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

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]

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

Subscription reality

✓ Works without a subscription: Yes.

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

Maintenance reality

• Batteries: CR2450 x2 — expect roughly 24 months per set
• Works without the internet: Yes — the core function runs on the device or your home network. A vendor cloud may still be involved in remote access.^[7]
• Batteries included; Aqara rates life at up to 2 years. Matter-over-Thread automations run locally through the controller.
• Security updates: Aqara declares security updates for this model until December 31, 2026 (UK-declared — the maker's legal commitment is filed for the United Kingdom). After that date the product keeps working; the manufacturer simply has no stated obligation to keep issuing security fixes.^[8]

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.

Radios from https://csa-iot.org/csa_product/motion-and-light-sensor-p2/ — certificate CSA22084MAT40084-24, certified 2022-11-03, Specification Version 1.0, Vendor ID 0x115F, Product ID 0x2003, and **Transport Interface: 'Thread, Bluetooth'**. ⚠ The Bluetooth in that field is COMMISSIONING transport for a Matter-over-Thread device, not a control path, so it is deliberately not added to this record's protocols — the same call made for the Tapo L535E on 2026-08-08. 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. — vendor-page and certification-registry research, verified 2026-08-08
