Programs itself. Saves energy. Nest is the first thermostat that learns from you. Stay comfortable when you’re home, save energy when you’re away. Builds a schedule Nest programs itself in about a week. It creates a personalized schedule based on the temperature changes you’ve made. This flexible schedule adapts to your changing life. The Leaf The Nest Leaf appears when you set a temperature that saves you energy-and money. The Leaf guides you in the right direction and helps you be energy-efficient. Auto-Away About two hours after you’ve left the house, Nest will sense you’ve gone and adjust the temperature to avoid heating or cooling an empty home. Energy History Nest shows you how much energy you’ve used and if your temperature adjustments, Auto-Away or the weather affected your energy use most.
