Okay, so my engineer brain went down a rabbit hole….

There was at some point something called an ML Gateway, which allowed you to control ML device via the network. Sort of Beo intelligens but earlier. To add to this someone as made an Home Assistant (HASIO) integration, which allows you to control it via HASIO. This could be way cooler than my Chromecast audio streamer with some weird cable solution that might not work…..Also I do use HASIO so…  I Have attached the ML gateway Installation guide and here is the HASIO integration 

Also Someone has made a hat for a raspberry pi for controlling ML/MCL device. They also have some documentation for how the data signals look like. Check this link.

With this in mind, it could be possible to make a streamer which and wake and play music on the beolab 3500 using an ESP32. NICE!

I’m unfortunately not good at programming, so I might start with looking at the ML Gateway.

Hi,

Thank you for your feedback. I will definitely take a look at your thread in detail.

It sounds weird that you can trigger it though the ML or MCL ports, since that’s how other B&O products talk to it. Especially since it doesn’t have a build in source player.

I have read that many of these trigger+RCA to DIN doesn’t work with the BeoLab 5, but think that’s because of its internal dsp. Which the BeoLab 3500 doesn’t really have. So again, why wouldn’t it work??

Do you by any chance have the pin out documentation for the ports on the BeoLab 3500? Might try with an esp32 dev board.

I now wonder if my beocenter 9000 can talk to it, but it doesn’t have ML or MCL. It does have link capability via the Beolink (type 2046) box and datalink, which I have. Also the beolink does say MCL 2A on it. Since both devices was able around the same time period, one would think.

Otherwise I might need a new front panel on my BeoLab 3500. Or maybe the IR eye can be connected?

Again thanks for the feedback.
