Google Nest 3rd Generation Learning Thermostat (Mirror Black) T3018US

This Nest Learning Thermostat memorizes your favorite temperature settings and adjusts throughout the day. You can also control this Wi-Fi thermostat from your smart phone or other remote devices while you’re away. Redesigned with a sleeker, thinner look for a larger, sharper display, the Nest thermostat lights up and easily displays the temperature when you enter a room. This ENERGY STAR-rated thermostat saves you on your energy bills: up to 12 percent on heating bills and 15 on cooling, paying for itself in fewer than two years.

Programs itself. Then pays for itself.
Meet the 3rd gen Nest Learning Thermostat. It has new rings and a big, sharp display. And it saves energy. That's the most beautiful part.

Your thermostat controls half your energy bill - more than appliances, more than electronics. So shouldn't it help you save energy?

The Nest Learning Thermostat is the first thermostat to get ENERGY STAR certified. It learns what temperature you like and builds a schedule around yours. Since 2011, the Nest Thermostat has saved billions of kWh of energy in millions of homes worldwide. And independent studies showed that it saved people an average of 10% to 12% on heating bills and 15% on cooling bills. So in under two years, it can pay for itself.

See how much you saved.
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.

Follow the Leaf.
Change the temperature to save energy and you'll be rewarded with a Leaf. The Leaf learns how to help you save, so it appears at different temperatures for different families.

Meet the Nest Temperature Sensor.
Most homes aren't the same temperature in every room. With the Nest Temperature Sensor, you can let your Nest thermostat know which room should be a certain temperature at a certain time of day. Just put it on a wall or shelf in a room that matters most, like the living room or baby's room. And get the right temperature, right where you want it. (Sold separately.)

It lights up when you walk in the room.
Now the Nest Thermostat does something new. It's called Farsight, and it lights up to show you the temperature, weather or time. You can even choose a digital or analog clock face. Farsight is big and bright on the beautiful display - you can see it from across the room.

Know your home is safe.
The Nest Thermostat is just one part of your heating and cooling system. But it can keep an eye on the rest of it. 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.
