Aqara Door & Window Sensor

Aqara Window & Door Sensor informs you when a window or door has been opened in your home. If this happens, the sensor will immediately send a notification to your smartphone to alert you. With the help of adhesive, you can easily install it wherever you want in your home. Aqara Window & Door Sensor has a battery life of 2 years, so you don't have to worry about frequently changing batteries.

The international version works just like the regular version but may require setting the region as China Mainland on Aqara's own control units.
