As far as its connected features go, the SmartThermostat has exactly the same capabilities as the Ecobee4 and Ecobee3 before that. (In fact, if you are upgrading from an Ecobee3 or Ecobee4 to the SmartThermostat, you can program your existing room sensors to work with the new thermostat.) It has all of the stuff you want in a smart thermostat: intelligent scheduling, smartphone app control, and presence detection so it can automatically tell when you’re home or not and adjust your HVAC system accordingly. Ecobee’s key differentiator is the included remote sensor, which allows you to measure the temperature in different parts of your home and balance the system accordingly, without the need for multiple zones.
