Question: is ecobee or nest better?
Answer: Ecobee is more efficient than Nest at knowing if you're home or away because it has a motion sensor on the base and uses additional SmartSensors to detect motion and temperature. One room sensor is included with Ecobee SmartThermostat (none with Ecobee3 Lite), and you can add up to 32 SmartSensors to any Ecobee system.
