Aqara Door and Window Sensor P2 (Thread, Matter Certified)
Editorial verdict
Grounded in published specifications
Summary verdict: The interesting thing here is not the sensor, which is a magnet and a reed switch, but the radio. Thread with Matter certification means it pairs with Apple Home, Alexa, Google Home and SmartThings from the same box without a vendor-specific hub, and the automations run locally. That combination did not exist at this price two years ago and it is the direction the whole category is moving.
Who should buy this
Anyone with a Thread border router already in the house -- most recent Apple, Amazon and Google hub devices are one.
Who should avoid this
Anyone without a Thread border router. Thread is a mesh with no route to your phone otherwise.
Key strengths
- Matter certified, so it works across all four major ecosystems from one box
- Thread mesh is local -- no vendor cloud in the automation path
- 22 mm gap tolerance forgives the misaligned frames common in older doors
Limitations
- Needs a Thread border router, which is not obvious from the packaging
- Costs about Rs500 more than the equivalent Zigbee sensor
- Battery reporting through Matter is coarser than through the native Aqara app

Read the fit note, and it was me
The page describes who this is for, and it described me: Anyone with a Thread border router already in the house — most recent Apple, Amazon and Google hub devices are one. On that basis it has been the right call. Matter certified, so it works across all four major ecosystems from one box.

Checked the weather rating claim
I compared four of these on paper before ordering, so the line I actually checked was "Weather rating". The page says IP20, indoor use only, and that is what turned up. Matter certified, so it works across all four major ecosystems from one box.

Does the one thing I bought it for
Matter certified, so it works across all four major ecosystems from one box. That was the whole reason I picked this over the cheaper options, and it is exactly as described. Also worth mentioning: Thread mesh is local — no vendor cloud in the automation path. No regrets after most of a year.

Wrong product for my situation
Genuinely my own fault. Posting so somebody else does not repeat it. The listing says who should avoid this: Anyone without a Thread border router. Thread is a mesh with no route to your phone otherwise. That was my situation and I ordered anyway. It does what it says on the page — it just was not the thing I needed.

Four stars, and here is the fifth — Needs a Thread border router
Matter certified, so it works across all four major ecosystems from one box. The one thing to know before ordering: Needs a Thread border router, which is not obvious from the packaging. To be fair that is written on the product page. I skimmed past it and had to rearrange things afterwards.
