmartThings: partial — Requires a hub. SmartThings appears in SwitchBot's platform enumeration, but no dedicated setup guide or capability detail was found, so which entities and attributes actually surface is unconfirmed. ✓ Home Assistant: works — The one ecosystem that does NOT need a hub — Home Assistant's Bluetooth integration talks to the sensor directly.

Never treated as a live price. Corrected from $34, a migrated figure nobody had independently checked — the gap is a rounding, which is worth saying plainly because most of this docket's corrections have not been. ◐ Amazon Alexa: partial — Via Matter over Thread only — needs an Echo that is both Thread border router and Matter controller. Aqara states Alexa does not support the light-sensor function, so only motion is usable. ✓ Google Home: works — Via Matter over Thread — requires a Google Thread border router (e.g., Nest Hub 2nd gen) as the controller. ✓ Apple Home: works — Via Matter over Thread — requires a HomePod, a HomePod mini or a Thread-capable Apple TV 4K (the Wi-Fi + Ethernet model) as Thread border router and controller. Motion and light sensor both exposed. ✓ SmartThings: works — Via Matter over Thread — requires a SmartThings hub with Thread border router capability (Station, Hub v3, Aeotec). ✓ Home Assistant: works — Officially listed by Aqara; joins through Home Assistant's Matter integration, which needs the Matter server add-on plus a Thread border router. Connection: Thread · Matter · Hub for full use: Yes (Thread border router (HomePod mini or a Wi-Fi + Ethernet Apple TV 4K, Nest Hub 2nd gen, newer Echo devices, SmartThings hubs with Thread, or an Aqara Hub M3) plus a Matter controller in your ecosystem.

THIRDREALITY Smart Presence Sensor R2 — the catch, per ecosystem ~$39.99 thirdreality.com listed the Smart Presence Sensor R2 at $39.99 on 2026-08-14, and the same figure still shows as the regular price on 2026-09-18. It was not a discount: the 'compare at' price shown was the same as the selling price. Price at time of research, never a live price. ⚠ THE PRICE DOES NOT BUY ONE TODAY: on 2026-09-18 the maker's own store shows the sensor as 'Sold out'. Nothing on the page says the model is discontinued, so this reads as a stock gap rather than an end of sale — but it is the maker's own storefront, and it is the only place we have seen this sensor sold. ◐ Amazon Alexa: partial — Reachable only through an Echo that has a Zigbee radio built in — the vendor's compatibility line ends with 'Echo devices with built-in Zigbee hubs', which is a small subset of Echoes. A plain Echo Dot cannot host it. Recorded partial because the route exists but depends entirely on owning the right speaker, and the vendor names no Alexa capability detail beyond hosting. ? Google Home: inconclusive — Google is not named anywhere on this product's page — a token search of its copy returns zero occurrences — and Zigbee gives Google no direct route. Whether a given hub re-exposes the sensor to Google Home is a fact about that hub, not about this sensor. Recorded unknown rather than none because the vendor states no refusal. ? Apple Home: inconclusive — ⚠ THE PER-PRODUCT ASYMMETRY WORTH KNOWING: the vendor's own Smart Plug Gen2 copy names an Apple HomeKit route through its separately-sold Smart Bridge MZ1, and this sensor's page names no Apple route at all — zero occurrences of 'Apple', 'HomeKit' or 'MZ1'. Same brand, same protocol, different published answer, so the plug's bridge path must not be read across to this sensor. Recorded unknown: no vendor statement either way. ✓ SmartThings: works — Named directly by the vendor among its supported platforms, alongside Aeotec — which matters because Aeotec builds the SmartThings hub hardware. Requires a hub with a Zigbee radio; presence and absence are exposed as automation triggers. ✓ Home Assistant: works — The route the vendor documents in most detail, naming the stacks rather than the brand: 'Home Assistant (ZHA or Zigbee2MQTT)'. A standard Zigbee 3.0 device on a local coordinator — no vendor cloud in the path, and the five sensitivity levels are exposed as device settings on a Zigbee coordinator rather than locked in a vendor app. Connection: Zigbee · Hub for full use: Yes (A Zigbee hub or coordinator is REQUIRED — the vendor states 'Requires a compatible Zigbee hub or coordinator' and names the platforms it supports: 'Home Assistant (ZHA or Zigbee2MQTT), SmartThings, Aeotec, Homey, Hubitat, and Echo devices with built-in Zigbee hubs'.

Meross Matter Smart Presence Sensor (MS600) — the catch, per ecosystem ~$40.99 at time of research — $40.99 on Meross's own US store, read 2026-08-31, with the US/CA, EU, UK and AU variants all listed at the same figure. Never treated as a live price. ✓ Amazon Alexa: works — Named by Meross in its own multi-platform sentence, reached through Matter rather than a Meross skill. The vendor does not state which of the sensor's two detection modes surfaces to Alexa, so treat the exposed entity set as unestablished. ✓ Google Home: works — Named by Meross in its own multi-platform sentence, reached through Matter. As with Alexa, what the platform actually sees is not itemised by the vendor. ✓ Apple Home: works — Meross names HomeKit directly and adds a detail worth having: 'On the Matter platform, both presence and light sensors are displayed', so the ambient-light half is exposed and not just the presence half. ? SmartThings: inconclusive — Not established. SmartThings is absent from Meross's works-with sentence for this model, which names only Meross, HomeKit, Alexa and Google Home. Recorded as unknown rather than none: a marketing sentence that lists four platforms is not a compatibility matrix, and Matter support makes the platform plausible — but plausible is not evidence, and nothing read here establishes it. ? Home Assistant: inconclusive — Not established, and the shape of Meross's own sentence is why. Its product page says the sensor "integrates seamlessly with multiple platforms through the Matter framework, including Meross, HomeKit, Alexa, and Google Home" — a list introduced with "including", which gives examples rather than drawing a boundary. Home Assistant's absence from it is silence, not a refusal. The same sentence points at the route that would most likely carry it: this is a Matter device, and Home Assistant runs Matter devices itself. That is how the standard works rather than something Meross or Home Assistant has published about this sensor, so the answer stays open rather than becoming a yes. Connection: Matter · Wi-Fi · Hub for full use: Yes (No Meross hub and no Meross bridge — the sensor joins a 2.4GHz Wi-Fi network directly, and the words 'hub' and 'bridge' do not appear on its product page at all. ⚠ Stated as the vendor states it, and no further: Meross says the sensor reaches HomeKit, Alexa and Google Home 'through the Matter framework', and it does not say on this page what a Matter setup needs at the controller end. Nothing about a Matter controller is asserted here because no source read for this record states it about this model.) · Works offline: Not checked — we have not established whether this keeps working without the internet Full sourced profile for Meross Matter Smart Presence Sensor (MS600) →

Signify does not document the mechanism on this page — the earlier note here describing a cloud Hue skill was not supported by any cited source and has been removed rather than re-asserted. ✓ Google Home: works — Through the Hue Bridge; Signify lists Google Assistant among the voice assistants for this sensor, with the Bridge stated as required. The mechanism is not documented on the cited page, so no cloud-versus-local claim is made here. ✓ Apple Home: works — Via the Bridge's native HomeKit pairing; motion, light level, and temperature are exposed to Apple Home. ◐ SmartThings: partial — Listed as compatible via the Bridge, but community reports indicate SmartThings may surface motion only, without the temperature/light-level readings other platforms show. ✓ Home Assistant: works — Official first-class HA Hue integration via the Bridge: motion, light level, and temperature as separate entities; V2 (square) Bridge pushes state instantly.

Eve Room Indoor Air Quality Monitor — the catch, per ecosystem ? Amazon Alexa: inconclusive — Eve names Alexa nowhere for this sensor, and the page Eve publishes never takes the question up. Its support page describes an Apple setup and only that - an iPhone or iPad, a HomePod or Apple TV as the home hub, and the Home app and Eve's own app for the rest. There is no list of supported platforms anywhere on it, so nothing here leaves Alexa out; the subject simply never comes up, and a page that never raises it has not said no. Weigh the shape of that silence before you buy, though: this sensor speaks Thread and Bluetooth and is not a Matter device, so Alexa has no route to it. ? Google Home: inconclusive — Eve names Google nowhere for this sensor, and there is no list of supported platforms on its support page for Google to be missing from - the page describes an Apple setup and never raises other systems at all. Same reading as Alexa, and the same thing worth weighing: a Thread sensor that is not a Matter device gives Google Home no way in. ✓ Apple Home: works — This is a HomeKit accessory and Apple is not one platform among several - it is the platform. Eve's support page names what you need: an iPhone or iPad with the latest version of iOS or iPadOS, plus a HomePod or an Apple TV (4th generation or later) as a home hub if you want automations to run on their own or to check the sensor while you are away. Automations can be built in Apple's Home app (iOS 15.1 and later) or in Eve's own app, and a few jobs stay in Eve's app - exporting your recorded measurements to a spreadsheet, and restarting the calibration. The sensor joins your home over Thread and needs no bridge of Eve's own: the home hub Apple already asks for is the Thread border router too. ? SmartThings: inconclusive — Eve names SmartThings nowhere for this sensor, and its support page carries no list of supported platforms for SmartThings to be missing from - it describes an Apple setup and never raises other systems. Same reading as Alexa, and the same thing worth weighing: a Thread sensor that is not a Matter device gives SmartThings no way in. ? Home Assistant: inconclusive — Eve names Home Assistant nowhere for this sensor, and its support page carries no list of supported platforms at all - it describes an Apple setup and never raises the question. This one is worth separating from the general case: Eve's hub guidance does name Home Assistant's Green, Yellow and Connect ZBT-1/ZBT-2, but that guidance is about Eve's Matter accessories and this sensor is not one. Home Assistant publishes nothing naming this product either, so the answer stays open rather than inheriting a sibling product's. Connection: Thread · Bluetooth · Hub for full use: Yes (No to read it, yes for almost everything else, and Eve sets the boundary out in a section of its own. 'This device does not require a hub for control right from your iPhone or iPad. Depending on what you want to do, a hub will unlock more advanced functionality:' - and the list is remote access, automation, notifications, and Thread itself. The hub Eve names is an Apple one: 'HomePod (2nd gen), HomePod mini or Apple TV 4K (2nd gen/3rd gen 128 GB) will unlock all of these benefits', with older models qualified as 'If you only want to enjoy Remote Access, Automations and Notifications, HomePod (1st gen) and previous Apple TV models will also offer this functionality.' The requirements list is blunter still: 'Controlling this HomeKit-enabled accessory automatically and away from home requires a HomePod or an Apple TV (4th generation or later) as a home hub.' Eve also says what kind of Thread device this is, which matters if you're planning a Thread network: Eve Room is 'a Minimal Thread Device (MTD)', a battery-powered device that doesn't pass along other accessories' signals, unlike Eve's wall-powered products.) · Works offline: Not checked — we have not established whether this keeps working without the internet Full sourced profile for Eve Room Indoor Air Quality Monitor →

The three infrastructure patterns

Matter-over-Thread, or nothing. The Aqara Door & Window P2 ($29.99), Aqara Motion & Light P2 ($33.99), Eve Motion ($54.95), and Eve Door & Window ($43.95) all take the same deal. You get no proprietary hub, wide five-ecosystem support, and local control. In exchange, they depend completely on a Thread border router plus Matter controller. Aqara’s listing says a border router “is required”; Eve’s wording is the same. IKEA’s 2025 wave now undercuts them all on price with the identical architecture: the MYGGSPRAY motion sensor, MYGGBETT contact sensor, and TIMMERFLOTTE climate sensor are $11.99 each, with two asterisks straight from the records: the required rechargeable AAA batteries are sold separately, and IKEA’s product pages skip the numbers you’d want. Its manuals don’t. Re-verifying MYGGSPRAY and MYGGBETT turned up a stated battery life of about 15 months for each, plus a detail the listing omits — MYGGBETT is indoor-only. Detection range and angle for the motion sensor are still unpublished anywhere. If you own a HomePod mini, a Wi-Fi + Ethernet Apple TV 4K, a Nest Hub, a newer Echo, or IKEA’s own DIRIGERA, you already have the infrastructure and all seven are plug-in easy. If you don’t, add that cost before comparing prices — our Thread border router guide covers which boxes qualify.

Bridge-locked. The Philips Hue Motion sensor ($48.99) is Zigbee behind the Hue Bridge, with no Bluetooth fallback. Everything it offers to HomeKit, Alexa, and Google flows through the Bridge. In a house already running Hue lighting that’s a feature: motion-to-light automations execute on the Bridge locally, and the sensor reads temperature and lux besides. As your first Hue product, budget the Bridge on top of the sensor — and note the ceiling Signify states in the sensor’s own specification, a maximum of 12 accessories per Bridge.

Bluetooth now, hub later. SwitchBot inverts the Thread deal. The Contact Sensor ($16.99) and Meter Pro ($29.99) work out of the box over Bluetooth with your phone in range, and that may genuinely be enough for a “did the garage door close” use case. The upgrade path is where the money is: remote notifications, voice assistants, and Matter each require a SwitchBot hub, and Matter specifically requires Hub 2, Hub 3, or the Hub Mini Matter Enabled. Cheap to start, priced to expand.

The outlier is the Aqara Presence Sensor FP2 ($82.99): straight to 2.4 GHz WiFi, no hub of any kind, and also no Matter and constant USB-C power. It’s a different instrument, mmWave presence rather than PIR motion. It knows someone is sitting still on the sofa, which is precisely the scenario where every PIR sensor above times out and turns the lights off on you. Zone setup lives in the Aqara app and takes real effort.

Reading the table honestly

One record carries ”?” in the SmartThings column, and it’s there on purpose. The FP2 does not appear in Aqara’s official SmartThings documentation, so we record unknown, which is a verified statement about the documentation rather than a guess in either direction. Community integrations may exist; our table only asserts what a primary source supports. The SwitchBot Contact Sensor used to sit beside it and no longer does. SwitchBot publishes a support article saying the SmartThings app gets door open and close from this sensor, plus its battery level. The light sensor and motion detection stay out, which is why that row now reads partial.

One subscription flag in the whole category, and it is confirmed. The Meter Pro stores 68 days of readings on the device and two years in the app, and SwitchBot’s spec table for it says what happens after that: “Storage beyond 2 years requires a payment for continued use.” An earlier version of this paragraph told you that sentence had disappeared from SwitchBot’s site. It had not — it moved. The page we first read it on is gone, and the clause now sits in the specifications table on the US product page, where we re-read it in September 2026. SwitchBot still publishes no price for it, so what you know is that a charge exists, that it arrives two years in at the earliest, and that its size is SwitchBot’s to announce.

Alexa households should check the partial marks. The Aqara Motion & Light P2 loses its light-sensor half in Alexa (motion carries over Matter; lux doesn’t), and SwitchBot’s voice support routes through its hub with scene-level rather than device-level depth on some combinations. Full rows and caveats live on each product page.

For renters

This is quietly the most renter-friendly category in the library: twelve of the fifteen sensors here run on batteries and mount with adhesive, so move-out is a thumbnail job, not a spackle job. The FP2 and the Meross MS600 are the exceptions, and only in needing a wall outlet. The real renter math is the infrastructure: a border router is yours and moves with you, which makes the Thread sensors a portable investment in a way hardwired gear never is.

Where to start

Pick the infrastructure pattern that matches what you already own, then the sensor. Thread border router in the house: IKEA’s $11.99 trio is now the cheapest way in (batteries sold separately), the Aqara P2 pair publishes detection range and angle where IKEA still publishes neither, and Eve uses friendlier AAA and AA cells against Aqara’s coin cells, per the records. If the IKEA motion sensor is going outside, check its record first: IP67 covers water and dust, but IKEA’s own operating range stops at 0 °C. Hue Bridge household: the Hue Motion slots in with zero new accounts. No infrastructure and no plans: SwitchBot starts at $17 today, with the upgrade costs stated up front. Run your exact combination through the checker, or take the starter quiz if you’re still choosing an ecosystem.

Frequently asked questions

Do Matter sensors need a hub?

The Matter-over-Thread sensors in our library (both Aqara P2 models, both Eve models, and all three IKEA sensors) need two things: a Thread border router and a Matter controller, often the same box. A HomePod mini, a Wi-Fi + Ethernet Apple TV 4K, a Nest Hub (2nd gen), newer Echo devices, an Aqara Hub M100, or IKEA's DIRIGERA all qualify. Without one, these sensors do nothing at all — except the IKEA TIMMERFLOTTE's on-device display, which reads out temperature and humidity hubless.

Which sensors work without any hub?

A few, with limits. The Aqara Presence Sensor FP2 connects straight to 2.4 GHz WiFi and needs constant USB-C power. The SwitchBot Contact Sensor and Meter Pro work over Bluetooth with your phone nearby; remote alerts, voice assistants, and Matter all require adding a SwitchBot hub. And the IKEA TIMMERFLOTTE shows temperature and humidity on its own display at a button press — but app readings and automations need a Thread border router.

Why does the Aqara motion sensor show partial Alexa support?

Matter carries motion detection to every ecosystem, but Alexa drops the light-level half of the sensor, per Aqara's own documentation. If lux-based automations matter to you, that column is the difference between full and partial.

What do the question marks in the table mean?

They mean we checked and the official documentation doesn't answer the question. The FP2 has no official SmartThings listing, so we record 'unknown' rather than guessing. A ? is a verified gap, not missing homework.
