excuse my bad polish but I live in Germany and use the google translator.
I bought a pellet heater with the PUMA PID and am very happy with it. Unfortunately, however, it is mandatory in Germany to have a buffer tank with at least 1000 liters when heating with pellets. But now it is the case that the PUMA PID always keeps the boiler at the right temperature and I do not want that. I'm looking for a way to turn off the PUMA PID without pulling the plug.
The protocol above, however, looks different than mine. A USB stick with the MAX485, Arduinos and Raspberry PI is available. I would be interested in a solution in Python here.
Thank you for your time
