Our take
The Door and Window Sensor P2 is Aqara's Matter-over-Thread contact sensor for detecting whether a door or window is open or closed. It adds a remote alarm feature and supports local automations, and connects directly to Apple Home, Google Home, and Alexa without the Aqara hub. Like the motion P2, it needs a Thread border router to function.
What we like
- Direct Matter over Thread connectivity, no proprietary hub required
- Remote alarm and local automation support
- Compact design that fits most door and window frames
- Long battery life on a coin cell
What to keep in mind
- Requires a Thread border router, which not every household has
- Adhesive mounting can struggle on textured or uneven surfaces over time
- No built-in tamper or vibration sensing beyond open/close
