The Nest Learning Thermostat programs itself to help save energy. You can control it from anywhere with the Nest app. Works with the Nest Temperature Sensor to give you the right temperature, right where you want it ( sold separately ).


  • 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
