[ENHANCEMENT]: add outside and inside temperature to scheduler conditions

[MikeyMan83]

The cool function is quite rudimentary. Would like to have some more control. One easy way would be to add conditions to turning cool mode on, based on inside and/or outside temperature sensor.

Could be added to the existing conditions in the scheduler. For instance:
Only turn cool mode on when outside temperature is above 25 degrees and inside temperature is above 22 degrees.

Alternatively a re write of the cool function could be an option. But much more time consuming. Needs more thinking.
