While the Nest would beat it in a beauty contest, this Sensi thermostat has most of the same smart features in a more traditional body, and it’s a hell of a lot cheaper.

One of the most notable of those smart features is Alexa support; if there’s an Amazon Echo in range, you can change your home’s temperature with nothing but your voice. For a limited time, you can get the Sensi and an Echo Dot for just $108, which is $71 less than buying them separately, and somewhat incredibly, $21 less than buying the thermostat by itself.
