Hi
I recently found a site www.husdata.se that sells parts to watch and integrate heatpumps, I was happy to see that they even sell a dedicated communications board that you are supposed to attach to a PI and that sends the values over mqtt to your broker. Feels a bit overpowered to use a PI for that but I'm no programmer... throwing the idea out here and hoping that someone else might feel like making it compatible with ESPEasy instead! They have dev. manual located here: http://www.husdata.se/Download/o309fq2j ... 017.01.pdf
Looking at the image of the part it seems that the only connectors that are soldered are 5v, gnd and GPIO14/15
