Xiaomi Aqara ZHA Home Assistant
This is how to use the Xiaomi Aqara Wireless Double Button without the Xiaomi Home Hub (A ZIGBEE STICK IS STILL REQUIRED) using ZHA in Home Assistant. Other devices just work without any hard to find IDs.
ADD DEVICE TO ZHA
Go to “Configuration”
Then “ZHA”
Hit “Add Devices”
Hold down left switch while lights are blinking until the left light blinks and stops
You can now name your button and hit the back button in the upper left hand corner
