MQTT Light / Switch Availability Topic Stopped Working

Configuration
1

Just updated to 0.63.1 (from 0.61.1) and my MQTT lights and switches are showing as unavailable when in fact they are all up and running and working fine. :

  • This was all working fine before updating.
  • The devices always publish their availability state using a retained message.
  • If I subscribe to any of these availability topics they are returning a value that represents “available”.
  • Some of these are in the lights domain and some in the switch domain.
  • If I manually reboot these devices or re-send the availability message via MQTT everything works fine.
  • After manually resolving the issue, if I then restart HA I have the same problem again.

I also have separate sensors that use the same MQTT topics and these all show the correct state:

It’s almost like HA is ignoring the retained messages on these topics. Any one else see this / having problems?

I’ve been chasing the same problem. I have 3 switches and it is hit or miss on how many of them will show up as available each time after HA restart.

I have raised this as an issue: https://github.com/home-assistant/home-assistant/issues/12485

Did you solve this issue? I have the same issue atm…

I disabled all of my availability configurations as I wasn’t really getting any benefit from them. This said, my MQTT sensors that subscribe to the same topics have been fine since updating to 0.64.
