Product Details :
Slash your energy bills with the Google Nest Learning Thermostat (3rd generation), the slimmest and smartest version yet. It learns the temperatures you like and creates a custom schedule for your home. Nest uses built-in sensors to automatically adjust itself after you leave so you’re not heating or cooling an empty home with the Auto-Away Function. Once you connect your thermostat to Wi-Fi, you can control your heating and water from anywhere using the Nest App on your phone, tablet or laptop. The Energy History feature shows you how much energy you use every day, and every month in your Home Report. You can see when you use more energy, such as at the weekend or Monday nights, and how to use less. With the new Farsight feature, Nest’s Thermostat lights up when you’re near and shows the time, weather or temperature you’ve set.
