Sidehistorik
I experienced that today - late at night, I was unable to control all lights (I have 116 devices), and my 2 Hue bridges (Inside Lights and Outside Lights) all showed this:

Update 5 days later from the original issue occurred - One Hue brigde (Outside Lights) has all bulbs and sensors as unreachable again, the other (Inside Lights) is fine. Tried to power of the bridge and the power to some bulbs, with absolutely no effect. Even almost stranger, I can see that the sensors on the brige became unavailable in Home Assistant over a period of time, its not like just - all unavailable suddenly at the same time ... I have disabled Software updates for both bridges. So, this afternoon I tried to change channel - no improvements. Then I power cycled the entire house, and now 4 sensors is back (2 motion, 2 window/door), the rest is still unreacable. . See below |
The bridges seemed fine, and I (beside panic) started to investigate:

My conclusion is somewhat, that this problably was a software update - or similar - that kind of "broke" the bulbs ability to communicate - and software updates over Zigbee is slow and takes a long time. Point being: Dont panic to soon and start resetting your 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. |

So I took down the 3 "Terasse" bulbs
I could not reset them in their outdoor socket (10 sec with the dimmer) - went fine inside
All 3 were reset, deleted in the app and rediscovered
So I took down the 3 "Front Door" bulbs
2 of them just worked inside instantly
The 3rd needed a reset, dould only be rediscovered via serial number...
So, now I am even more confused.....
