I have a group in my house called group.house which has a Sonos and a Google Home in.
I want to use the TTS to these but have them play at the same time. At the minute it does one at a time.
Is it possible to play these at the same time? I plan on adding more devices and would like messages sent to all at the same time instead of one after another.
I don’t have Sonos, but can you group them together in the Google Home app? If so, then you should be able to use THAT group as opposed to the one you created in HA. AFAIK, the Home app can only group Homes and Chromecast Audios together as an audio group but since I don’t own any Sonos product I’m not sure if this includes Sonos.
