Premium quality and superb craftsmanship
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.
*The 2-year battery life was confirmed through testing by the Aqara Laboratory. Using standard CR1632 batteries, sensor opening and closing was simulated at a rate of 20 times per day, at an ambient temperature of 25°C. The battery life may vary depending on actual operating conditions. Under low-temperature conditions, battery performance will be reduced and battery life will be shortened.
Easy to install
1. Remove the protective film from the sticker.
2. Ensure that the installation mark on the side of the main body is aligned with the mark on the side of the magnet.
3. Attach the separate parts to the surface where it opens and closes. (The main body should be attached to the fixed surface of the opening/closing area, and the magnet should be attached to the moving surface of the opening/closing area. The gap at the point of installation must be less than 22 mm when the door/window is closed.)
*The adhesive surface must be kept clean and dry. To ensure the stability of wireless signals, do not attach the sensor to metal surfaces.
