Unfortunately the api doesn't allow for that, or else none of this would be necessery.

The api has more features than the HA integration but doesn't go as far as that.

HA intergrations are just a shell around apis but as its laborious, they only include the features that the maker of the integration has translated from the API.

Actually, just looked at the API and you can't change open window detection mode from there. I wonder though if you could just read the mode (manual/scheduled etc) prior to the offset change and then reset that afterwards, would that override the open window detection, I think so.

Does anybody have the issue that this does not work when a room as more than one thermostat? The script works fine on one thermostat for me, but for rooms with more than one, the offset is not set.

I certainly didn't write/amalgamate this with that in mind. How were you envisioning it should work? When temperature readings differ between two thermometers, which one should be read? I'm not planning on maintaining this much further as I'm not planning on using it myself this winter. I've added right angle extensions to my radiator valves to move them further away and unfortunately I have a very busy job that has absolutely nothing to do with coding and am very amateur, so this takes much more time for me to fix than I have available and compared to how long it might take others.
