Any solution to this? I read somewhere that it is still possible to use voice commands to switch input and adjust volume. But apparently only in English. That’s kind of a dealbreaker in my house…
You can override the device_class in customize.yaml (also possible from the UI somehow):
media_player.living_room_tv:
device_class: tv
However I cannot for the life of me get volume control working from Google this way. On the Google Home Hub / Nest Hub there are even volume +/- buttons for the device and they do not work either (they do work for my other non-smartir devices). Volume control works fine from the media player card in HA and by calling media_player.volume_up etc… so I think it has to do with smartir
