I just replaced my Nest gen 2 thermostats with gen 4 ones.
Firstly they are large, ugly, obnoxious. Get a gen 3 if you can.
Secondly, there is no early-on setting, starting to heat based on room and outside temps to get it to the desired tempo by the scheduled time. Maybe it is covered by Net sense - Smart schedule, But that is not explicitly stated.
Any ideas?
