Sonoff White Wifi Wireless Home Sensor for Doors and Windows

Monitor your property at any time

With the Sonoff Sensor, you can monitor your property or household at any time. The sensor will be triggered when the attached door or window is opened or closed, sending over a notification to your phone.  You can check real-time opening and closing status through the eWeLink APP. 

*Please note that for sensor notifications the Sonoff RF-Bridge or other Gateways that use EV1527 will be required. 

Ultra-efficient battery lasts up to 2 years

The Sonoff Sensor has a low energy consumption and the battery can last up to two years. The Sensor also features a real-time battery level display and a low battery reminder to ensure you are aware of when the sensor batteries require a replacement. 

*Please note that the sensor requires an MN27 battery which is not included.

"Ask" to check the device status via Google Home or Alexa

With the Sonoff Sensor you have the option to heck the status of an open or closed window or door through your Google Home or Alexa instead of solely your mobile device. 

Check history records

Easily check sensor trigger history records from the last 3 months via your phone. 

Share with others

Share your sensor status with others for added security. This way your entire household can have peace of mind and access to security notifications. 

Easy to install

With a simple peel-and-stick installation process, the sensor can easily be fitted into both door frames and window sills, as long as the sensor and magnet are aligned and the gap is less than 5mm.
