Change input source for HW-Q935B

I’m trying to figure out a way to switch the input source for Soundbar HW-Q935B via home assistant. Unfortunatelly no existing integration is working anymore (since Q4/2025)…
Seems like the api changed and a dedicated choice for the setInputSource is not existent anymore for this device.

I tried to work with the following commands, which gets confirmed, but nothing changes.

  • setNextInputSource
  • setSoundFrom
  • execute (didn’t find a match)
  • ocf (no idea how this could be set)

Any ideas or similar problems?
