Discover how it works

This smart Wi-Fi door/window sensor sends a notification to your smartphone when a window/door opens or closes. Alternatively, you can use the app to see if you forgot to close a window. All you need is this sensor, the Smart me app and a stable Wi-Fi network to get started. In the Smart me app, link this Smart me sensor to one of our smart Wi-Fi LED light bulbs and you can automatically turn it on/off when the sensor detects movement. This sensor comes with a battery and adhesive strips and is therefore easy to place on any window/door. It's plug and play!
