How to get Vallox 510 SC smart?

Hello, as a newbee, I try to get my ventilation unit smart. It’s a Vallox 510 SC.


As you can see in the picture, there is a 4-level-switch (SC 0-10V) and a Switch for the bypass for the heat exchanger (MK).

Is there anyone who had the same project? Anyone who had a solution?

Thanks for your help!
