Use Bluetooth speaker as speaker

I’ve been trying to find out how to do multi room audio but not gotten past single room.

I don’t under stand why I can’t have home assistant play music, have it send that to a ESP that then connects to a Bluetooth speaker and plays it through that.

Home assistant (WiFi) to esp (WiFi), esp (Bluetooth) to Bluetooth speaker.

This would work GitHub - sle118/squeezelite-esp32: ESP32 Music streaming based on Squeezelite, with support for multi-room sync, AirPlay, Bluetooth, Hardware buttons, display and more

There is a community LMS addon.
