Today I took the task to bring my Homebridge/Phoscon/Conbee-II combo to Raspbian bullseye (latest Homebridge-Raspbian Distribution).
Within this task, I upgraded my Conbee-II Firmware to 26780700 and the Phoscon-App to 2.24.1 - so far so good.
I have now the issue, that my Tradfri Switches aren’t working properly. As soon I connect them, they will change the status of all connected lights at once, but within Phoscon only - no light is actually turned on or off.
I’m able to set the switch up though directly in Phoscon with the “Switch Editor”, but nothing here is handed through to Homebridge/Apple Home anymore. Setup in the Apple Home App will have no effect.
And even if the setup is done within the switch editor, in the background the status of all connected lights will change, but then the configured ones will really turn on.
I verfied this with another fresh install → Same behavior. Also tested a brand new Tradfri Switch → Same behavior.
