i was searching the internet and the forum, but I did not find a solution.
I would like to create a thermostat to control my heatpump which in fact has a heating and a cooling mode.
I would like to set 2 target temperatures (one for heating, one or cooling mode).
So for example heating is 21°C +/- 0,5K and cooling is 24°C +/- 0,5K
So depending on the temperatures the heating or cooling mode should be used. Between 21,5°C and 23,5°C there shall be either heating or cooling.
How could this be solved ? Or is there a way to create two generic thermostats (one for heat, one for cool) and then to control them with one frontend card?
You might be searching the wrong terms. I think you want to search for auto switching thermostat.
I use a GoControl GC-TBZ48 Z-Wave thermostat. I think that one is no longer made. They probably make a newer version.
It has a couple of great options. One, Z-Wave. So, can be controlled with HA. Two, it can use a remote sensor. I use an Aqara Temperature sensor in the living area. The thermostat is in the hall and wasn’t keeping us comfortable.
This video shows a clear way on how to heat & cool when you have a single “on” & “off” switch. The video is in Spanish but the commands to be written are clearly shown.
