Smart Wireless Door/Window Sensor Sonoff DW2 WiFi

SONOFF smart door/window sensor, Wi-Fi

The SONOFF smart home system allows you to control your electrical appliances remotely with the eWeLink app or by voice with Amazon Alexa or Google Home. It allows you to create different scenarios, group appliances by switching multiple devices on or off with a single touch, set timers and schedules, monitor the status of your devices in real time, and share their control. Link your eWeLink account with the IFTTT application to extend your scene capabilities. Thanks to configurable local LAN support, the Sonoff smart home system can work without a cloud server.
