Lately, we've seen the Ecobee3 smart thermostat go on sale a few times, and now it seems obvious why. Ecobee has announced its new smart thermostat, fittingly named the ecobee4. This time around, the thermostat has Alexa built-in, so you can talk to it to change the temperature (or do anything else Alexa can do).

If you're not familiar with the ecobee product line, its main selling point is the room sensors (the white square in the above image). They monitor a room to help manage hot and cold spots in your home, and should help save a bit on your power bills. Unfortunately, only one room sensor is included.

Just like the last model, the ecobee4 is also compatible with "most residential heating and cooling systems." It can also still be controlled by an external Alexa device, whether that be an Amazon Echo or your Alexa-equipped refrigerator.

You can already pre-order it from various retailers, including Amazon, Best Buy, Lowes, and Home Depot. It costs $249.99 for the ecobee4 and one room sensor.
