APlogies for my newbieness here. Just wandering into the path or multi room audio. I have a range of amazon speaker device, echo classics and dots and fire tvs… I know amazon has multiroom feature now but you need to be signed up for prime etc. With using home assistant, and i play local music say from plex or another library software on the server and stream this to zoned alexas in the house? Iv e been reading quite a bit, refering to using alexa in home automation and this video https://www.youtube.com/watch?v=DbQcFgEA7hw but i cant seem to find anything relating to multi zone streaming with home assistant to alexas.
