rooms that play together.
Room-first multiroom speakers: Raspberry Pi Zero 2 W + HiFiBerry boxes that each run their own room with Spotify Connect and AirPlay, then group themselves into a whole-house system. Surface exciters instead of cones.
highlights
- room-first: every box is its own room, out of the box
- autonomous grouping — hubs are elected, dead hubs fade back
- stereo pairing per box via snapweb
- captive-portal setup on first boot
