Hey there, thanks a lot. Sonos offers a rather extensive API (https://developer.sonos.com/reference/control-api/) which is also available in an Home Assistant Integration (https://www.home-assistant.io/integrations/sonos/) if that helps. In case the audio and input are accessed via API it might not be too complicated to implement especially night mode and speech enhancement?
That's what I'm looking for really. I've had another soundbar prior to the Sonos and could do basically everything from the remote so I was slightly surprised that Sonos has an entirely different philosophy.
