ZHA broken after .115.1 update

Configuration
1

I’m running HA in docker with a CC2531 USB stick forwarded into the container. Zigbee was working fine on the latest .114 release but all devices are showing as unavailable after the .115 upgrade

In my logs I’ve got

Logger: zigpy.application
Source: /usr/local/lib/python3.8/site-packages/zigpy/application.py:67
First occurred: 9:35:07 (1 occurrences)

I was in the same situation. Funny because it seems home assistant could see the entities (as their last seen time was updating), but it couldn’t control them. I ended up reverting back to a 114 snapshot and had to remove and re-add some devices to get them working again.

Did you ever get 115 to work? I was thinking of investing in a conbee and trying that with zigbee2mqtt to see if that works.

It worked after applying the mitigation in another thread but after the recent point release update (I think) it’s now broken again. I’m now tempted to look at ZigBee2MQTT based option buy a sonoff ZigBee bridge because I’m starting to lose trust in HA ZHA stability (which’ll guarantee that everything gets fixed and is stable once the sonoff arrives).

I had this issue too (using the iTead CC2531 adapter). I deleted my Zigbee devices and repaired and they have been fine since. Not too bad for me as I only have 3 Zigbee door sensors connected to HA

I ended up buying the Sonoff zigbee bridge and set that up in ZHA using https://www.digiblur.com/2020/07/how-to-use-sonoff-zigbee-bridge-with.html

I figure since ZHA is connecting over TCP/IP it shouldn’t break if any zigbee changes are made to ZHA. Works well so far, we’ll see if it lasts.
