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.


Auto-Schedule - No more confusing programming. Nest learns the temperatures you like and programs itself

Nest Leaf - The Nest Leaf appears when you turn Nest to a temperature that's energy efficient. It guides you in the right direction

Auto-Tune - Auto-Tune finds ways to automatically lower your energy bill while keeping you comfortable. It enables two Nest features: Rush Hour Rewards and Seasonal Savings

System Match - Get the most out of your high–efficiency system. Nest turns on specific features for forced air, heat pump or radiant to help you save energy and stay comfortable

Sunblock - In many homes the thermostat is in direct sunlight, causing it to warm up. Nest automatically adapts to direct sunlight to read and set the right temperature

Nest will optimize itself for you and your system
