Hi found this repo because I'm looking into controlling my Pellet Stove from Jolly Mec (using a Micronova board) using ESPHome. Does your project work ? Can you please share some details on the wiring and physical setup you are using ? Thank you.

I've used this schema from @philibertc image

Thank you. This uses an Enable_RX pin but I don't see how you are using this in your code (yml or .h). Is the main branch currently working ? I see you made recent commits so maybe this is just work in progress. I might be able to contribute.

Now I no longer have that stove but I can confirm that it worked, unfortunately I can't find the board I used, as soon as I find it I'll post the photos. I've updated the YAML and .h cause I found it was old comparing what I have on my homeassistant.
