Not sure what a music assistant is. The speaker acts like a media player in Home Assistant. Actually now that I think about it, I don't know how I'd play music on it. It doesn't seem to do cast. 🤭

It does! I have my bedroom one controlled through it and even showing up as a play target for Spotify Connect. I've got my speakers I was plugging into my phone to play music before, or into a Raspi briefly, plugged into the 3.5mm jack on that one.

My kitchen one I just leave as-is. I DID modify the ESPHome firmware on each, extending to add an OLED (I think) clock display that also shows remaining time for timers in numbers. I do really like the LED ring animation for timers built-in though, it's pretty slick!
