Google Nest Learning Thermostat (3rd Gen)

The Nest Learning Thermostat automatically creates a personalized schedule based on your habits. After about a week, it knows when you're home, when you're asleep, and when you're away — adjusting temperature automatically to save energy without sacrificing comfort.

Home/Away Assist uses phone location and built-in sensors to detect when everyone has left and enters Eco mode automatically. Energy History in the Nest app shows exactly how much energy you're using and why, helping you make smarter climate decisions.

Control from anywhere via the Nest app: adjust temperature remotely, check energy usage, or receive alerts if your home gets too hot or cold. Works with Alexa, Google Assistant, and IFTTT for voice control and automation.

The thermostat's Farsight feature lights up when you enter the room, displaying time, weather, or temperature on the high-resolution display. Studies show Nest saves an average of 10-12% on heating and 15% on cooling bills.
