Aqara Door and Window Sensor P2
Smart contact sensor for doors, windows and more (Thread / Matter)
The Aqara Door and Window Sensor P2 is a compact, battery‑powered contact sensor using Thread protocol to detect open/close status of doors, windows, drawers or cabinets. With Thread (Matter) compatibility, the sensor enables instant alerts, automations, and reliable home‑entry monitoring for smart home setups.
Reliable Door & Window Monitoring with Aqara Door and Window Sensor P2
The Aqara Door and Window Sensor P2 uses a high‑precision Hall contact sensor to detect when a door, window, drawer or cabinet opens or closes. Its Thread-based connection ensures stable communication and low power use, while battery operation keeps installation flexible and wire-free. It’s ideal for smart home security, child safety, energy‑saving automations, and monitoring access points.
How It Works
When the magnet unit moves away from (opens) or aligns with (closes) the sensor unit, the P2 registers the change and sends an update over Thread (Matter) to your smart hub or controller. This event can trigger scenes like turning on lights, sending push notifications, activating security systems, or logging activity in a smart home app.
