Additional context Unable to have half of Temps, e.g. 20.5 set the temp to 21, 21.5 set to 22, etc... Maybe related?

Can you upgrade to 2.2.0 and try the command in the Console? su and then call thermostat temp 19.5. If that works then the problem is in your HA code.

Hello... Discovered that in heating mode, we can't go under 19 degrees on the thermostat... Sorry
