An ecobee isn't designed to stay at the exact perfect temperature you want your house to be. It forces you to experience a range of temperatures that dance around your comfort zone. That's what the people want right? Almost comfort? The longer I have it, the more I regret buying it. I'm getting pretty tired of constantly having to trick the thermostat into hitting the right floor/ceiling number in a city that's hot one day and cold the next. If you ever get one you'll know what I mean.
