With the ship date of the Ecobee4 smart thermostat ten days away, the deals have been increasing on the current Ecobee3 model. Right now, Amazon is selling the second-generation Ecobee3 for $187. That’s $63 off the sticker price, as well as being about $13 cheaper than at other retailers.
The Ecobee3 can monitor multiple rooms in a home—though it comes with one wireless sensor, it can support up to 32. Its premise is that it dynamically adjusts the temperature based on which rooms are occupied and what their conditions are. (As long as you have a sensor to relay to the main unit such information, of course.) The company claims an average of 23% savings on your heating and cooling costs per year.
