No imbalance of temperatures will be felt in different rooms of the house if you have the Ecobee3. The purpose of this wi-fi thermostat is to give you the right temperature in the rooms that matter the most to you. So if you’ve had a toasty kitchen and a chilled bedroom till now, it’s time you could do with some balance. It comes with one free remote sensor which can measure the temperature and occupancy of a room and deliver accordingly. You can add up to 32 sensors. The more you add, the smarter your Ecobee3 becomes. Every time you leave a room or whenever the occupancy decreases, the sensor will save energy for you. It’s not just a thermostat; it’s one of the best you can have at home.
