Aqara Motion and Light Sensor P2

Compiled by SmartHomeWorkflow Research · Aqara · Sensors & Detectors · ~$33.99 ($33.99 read from Aqara's own store structured offer data on 2026-08-08 (SKU DTC-US-SN-MLSP2), single unit, in stock. 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.)

Compatibility

EcosystemSupportThe catch
Amazon AlexaPartialPartial support — see the catch[13]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.In Amazon Alexa you also need: a Matter-capable Amazon Echo or eero device — Alexa’s rule for every Matter accessory.

Google HomeWorksWorks with this ecosystem[13]Via Matter over Thread — requires a Google Thread border router (e.g., Nest Hub 2nd gen) as the controller.In Google Home you also need: a hub for Google Home (a Nest speaker or display, Nest Wifi Pro, the Google TV Streamer, or a compatible TV) — Google Home’s rule for every Matter accessory. Source (read 2026-09-11)
Apple HomeWorksWorks with this ecosystem[13]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.In Apple Home you also need: an Apple home hub (a HomePod, HomePod mini, or Apple TV) — Apple Home’s rule for every Matter accessory. Source (read 2026-09-06)
SmartThingsWorksWorks with this ecosystem[13]Via Matter over Thread — requires a SmartThings hub with Thread border router capability (Station, Hub v3, Aeotec).
Home AssistantWorksWorks with this ecosystem[13]Officially listed by Aqara; joins through Home Assistant's Matter integration, which needs the Matter server add-on plus a Thread border router.In Home Assistant you also need: Home Assistant's own Matter Server app, installed from inside Home Assistant (no extra hardware to buy) — Home Assistant’s rule for every Matter accessory.

Protocols: THREAD · MATTER[1][2][3][5][10]

Needs before it works: 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. No Aqara hub required — but adding an Aqara Hub M3 unlocks custom detection timeout, sensitivity tuning, and local alerts via Aqara Home.[2]

What it can do[9]

You can tell it to

Not established — we could not confirm this from vendor documentation

It reports

  • Motion detected

Whether each platform's automations and routines can use it — not just whether its app shows it.

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality[16]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

Maintenance reality

The catch

Nothing works without both a Thread border router and a Matter controller, and feature depth varies by ecosystem — Alexa drops the light sensor, and tuning sensitivity or detection timeout requires adding an Aqara hub.

Who it's for

Suits households that already run a Thread border router (HomePod, a Wi-Fi + Ethernet Apple TV 4K, Nest Hub, newer Echo, or SmartThings hub) and want a battery-powered, locally controlled motion-plus-illuminance trigger without an Aqara hub.

The catalogue is split on this (8 of 28 Matter-over-Thread records list bluetooth, 20 do not) and has no documented rule; the raw certificate field is recorded here so the evidence survives whichever way the rule lands. Warranty: https://us.aqara.com/pages/limited-warranty — Aqara's published warranty table gives 'Smart Home Sensor 12 Months'. ⚠ Recorded with its limitation rather than as a flat 12-month promise: the same page states the warranty covers 'purchases on us.aqara.com' and excludes 'Items purchased from sources other than us.aqara.com', so a unit bought from a retailer is not covered by this term. — Read on the maker's own site, verified 2026-08-08
