Aqara Door and Window Sensor P2
Added Dec 1, 2025
About
The Aqara Door and Window Sensor P2 is a compact Thread-enabled contact sensor that detects whether doors, windows, or cabinets are open or closed. Its Thread radio enables direct communication with Thread border routers like Apple HomePod or Home Assistant Yellow, bypassing the need for an Aqara hub.
With Matter support over Thread, the P2 works locally with any Matter-compatible controller without cloud dependencies. The Aqara Home app adds cloud-based features like remote notifications and automation history, but the sensor functions fully offline through HomeKit or Home Assistant.
The sensor is extremely compact at just 33mm × 24mm × 8.5mm, uses a CR1632 battery lasting up to 5 years, and includes an accelerometer for tilt detection in addition to the magnetic reed switch.
