Allow a range of temperatures for a schedule (e.g. "comfort enough")
Add an ability to define temperature in a schedule as an acceptable range.
E.g. in the morning heat to 20C if it's lower than 19C.
This could be useful in many scenarios.
For example, your room is already at 19.5C, and the schedule says 20C.
There's no need to run the boiler to heat it for 0.5C more.
Especially if it's a heated floor (or any other slow heating) and it takes about an hour to heat to the needed temperature (0.5C more!).
I could live with 19.5C just fine.
