Hey Leontin,
Awesome work btw, I pushed forward and made a PCB to tidy things up alittle, happy to share the file once I can prove it all works
When I try to flash the D1 Mini, I’m getting a schema issue error in ESPHome. Claude is suggesting it is due to ESPHome 2026.3.3 changes.
This is kind of above my level, but does your github need updating to reflect these changes and that is why its failing? Or is it something I can change my side?

(although there is no 12V there, but that's not really a problem as my ESP is a few meters away in the pool house with an external power supply).
I am gonna give it a try. Do you think that I should put an other resistor on the heat pump side as well ?
