The Google Nest Learning Thermostat (3rd Generation) in Stainless Steel is a smart, programmable thermostat that learns your schedule and preferences and programs itself to help you stay comfortable while saving energy. It works with 95% of 24V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar, and geothermal systems.

The thermostat features a vibrant 2.08-inch diameter 24-bit color LCD display with 480x480 resolution at 229 pixels per inch. It includes temperature, humidity, proximity, motion, and ambient light sensors. Control your home temperature from anywhere using the Nest app on your phone or tablet, and receive alerts when temperatures drop to help prevent frozen pipes.

Key features include Auto-Schedule which learns temperatures you like and creates a schedule, Home/Away Assist that adjusts when you leave, and Farsight that lights up when it sees you coming to show you the time, temperature, or weather. The Nest Leaf icon appears when you choose an energy-saving temperature. The thermostat measures 3.3 inches in diameter and 1.21 inches in height when assembled, weighing approximately 8.6 oz. It connects via 802.11 a/b/g/n Wi-Fi and Bluetooth Low Energy. The built-in rechargeable lithium-ion battery is designed to work without a C wire in most homes.
