How to connect Aqara Smart Lock U100 to your Home Assistant with matter
0
setup M1 hub with matter to HA
setup u100 in aqara app but not under the M1
setup HomeKit on u100
under m1 bind the lock to the hub
2 HomeKit instances. my homehub(Apple TV) is not close enough to my lock, so HomeKit only detects the state when my iPhone/iPad is in bluetooth range. I zigbee paired to Aqara hub m2 and then paired the hub via matter to HA, then made a HomeKit bridge to share the lock back into Apple home so that I can see the state updates on my Apple TV etc. then I just hid updates and status from the direct HomeKit connection.
