Learn how Google Nest products work together

Nest no longer supports Nest Secure. It will not be accessible in the Nest app and will no longer connect to the internet. You cannot use the Nest app to check the status of your Nest Secure, control your Nest Secure devices, or receive notifications from your alarm system.

Google Nest products are designed to work together. They can talk to one another and respond to things happening around your home. If one of your Nest products notices something important, your other products can help each other do the right thing. For example, if a Google Nest Protect detects smoke, a Google Nest thermostat can display an alert with the right settings.

In order to get alerts, manage your products, and use your phone’s location for certain features, you’ll need to install the Nest app or the Google Home app.

Keep in mind that the features listed below require an active Wi-Fi internet connection at the time of the event (like high smoke levels) and rely on having your Nest products in the same home on the same account in the Nest app or the same home in the Google Home app. If you have another home in your account, or more than one account, the Nest products in one won’t affect the behavior of products in the other.

When Protect detects smoke or carbon monoxide (CO)

With Wireless Interconnect, when one Nest Protect detects emergency levels of smoke or CO, all the other Protects in your home can sound the same alarm.

In addition, Protect can tell other products in your home about emergency alerts and have those products respond in helpful ways.

Disclaimer: In Australia, the light ring may only illuminate on the Protect that detects smoke or carbon monoxide, but interconnected Protects will still sound an alarm.

What other Nest products can do when Nest Protect detects smoke or CO


Smoke emergency

CO emergency

Google Nest thermostats

Google Nest cameras that you set up in the Nest app

  • Automatically turn on and start streaming video in the Protect alert on your phone or tablet. Tap the video to switch over to your camera’s live feed.

  • Record an emergency clip, even if you don’t have a Google Nest Aware subscription.
    Note: Emergency clip recording is turned off by default. To turn it on, from the Nest app home screen, select Protect and then Settings and then Works with Protect.

Other Nest Protects

  • Sound the same emergency alarm and let you know where the smoke is detected.

  • Sound the same emergency alarm and let you know where the CO is detected.

When someone rings your Google Nest doorbell

  • Google Nest and Home speakers and displays can automatically sound your Nest doorbell's chime and announce visitors.

  • With a Nest display, you can watch your Nest doorbell’s live video stream on the display’s screen and talk to visitors.

  • If you're a Nest Aware subscriber, your Nest doorbell will announce the visitor's name if they're in the familiar face library.

Old and new products work together

You don't need to upgrade your older products to get them to work with a newer one because they'll work together seamlessly. For instance, while 1st gen Protect smoke alarms don't have all the features of 2nd gen Protects, they will all speak to notify you when smoke or carbon monoxide is detected and sound the alarm if needed. The same goes for Nest thermostats and cameras. You can have 1st, 2nd and 3rd gen Nest Learning Thermostats control your multi-zone system together in the same home.

Older products that you set up with the Nest app will work seamlessly with newer ones that you set up with the Home app. We’ll also continue to add support in the Home app for older products.

Presence sensing helps products work together

When you enable presence sensing in the Home app (or Home/Away Assist in the Nest app), your phone and the sensors in your products can help tell when you've left or come back home. This can make each one better at doing the right thing at the right time. 

For example, if you have a thermostat, its occupancy sensors can help your system determine whether someone’s there or not. That way, all your other Nest products can automatically do the right thing based on where people are.
