It would be cool to see Roon working with Brilliant control panels. They currently only support Sonos.
Similar to the Control4 integration, I would assume if it was supported it would only be on Nucleus. .
100% agree this would be a nice additional feature for Roon. Not sure why it would require a Nucleus though.
Perhaps you could suggest to Brilliant that they use the published Roon API to integrate Roon into Brilliant?
Similar to what has been done for the Home Assistant ecosystem.
