Smart Home

Use your Amazon Echo to crank the AC before you get home

Alexa works with smart thermostats like Nest and Ecobee to control the temperature remotely.

Tyler Lizenby/CNET

Smart thermostats like Nest and Ecobee were made for remote control so you can set the temperature of your home from afar. Amazon Echo ($80 at Amazon) voice control with Alexa takes these devices a step further by letting you control your thermostat remotely with just your voice.

For example, if you have a lake house that's two hours away (because, who doesn't?), or you're feeling comfy on the couch or busy in the kitchen, you can say "Alexa, ask [Ecobee or Nest] to set the temperature to 70 degrees," without ever touching your thermostat.

Before you get started, make sure your Amazon Echo and Nest or Ecobee are linked to the same Amazon account, otherwise they won't sync.
