Sonoff Door Window Sensor

Sonoff Door Window Sensor

The Sonoff door window Sensor works with the Sonoff RF Bridge 433. The sensor is battery powered and does not require any physical cabling. This device sends open only alerts to the app via the RF Bridge, but does not support pull status. This product requires the Sonoff  RF Bridge to work. It can trigger your smart home scenes automating your light as you open the door.

Compatible with IFTTT function, the sensor can communicate with all compatible devices and services, to trigger them on or off. Easy to follow steps to access your smart home. The share control provides you a quick way to allow you and your family to control devices together. You can just take your phone out and open the app to check if your alarm was triggered.
