Thanks for all the amazing feedback!

I think the first step is to fix the front panel and IR, because why not. Then it should work and I can install it. Might need you help @Madskp and yes I’m danish.

But I’m really intrigued by the idea of making a streamer which can communicated directly with the speaker over ML. I quickly ask Gemini if this could be possible with an ESP32, and the answer was yes. It suggest using the spotify connect API for the music streaming. I would prefer an home assistant integration so I could use music assistant, which I currently use with google chromecast audios. Thought the ML Interface the ESP should be able to select input and set volume. ESP would use the data pins to send so called “telegram” commends to the speaker. These commands are in a hex format. Although a voltage regulator is needed to take the ESPs 5v to 15v, which is the ML trigger voltage. The actual audio is sent analog. The ESP should be able to provide a high enough audio quality. For me this sound like the best option to “modernize” the speaker and others.

Also when searching using Gemini, I found out that the trigger volts with MCL should be 7v and not 5v. Don’t know if others have tried that.

I have seen these Almando device, but never tried them, maybe one day. But good to know that the TIMER function was what Almando used, if i go down the ESP32 route.
