Does anyone know about a pre-build solution like this? #85

Sorry to open an issue for this simple question, but it seems discussions are not active on this GitHub project. I'd like to give this a try with my Bosch GC2200 W boiler, but I have zero skills for soldiering and electronics in general.

Is anyone aware of a place to buy this all pre-soldiered in a nice case ready to use? I am able to connect to it and flash new firmware versions, but anything concerning electronics and wires makes me hesitant.

Btw. I found some semifinished products with their own firmware solution, so the next question is, could your firmware be compatible with that hardware?

Are you sure your boiler supports opentherm? Bosch usually uses EMS bus.

Thanks a million. I relied on the vendor who claimed opentherm compatibility. Thanks to your hint, I dug deeper and figured out similar solutions for EMS Bus. I am renovating an old house in Eastern Europe and most of the time, all appliances including boilers seem to be specific models made for that region hence I am struggling to find manuals and detailed technical information most of the time.
