I've had this 3rd generation Nest for almost 2 years. This thermostat does not work according to schedules, the home- away functions don't work. Regardless of the schedule I use the thermostat overrides according to its own determination. Even when I was away from home I had the thermostat set to away and I found out that for some reason the heat mode just simply was turned off. I would really recommend looking at an ecobee model. Plus ecobee support is much more helpful.
