Growing up, my parents always had pretty clear rules around the thermostat: you touch it, you get grounded. In fact, they were so strict about it that even now as an adult, I get nervous going near one and prefer to be as hands-off as possible. You might say that's part of the appeal of getting a smart thermostat in the first place, since they allow you to regulate your home's temperature quickly and easily from afar.

Smart thermostats, which usually come with a touch screen and mobile apps, are designed to make the experience of setting temperatures around the house more intuitive. Right now, you can get the best value smart thermostat we've ever used—the Emerson Sensi Wi-Fi smart thermostat—at its lowest price as part of a bundle with a brand new Echo Dot (3rd Gen.) on Amazon.

Even better, the bundle is less expensive than getting Sensi smart thermostat on its own, since ordinarily a Sensi Wi-Fi smart thermostat alone goes for around $100, while an Echo Dot (3rd Gen.) usually retails for about $50 (although it is on sale for $24.99). That means you're saving about $75 with this bundle.

In testing, our reviewers loved this no-frills thermostat, raving that it had nearly the same functionality as the Sensi Touch thermostat, which is the best smart thermostat we've tested, but comes with a significantly more expensive price tag. Although it doesn't have a touch screen like the Sensi Touch, they were virtually identical in their compatibility with Alexa, Google Home, and Apple Homekit/Siri and our reviewers said this was fairly straightforward to set up.

This deal only lasts until Wednesday, December 18, which means you have limited time to take advantage of this deal, and possibly save even more on your heat bill, so take advantage of it now while you can.
