I have a multi-zone amp that I have integrated with HA (https://github.com/sprocket-9/hacs-nuvo-serial/). It has a Chromecast on one of the inputs. I also have Google Assistant integrated with voice commands. The issue I am having is I can start music playing with “OK google, play blah on the whole home speaker” with “whole home speaker” being the Chromecast. I then have to go into HA and turn on the zone I want to listen too. If I tell google to play music to the media_player entity of the zone, I get an error (thinking because there is no input defined)
My thinking is to create an entity that has bits and pieces of the amps entity that contains the source and the zone entity that has on/off/volume/etc. Not finding much on how to make this work, or if it’s even the right approach. Ideally I want to say “OK google, play blah in zone1”.
Thanks…
