Xiaomi Mi Door & Window Sensor 2

The Xiaomi Mi Door & Window Sensor 2 is a smart home security device that combines opening/closing detection with a built‑in light sensor, enabling more interactive automation scenes. It records every opening and closing event, sends real‑time push notifications to your phone, and even provides timeout reminders if a door or window remains open.

Using magnetic induction technology, the sensor accurately judges the open/close state. Once connected to a Bluetooth gateway, you can check the device status anytime, anywhere via the Mi Home/Xiaomi Home app. Compact and easy to install, it enhances home security while supporting smart automation with other Xiaomi devices.
