Set up Nest Protect with the app

Important: You need to set up Protect with the Nest app before installing it on the ceiling or wall.

Setup only takes a few minutes, and the Nest app will guide you through it.

Once connected to the app and Wi-Fi, you can silence Protect with the app, get alerts on your phone, and more. If you don’t add your Protect to the Nest app, it will still warn you when it detects smoke and carbon monoxide (CO), but you won’t get notifications from the app.

We've provided detailed setup steps below, but if your prefer, check out the Protect setup video.

How to set up Nest Protect with the Nest app

  • Latest version of the Nest app
  • Be logged into your Nest or Google Account in the app
  • Requirements to use the Nest app

1. Put your Protect near your Wi-Fi router

If you’re installing more than one Protect

2. Turn on your phone's Wi-Fi and Bluetooth 
  1. Make sure your phone is connected to the same Wi-Fi network that you're connecting Protect to. The Nest app will automatically turn Wi-Fi and Bluetooth on. 
    Important: Sometimes Android devices won’t immediately connect to Protect over Wi-Fi and will automatically switch to cellular data.
  2. ​​​​Disable cellular data before you set up your Protect. Once you’re done with setup, you can turn it back on. 
    1. Go to Settings Data Usage   Mobile Data and tap or uncheck to turn off mobile data. If your device is running a custom version of the Android OS, your menus may be different. 
       Note: If you have a 1st gen Protect, bluetooth doesn’t need to be on since it doesn’t use Bluetooth Low Energy (BLE)
  3. Check Wi-Fi settings. Some Android devices have automatic network switching options, which should also be disabled.
    1. This option is often in Settings   Wi-Fi   Advanced.
      • If your device runs a custom version of the Android OS, your menus may be different.
    2. Uncheck Avoid poor connections. You can turn it on again after setup is complete. 

     You may need to turn off and restart your Android device for these changes to take effect. After restart, double       check that Wi-Fi is back on.

3. Get the Nest app 

  • If you don’t already have the Nest app, go to the Google Play store to download it.
  • If you already have the Nest app, check that you have the latest version.
    • On an Android device, open the Google Play app and search for the Nest app. Update the app if necessary.

4. Create a free account 

  • If you already have an account in the Nest app, go to step 5.
  • If you’re new to Nest, you’ll be asked to create a free account. Tap Sign up in the app.

6. Scan the QR code

Troubleshoot QR code scanning

The app will automatically recognize that you’re adding a Protect and guide you through setup. Make sure you have your Wi-Fi password handy.

Tip: Write down the Entry Key for each Protect you install and keep this number in a safe place. The entry key is 6 digits long, located on the back next to the QR code. This can save you some time in the future if you ever remove your Protect from the app and need to add it back.

7. Tell your Protect where you're going to install it

Pick a location from the list of rooms in the app. Protect will speak the room name you’ve chosen during a Heads-Up alert or Emergency Alarm. You can also add a label or create a custom name.

You can always change this information later if you need to.

8. Pull out Protect's battery tab 

Pull out the blue tab on your Protect. It will greet you and the light will begin to glow blue.

If you’ve already pulled the tab out, but the light isn’t
blue, press the button on your Protect to wake it up.

Note: If you have a Protect already connected to the app,
you may be able to skip some of the following steps. The app
will tell you exactly what you need to do.

If a blue light doesn't appear or you don't get a welcome message after removing the battery tab, the batteries may need to be pushed back into place or part of the battery tab may have broken off. To fix the problem, use the steps in this help center article to remove the batteries then check for pieces of the battery tab that are left in the battery tray and put the batteries back in.

For 1st gen Protects: Connect to Protect's Wi-Fi network 

Your Protect uses a temporary Wi-Fi network to complete setup. This lets you connect your phone to your Protect so you can tell it your home’s Wi-Fi network name and password.

If you have an Android device, the Nest app will automatically connect you to the temporary Wi-Fi network. Your phone or tablet will now connect to Protect. It may take a minute or 2.

After joining the temporary network, there won't be a Wi-Fi icon in the top left of the screen. You will only get a 4G or 3G icon when pairing is fully completed.

Note: If your Protects have connected to each other, you may be able to skip some of the following steps.

9. Connect Protect to Wi-Fi 

If you already have a Protect connected to the Nest app

The app will ask you to press its button so it can connect to your new Protect. This will let them share Wi-Fi information and automatically connect.

If your Protect’s light isn’t spinning blue already, press the button to wake it up. Then it will connect to your new Protect and transfer your Wi-Fi network information. It may take a minute or two.

Important: Your Protects need to be in range of each other. You may need to take your phone and new Protect to the same room as your other Protect.

If you don’t already have a Nest Protect connected to the Nest app

The app will show you a list of available Wi-Fi networks. Select the network you want your Protect to connect to and enter the password. Your phone or tablet will now connect to Protect. It may take a minute or 2.

If you get a notification in the app that the batteries are low or if your Protect starts to chirp during setup, your battery voltage may have temporarily dropped. If this happens, follow these troubleshooting steps.

If you run into trouble or get an error, go to the following articles:

10. Choose Pathlight settings 

Choose Pathlight settings so Protect can light your way in the dark. You can choose to have it off, on, or always on.

11. Finish setup 

Protect will connect to the internet and appear in the Nest app, and its light will turn green.

12. Label your Protect 

Write down the date and room name you chose on the back of each Protect. This helps you keep track of where they’re supposed to be installed.

Note: You can also press the button on your Protect to hear where it’s supposed to go.

13. Add another Protect if you have one 

The Nest app will ask if you have more Protects. If you do, it can take you through a faster setup for the rest of them. Tap Add another Nest Protect and the app will walk you through the setup process for your other Protect.

If you’re done setting up your Protects, tap Next.

14. Choose Sound Check settings 

After you’re finished adding all your Protects to the Nest app, you’ll choose Sound Check settings. This lets your Protects automatically test their speaker and alarm once a month.

15. Keep it clean until you install 

Like all smoke alarms, it’s important to keep Protect dust free. Use the plastic cover or the box that it came in to keep dust out until you’re ready to install it.
