I hate to add what might be useless information to an already long thread, but I was following the guide posted here to add this lock to HA using the M2 Hub via Matter and something curious happened.
When I went to bind my door lock to the Aqara M2 Hub over zigbee it would fail over and over and then I remembered that my I accidentally left my zigbee2mqtt on “Permit Join All”, so I went and looked and sure enough the lock was binding itself to my existing zigbee network via z2m instead of to the Aqara hub.
Now it says “unsupported” in z2m, but I’ve been able to add support for other zigbee devices that z2m said weren’t supported fairly easily. Did I stumble onto something that would be useful for this device or has someone already been down this road?
[Edit] Looks like this is already known according to this thread on z2m, I just didn’t have to cut the power to my device when it started pairing for it to prefer my z2m zigbee network over the hub. Will keep following for more updates
