AQARA Door and Window Sensor
Due to its compact size, the Aqara Door and Window sensor is easy to use at a door, window or other entrance gate and transmits the open or closed status to the hub. This allows automations to be started or, for example, to report in an alarm situation. The Door and Window sensor has a replaceable CR1632 battery. This concerns the official European version with CE approval and meets the legal requirements.
