It’s winter -- despite the lack of snow across most of the U.S. -- and temperatures may not be freezing but they're definitely cold. The solution? Hibernate inside in comfort with these new app / hardware combos for your house. They may even help you save on your energy bill.

Nest

Save energy using Nest, the learning thermostat. First install the device in your home, then download the app to control it. Adjust the thermostat as you would your old one and within a week it will learn what keeps you comfortable and auto adjust.

Having the Nest app installed on your smartphone also gives you the ability to adjust the temp anytime from anywhere. If you're going to be home later than usual, simply tap to turn the heat down. The app is free; the hardware costs $249.
