Sonos playlists etc?

[homeauto2112]

With respect to point 2 & 3, you can set presets. The preset (whatevername.json) holds the speakers desired in a group, the volume level of each device and the name of the favorite station (Radio, Spotify, Apple Music etc).

With respect to point 3, can use a HTTP GET to start (shown in post number 18 above).

here are two other threads that I believe are orbiting a similar point.

Sonos Grouping

Can the Sonos driver/app be updated to support grouping of Sonos speakers?

Grouping Sonos speakers

I would like to put in a request to add Grouping of Sonos speakers. Like the Groups and Scenes app, could we get a Group that could group whichever sonos speakers we want in a set Group. I would like this for announcing arrivals and departures of family but I only want it to be on certain sonos speakers. And I would want it to resume playing whatever it was playing. Will this be possible at some point?
