@badisensors I have this same issue and am struggling to find a consice answer to the question. Have you figured it out?
I would love to see a bit more detail about the important naming and numbering protocals for Gateways, Nodes, Sensors, and their output values within the MySensors architecture. So far, I am not finding much and progress is slow when I simply need to try different iterations and make conclusions/adjustments.
hey,
sorry for late reply. PR for mysensors is ready to be merged:
https://github.com/mysensors/MySensors/pull/1570
next step is create PR in mysensors integration for home assistant.
Best regards
Mariusz
Figured it out. I had to send HVAC_FLOW_STATE to HA, in order for it to figure out that it was a "thermostat". Only problem is that it shows up with states "Auto" "Cool" "Heat" and "Off" in the dashboard, even though I only have the possibility to heat, or turn it off.
