Looking for a self-hosted home audio system, something like Sonos where you can play music in different zones/rooms and control it from a phone or tablet. Not sure on speakers, maybe something running off of raspberry pi’s or just standalone speakers if that would work. Anyone doing something like this?
I can recommend mopidy and snapcast.
This will allow for a Sonos like setup you are looking for.
Snapcast works incredibly well for multi-device audio.
Has anyone tried setting up multiple zones with it that can play different things at the same time? I imagine you would need one snapcast server per zone? And is there an easy way to assign the clients to one of the servers?
You can configure multiple zones on a server snap with multiple hosts
A client can assign to one host only.
This looks really cool. Any recommendations on clients(speakers)? I have a couple of older raspberry pies I could use if as remote speakers, but I'd need a few more.
Personally I use Raspi 2 and Zero for that purpose. HATS for digital connection or if you want connecting speakers directly consider AMP2 HAT.
Homeassistant controls grouping, volume etc.
