After aprox. 1,5 hours I took the power to the entire house, and after the bridges came on, the Outside Lights have most bulbs available again, but many sensors were not reachable.

Be sure to set Your bulbs to not turn on after powercycle |
So I went to work for 8 hours
When I cam came home, I took the power to the entire house, and after the bridges came on, aprox. 80% of the bulbs on Inside Lights were reachable - and all sensors seemed ok again.
In the evening I started to power off the power sources to the bulbs that was still unreachable, and slowly the came back in the app as reachable.

My conclusion is somewhat, that this possible was a software update - or similar - that kind of "broke" the bulbs (or bridge) ability to communicate - and software updates over Zigbee is slow and takes a long time. Point being: Dont panic to soon ans start resetting You bridge(s), have some patience and take the power off some times over a time period. Setting up everything again can take way longer time if You have many devices. |
