It supports single press, double press, and long press. It can control other Aqara devices with different actions.

The Aqara Wireless Mini Switch can either be attached to the wall or placed on a table. Installation on a metal door is not recommended because metal surfaces affect the signal. When being used as a doorbell, the wireless switch can be installed on the wall next to a metal door. Please refer to the quick start guide for more details.

The indoor environment varies, and maximum signal strength between the Aqara Hub and the Aqara Wireless Mini Switch is different. There should not be more than two walls between them.
