What I did not try but might work: copy your persistence file, delete the old GW and create a new one with the persistence file you copied. Maybe the devices are preserved like this. Maybe you should create a full backup before...

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.
Hi,
Thank for your reply. Yes, i run since many years with a serial Gateway connected with my PI.
I thought it was possible to use the same machine to remove this extra element.
If you had a stability issue, I would just stick with my current formula and not change everything for now.
Regards,
