We have just released a new Git repository
(GitHub - RASPIAUDIO/esphomeLuxeMusic).
esphomeLuxeMusic is a new player based on the SendSpin protocol, enabling synchronized multiroom playback.
(SendSpin is specific to Music Assistant.)
This is a first attempt and is intended to evolve (we welcome your feedback here).
You can:
either compile it directly from luxe_music.yaml (note: requires esphome version 3.1.4+)
or load the binary directly from raspiaudio.github.io
(Special thanks to Deco for his crucial contribution)
