Hello friends,
after having tried around for a long time and not finding a perfect solution for me, I have now built a very well working control for my living room heating. I have two windows in my living room and what was most important to me was that no matter which window is opened or closed, the heating is always turned on and off correctly. In addition, the temperature should be given from the thermostat to Home Assistant when the thermostat is changed manually and the values from Home Assistant to the thermostat, all according to the heating mode. I have now also solved everything about 1 mode from the thermostat, since the thermostat is controlled since some Home Assistant versions by the hvac_mode and a preset_mode. After a long time of trying I decided to use only heating and OFF from the thermostat and to define the Eco and heating mode directly in Home Assistant.
I think there are some solutions that are a bit simpler, because it’s all very complex and there’s no holiday mode. This is not so important to me because I switch the heating on and off manually when I come home from work and go to bed. More important to me was that the heating goes off when I open one or both windows.
Logic:
If one of the two windows is opened, it is checked whether the heating mode is set to Eco or Heating, if this is the case, the heating is switched off and the previous heating mode is written into a template. If one window is now closed and the other is still open, nothing happens. Only when both windows are closed will the system check whether the heating was previously in Eco or heating mode and then set it to the previous mode.
With the Xiaomi switch I can manually choose between the heating mode Eco and Heating. So when I go to bed I press the button and the heating goes into Eco mode. When I come home and press the switch, it goes on. Both, however, only if it was previously in either heating or Eco mode.
Devices:
1x Xiaomi Wireless Switch (for manual switching between eco and heating mode)
2x window sensors
1x Eurotronic Spirit Z-Wave Plus Thermostat
Home Assistant Objects:
2 sliders for the temperature setting of eco and heating mode
1 input selector for the thermostat modes (Off, Eco, Heating)
1 template input selector for the previous thermostat modes with window open
Setting options:
Off, Eco, Heating
Temperature for Eco Mode
Temperature for heating mode

It all works very well, but I would be very happy about suggestions and tips.
