Track the status of doors and windows directly in eWeLink. When opened or closed, a notification arrives instantly, so you stay informed about what’s happening at home even remotely. There is also alerting for unauthorized tampering with the sensor.
Connect the sensor with other smart home devices and trigger automations—for example, a security scenario when a door/window opens, or energy-saving functions such as turning off the thermostat when a window is open or switching off lights after a door is closed.
A detachable magnet and both vertical and horizontal mounting make it easy to attach to different types of doors and windows. The PC housing is UV-resistant, and the device has passed drop and thermal-shock tests for more reliable indoor operation.
Sonoff SNZB-04PR2 reliably monitors whether a door or window is open or closed. You can see the status in the app and receive real-time notifications when it changes. The practical tamper function provides an alert if someone attempts to remove the sensor or manipulate it without authorization.
Thanks to the Zigbee 3.0 standard, the sensor integrates easily into a smart home and enables automations—from security scenes (triggering a camera/siren on opening) to energy-saving modes (turning off heating when a window is open). The detachable magnet and both horizontal and vertical mounting simplify installation on standard as well as less common surfaces.
