In the world of control logic, this sort of thing is needed a
whole lot.  One common way to go after this behaviour (the
temperature of the room determines whether the heater or the air
conditioner goes on, for instance) is to use Fuzzy Control Logic.

Python has a bunch of packages for doing this, but I haven't ever used
them, so cannot comment on how good any of them are.
