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 in between.
Click the reset button of the Aqara Wireless Mini Switch. If the Aqara Hub makes voice prompts, "Normal link confirmed", it indicates that the Aqara Hub and the Wireless Mini Switch communicates properly.
Go to ②; If there is no voice prompt, please move the sensor closer to the Aqara Hub and try again. If there is still no voice prompt, the sensor might be deleted or run out of battery. Please refer to the accessory adding methods to add the accessory or replace the battery.
Single-click/double-click/long press the Aqara Wireless Mini Switch several times, enter the homepage of the Wireless Mini Switch in app. If the status is changed, it indicates the accessory works properly.
