The 3rd­generation Nest Learning Thermostat in stainless steel is slimmer, sleeker and even more beautiful. With a bigger, sharper display and Farsight, you can see the time or the temperature you’ve set from across the room. And now it even controls your hot water tank.

The Nest Thermostat learns the temperature you like, then programs itself. It knows how long it takes to heat your home so that you’re comfortable when you get there. When you leave, it turns itself down so that you save energy. And you can check your Energy History with the Nest App to see how much you’ve saved.
