Music Experience Protocol
Sendspin is an open audio streaming protocol by the Open Home Foundation that delivers lossless, time-synchronized music to any device on your network. Unlike Chromecast or AirPlay, it's fully local — no cloud, no account, no latency surprises. The protocol handles sample-accurate multi-room sync so every speaker, headphones, and soundbar in your home or office plays in perfect unison.
sendspin-audio.comYour Music, Your Rules
Music Assistant is a free, open-source music library manager and streamer that unifies Spotify, YouTube Music, Tidal, local files, and 20+ sources into one interface. It connects to Chromecast, Sonos, AirPlay, DLNA, Sendspin — and now your Bluetooth speakers, headphones, and soundbars via this bridge. Runs as a Home Assistant addon or standalone. Your library, every player, one dashboard.
music-assistant.ioAutomate Everything — Including Your Music
Home Assistant is the world's #1 open-source smart home platform with 2500+ integrations.

"Hey Assist, play jazz in the kitchen" — and your $20 Bluetooth speaker, headphones, or soundbar responds.
home-assistant.ioHome Assistant's Assist brings conversational AI to your home — entirely local or cloud-enhanced.
