A thinner, sleeker design. A bigger, sharper display. The 3rd generation Nest Learning Thermostat is more beautiful than ever. With Farsight, it lights up when it sees you coming and shows you the time or temperature from across the room. And the Nest Thermostat is proven to save 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?
