The Xiaomi Mi Window and Door Sensor features a compact yet sophisticated design for a wide range of applications. It detects any open or closed doors or windows in your home, is compatible with Mi Smart devices, uses ZigBee gateway technology and can be Smart Linked through the Mi Smart Home Hub.

The Xiaomi Mi Window and Door Sensor allows you to monitor when the windows, doors and even some furniture are opening and closing. The window and door sensor includes the main sensor body and a magnet, which work together to determine whether the window or door is open or closed. A notification can be sent to your mobile via the Xiaomi Home App whenever a door or window opens.

Combine with other Mi Smart Home devices and discover a variety of ways to utilize your smart devices. Use your imagination to customize your smart home experience. You could open the front door and your living room lights turn on automatically, or your air purifier could switch off automatically when you open a window or vice versa.

When combined with the Mi Smart Home Hub in Security Mode, opening the window/door triggers the camera to record a short video and send a push notification to your phone. The sensor connects wirelessly to other devices using ZigBee gateway technology, for fast and reliable connectivity. The batteries can last up to 2 years under normal conditions.
