Those of you who got in on the Ecobee Smart Thermostat deal that I posted about earlier, or if you already own an Ecobee Thermostat, you might be interested in this deal on additional remote sensors. Best Buy currently has the Ecobee Remote Sensor 2-Pack on sale for $39.50. That is half off of the regular price of $79 for this bundle. These sensors allow you to monitor the temperature in rooms where the Ecobee thermostat is not located so that you can have the thermostat tailer the temperature for a specific room. The Ecobee 4, which is on sale now for $199, already comes with one room sensor, but the Ecobee 3, which is on sale for $139, does not come with any, even though it is compatible with the same sensors.
