Energy savings made brilliant.

The smartest, most advanced Nest thermostat yet. Smart Schedule learns the temperatures you like and when you like them, suggesting small tweaks to help you save directly in the Google Home app. The next-gen Nest Temperature Sensor comes in the box. Put it in any room to help manage hot and cold spots with ease. Natural heating and cooling helps to save energy by learning how the outside temperature heats or cools your home – like when it warms up on sunny days. Adaptive Eco finds an energy-efficient temperature that's just right for your home. It saves energy when you leave and it's comfy when you come back.

The big, borderless display with Dynamic Farsight shows you useful info that you can see from across the room. You can choose the design – a clock, the temperature, weather and more. System Health Monitor helps make sure that your heating and cooling system is running smoothly. It helps catch many issues early. And it can send an alert if something needs attention. Smart ventilation brings in fresh air from outside when air quality is healthy and the temperature is mildest, helping your home save energy. With Power Sharing, no C wire is required to install the Nest Learning Thermostat in most homes.

The Nest Learning Thermostat (4th gen) ships with one Nest Temperature Sensor (2nd gen) in the box. Finishes are Polished Silver and Polished Obsidian. The thermostat measures 98 mm in diameter and 29 mm deep and weighs 161.8 g, with a 2.7 inch (68 mm) circular liquid crystal display running at 600 x 600 pixels. A Soli sensor drives Motion Sense, alongside temperature, humidity and ambient light sensors. It connects over Wi-Fi 802.11n on both 2.4 GHz and 5 GHz, is Matter certified, and is controlled through the Google Home app or another Matter enabled app or voice assistant. Power comes from the HVAC system wiring with a built-in rechargeable lithium battery, drawing less than 1 kWh per month. It works with most 24 V systems including gas, electric, oil, forced air, heat pump and radiant, and controls heating stages W1, W2 and W3, cooling stages Y1 and Y2, heat pump with auxiliary and emergency heat, fan, humidifier, dehumidifier and ventilation. Patented Power Sharing means a C wire is not required in most homes. The bundle is made with at least 48% recycled materials, the battery contains 100% recycled cobalt, and the packaging uses 100% plastic-free materials. ENERGY STAR certified, with a 2 year standard retail warranty. Ships factory sealed from Toronto, Canada.
