Before you begin, it’s important to know which Nest Doorbell you’re working with. Google has released several models over the years, and the setup process can vary slightly depending on the version.
Nest Doorbell (Wired) – 1st Gen
This model requires a wired connection to your home’s doorbell transformer and chime. It uses the Nest app for setup and management.
Nest Doorbell (Battery) – 2nd Gen
Released in 2021, this version can run on battery or be hardwired. It’s designed to work with the Google Home app, though some features may still use the Nest app.
Nest Doorbell (Wired, 2nd Gen)
Launched alongside the battery model, this wired version also uses the Google Home app and offers improved video quality and smarter alerts.
How to Identify Your Model
Check the back of the doorbell or the original packaging. You can also look up the model number in the app or on the Google Store website. Knowing your model helps ensure you follow the correct setup steps.
Preparing for Setup
Before connecting your Nest Doorbell, take a few minutes to prepare. This will save you time and prevent common setup errors.
Gather Your Tools
You’ll need:
- A smartphone or tablet with the Google Home or Nest app installed
- A stable 2.4 GHz Wi-Fi network (5 GHz is not supported)
- A ladder (if mounting or adjusting the doorbell)
- A screwdriver (for wired installations)
- The doorbell’s mounting plate and screws (if replacing an old doorbell)
Check Your Wi-Fi Signal
Nest Doorbells rely heavily on Wi-Fi. Use a Wi-Fi analyzer app to check signal strength at your front door. If the signal is weak, consider using a Wi-Fi extender or mesh network to boost coverage.
Ensure Proper Power Supply
For wired models, your doorbell needs a transformer that provides 8–24 volts AC. Most older doorbells use 16V, which is ideal. If you’re unsure, consult an electrician. Battery-powered models should be fully charged before setup.
Download the Correct App
- For Nest Doorbell (1st Gen): Use the Nest app (available on iOS and Android).
- For Nest Doorbell (Battery or Wired, 2nd Gen): Use the Google Home app.
Make sure the app is updated to the latest version.
Resetting the Existing Nest Doorbell
If your doorbell was previously installed and connected to another account, you’ll need to reset it before you can connect it to yours. This ensures the device is clean and ready for a new setup.
Why Reset?
Resetting removes all previous settings, Wi-Fi credentials, and user accounts. It’s like giving the doorbell a fresh start.
How to Reset a Nest Doorbell
The reset process varies slightly by model:
For Nest Doorbell (1st Gen – Wired)
- Remove the doorbell from the mounting plate.
- Locate the reset button on the back (small pinhole).
- Use a paperclip or SIM tool to press and hold the button for 10 seconds.
- The status light will blink yellow, then turn solid yellow. Release the button.
- Wait for the light to turn off and back on—this means the reset is complete.
For Nest Doorbell (Battery or Wired, 2nd Gen)
- Remove the doorbell from the mount (slide up and pull forward).
- Press and hold the button on the back (below the camera) for 20 seconds.
- The status light will blink white, then turn solid white. Release the button.
- The doorbell will restart and enter setup mode (light will pulse blue).
What If the Reset Doesn’t Work?
If the light doesn’t respond or the doorbell won’t reset:
- Ensure the battery is charged (for battery models).
- Check that the doorbell is receiving power (for wired models).
- Try the reset process again, holding the button longer.
- Contact Google Support if the issue persists.
Connecting to Wi-Fi
Once the doorbell is reset, it’s time to connect it to your home Wi-Fi network. This step is crucial for live streaming, alerts, and remote access.
Open the App
Launch the Google Home or Nest app on your phone. Make sure you’re signed in to your Google account.
Start the Setup Process
In the Google Home App (2nd Gen Models)
- Tap the “+” icon in the top-left corner.
- Select “Set up device.”
- Choose “New device” and follow the prompts.
- When asked to scan a code, point your phone at the QR code on the doorbell’s back or packaging.

In the Nest App (1st Gen Models)
- Tap the “+” icon and select “Add product.”
- Choose “Doorbell” and follow the on-screen instructions.

Select Your Wi-Fi Network
The app will search for available networks. Select your 2.4 GHz Wi-Fi network (not 5 GHz). Enter the password when prompted.
Wait for Connection
The doorbell will attempt to connect. This can take 1–3 minutes. You’ll see a progress bar in the app.
Troubleshooting Wi-Fi Issues
If the connection fails:
- Move closer to your router during setup.
- Restart your router and try again.
- Ensure your Wi-Fi password is correct.
- Check for interference from other devices (microwaves, cordless phones).
- Use a Wi-Fi extender if the signal is weak at the door.
Mounting and Positioning the Doorbell
Proper placement ensures the best video quality and motion detection.
Choose the Right Spot
- Mount the doorbell at a height of 48–60 inches (eye level).
- Angle it slightly downward to capture visitors’ faces.
- Avoid direct sunlight or bright lights that can cause glare.
- Ensure it’s within range of your Wi-Fi signal.
Install the Mounting Plate

- Drill pilot holes if needed.
- Secure the plate with screws.
- For wired models, connect the wires to the terminals (polarity doesn’t matter).
Attach the Doorbell
Slide the doorbell onto the plate until it clicks. For battery models, make sure the battery is inserted.
Completing the Setup in the App
Once connected, finish configuring your doorbell in the app.
Name Your Doorbell
Give it a name like “Front Door” or “Side Entrance” so you can easily identify it.
Set Up Motion and Ring Alerts
Choose when you want to receive notifications:
- All motion

You can also adjust sensitivity to reduce false alerts.
Enable Two-Way Audio
Test the microphone and speaker by tapping the talk button in the app. Speak and listen for clear audio.

Tips for Safe Sharing

Keeping Your Doorbell Updated
Google regularly releases firmware updates to improve performance, security, and features.
Check for Updates
The app usually installs updates automatically. To check manually:
- In the Google Home app: Tap the doorbell > Settings > Technical Info > Firmware.

Ensure Automatic Updates
Make sure “Auto-update” is enabled in the app settings. This keeps your doorbell secure and up to date.
