Description
Keep your home secure and your automations running smoothly with the Sonoff Door Window Sensor R2 (Zigbee) a compact, second-generation contact sensor built for reliable open/close detection on any door, window, gate, or cabinet. Lightweight, discreet, and easy to install, it fits seamlessly into any home without affecting the look or operation of your doors and windows.
The sensor detects separation between the transmitter and magnet the moment a door or window opens, sending an immediate push notification to the eWeLink app. Stay informed in real time whether you’re at home or away.
If the sensor is forcibly removed or damaged, a tamper alert is instantly sent to your phone. You can also configure smart scenes to trigger a gateway alarm, activate a security camera, or set off a light giving you an active first line of defence.
Use it as a trigger in your smart home ecosystem. Link it to cameras to start recording when a door opens, activate alarms for security, or connect to climate control devices to adjust your home environment automatically when a window is opened or closed.
Supports both horizontal (30mm detection range) and vertical (15mm detection range) magnet placement, making it adaptable to wide gaps, narrow frames, and uneven door or window structures. The removable magnet design adds further installation flexibility.
Powered by two standard AAA batteries easy to replace anywhere in South Africa.
