Ecobee3: If you're crazy enough to want a smart thermostat – but not too crazy – this is for you

The elephant in the room...

If you live in an energy efficient dwelling, then that implies that it has a fair amount of insulation and hopefully some thermal mass inside the thermal envelope. The individual rooms (being so well insulated from the outside) don't drift very far apart. It also follows that the heating system can be of fairly low power (e.g. 10 kW or 34kBTU/h). The end result is that the thermal time constant is extended. E.g. It can take hours for the house to drop in temperature for the usual overnight temperature reduction. (Applies to aircon too, in the opposite direction.)

If your dwelling's temperature is going up and down like a yoyo, and you thus benefit from room occupancy sensors and endless adjustments, then your dwelling is hardly energy efficient.

In summary - you're doing it wrong.
