Google Nest Learning Thermostat

The Nest Learning Thermostat is the first smart thermostat to receive ENERGY STAR certification.
It’s sleek design and easy-to-use interface has helped save users an average of 10% to 12% on heating bills and 15% on cooling bills. So in under two years, it can pay for itself. Not only can it save you money, it saves you time. The Nest Learning Thermostat automatically adapts as your life and the seasons change after a week of use. Even installation is easy - it takes only 30 minutes.

The Nest Learning Thermostat has a beautiful, sleek design that informs you of your usage patterns and when you are saving energy.
Nest shows you how much energy you use every day in Energy History and every month in your Home Report. So you can see when you use more energy, like on weekends or Monday nights, and how to use less. Look for the Leaf when you change the temperature to save energy in your home: it learns how to help you save, so it appears at different temperatures for different families. When the Nest Thermostat notices you’re there, Farsight shows you the temperature, weather or time. Press the display and turn the ring. You’ll see a summary of what your thermostat is up to and you can reach Settings, Energy History, or your schedule.

With the Nest app, your thermostat lives on your wall and in your pocket.
Once you connect your thermostat to Wi-Fi, you can control it from anywhere. Adjust the temperature from the app, and the Nest Thermostat adjusts quickly back at home. You’ll get an alert on your phone if there’s something wrong — like temperatures are so low your pipes could burst. And if it looks like your furnace is acting up, the Nest Thermostat will send you an alert.
