Grow Your Nest Family

Now that your Nest Thermostat is up and running, consider expanding your Nest home. Nest products are made to work together. In fact, each of the Nest products below talks to your Nest Thermostat to give you greater control and more peace of mind.

Nest Protect™ smoke + carbon monoxide alarm

Your heating system could be a source of carbon monoxide leaks or it could spread smoke through your home in a fire. If there’s a carbon monoxide leak, Nest Protect can tell your Nest Thermostat to turn off the heat. If Nest Protect detects smoke, your Nest Thermostat can turn off the fan.
