3 day average for outside or weather data.

Don't really understand the thought here. In UK temperature quite unstable. I would have thought a forecast option may be useful or possibly 1 day & 1 night.

That's the problem....

I put on 3 BT for fun and set the different temps, 12 °C, 15 °C and 17 °C.

The coldest time is between 5 a.m. and 7 a.m., when the temperature falls below the temperature there, BT switches to heating, even if the sun is beating down in the afternoon, no matter how many °C.

Therefore, it is best to use the weather value from the forecast and use the outside sensor to switch off like the window contact, so the whole function is useless.

Agree. Matters made worse by using a 3 day average. Its poor to start hacking a nice integration but you can use a threshold helper as an on off switch and like you said add it as a window open input. Using the forecast or actual outside temperature value, I read somewhere, may work in a future release to introduce a "feels like" offset.

I also don't understand this. The past doesn't really matter for heating in the future.

I think to use a forecast is way better. Something like. Now it's cold and BT would switch to heat, but in 3h the temperature is above the threshold so we don't heat now.

Any other suggestions? That's something I would implement.
