Helps save energy. And keeps you comfortable.

The Nest Thermostat E’s energy-saving features have saved people an average of 10% to 12% on heating bills and 15% on cooling bills. Based on typical energy costs, that’s an estimated average savings of $131 to $145 a year.

  • Start with a simple schedule -s Up in the morning, down at night. Adjust it whenever you like from the Nest app.
  • Choose which rooms matter most - With the Nest Temperature Sensor, the baby’s room or the living room can get top priority. (Sold separately.)
  • Turns itself down when you leave - It uses your phone’s location to know you’re away.

Meet the Nest Temperature Sensor.

Most homes aren’t the same temperature in every room. With the Nest Temperature Sensor, you can let your Nest thermostat know which room should be a certain temperature at a certain time of day. Just put it on a wall or shelf in a room that matters most, like the living room or baby’s room. And get the right temperature, right where you want it. (Sold separately.)

A Nest home.

Nest products are made to work together. And they can even work with lights, locks and other products in your home.

If Nest Protect detects smoke, it can tell your Nest Thermostat E to turn off the heat to help keep the danger from spreading throughout your home. See how it works >

It’s easy to install.

Most people install their Nest Thermostat in 60 minutes or less. Need help? Find a Nest Pro to do it for you.

The Nest Thermostat E is compatible with most heating and cooling systems.


The Nest Thermostat E works with 85% of 24V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar and geothermal.

The Nest Thermostat E is designed to work even if your home doesn’t have a common (C) wire, but installing a new C wire may be required.

If you have a dual fuel system, we strongly recommend professional installation.

The Nest Thermostat works in most homes. It figures out what system you have and turns on the right features for you.
