Before you touch a single wire, gather all the tools and materials you’ll need. This will save time and prevent frustration during installation.
Tools and Materials
- Nest Doorbell (wired version)
- Screwdriver (Phillips and flathead)
- Voltage tester (non-contact type recommended)
- Drill and drill bits (if mounting on brick, concrete, or hard surfaces)
- Wall anchors (if needed)
- Smartphone or tablet with the Google Home or Nest app installed
- Stable Wi-Fi network (2.4 GHz recommended)
- Optional: Wire strippers, electrical tape, level
Check Compatibility
Not all homes are ready for a smart doorbell. The Nest Doorbell (wired) requires:
- A working doorbell transformer that outputs 16–24 volts AC
- Existing doorbell wiring (two wires: front and transformer)
- A chime inside the house (mechanical or digital)
If you’re unsure about your transformer, use a multimeter or voltage tester to check the voltage at the doorbell terminals. If it’s below 16V, the doorbell may not work properly. In that case, you may need to upgrade your transformer or consider the battery-powered Nest Doorbell (which doesn’t require wiring).
Step 1: Turn Off the Power
Safety first! Working with electrical wiring can be dangerous if the power is on.
Locate Your Circuit Breaker
Go to your home’s electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “doorbell,” “chime,” or “front door.” If there’s no label, you may need to test breakers one by one.
Turn Off the Breaker
Switch the breaker to the “off” position. To be extra safe, use a non-contact voltage tester at the doorbell location to confirm no electricity is flowing.
Pro Tip: Take a photo of your breaker panel before turning anything off. This makes it easier to turn the right breaker back on later.
Step 2: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it first.
Unscrew the Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the faceplate away from the wall.
Disconnect the Wires
You should see two wires connected to the back of the doorbell. Loosen the terminal screws and carefully pull the wires free. Don’t let them fall back into the wall!
Important: Label the wires if possible (e.g., “Front” and “Trans”) or take a photo so you remember which goes where.
Tuck Wires Safely
Use electrical tape to wrap the exposed ends of the wires to prevent short circuits. Push them gently back into the wall cavity.
Step 3: Prepare the Nest Doorbell Mounting Plate
The Nest Doorbell comes with a mounting plate that secures the device to your wall.
Choose the Right Mounting Option
Depending on your wall type and doorbell angle, you may need:
- Standard mount: For flat, even surfaces.
- Wedge mount: For angled walls (up to 10 degrees).
- Trim plate: For covering gaps or uneven surfaces.
If your door is set back or your wall is uneven, use the wedge or trim plate for a better view and secure fit.
Attach the Mounting Plate
Hold the mounting plate (with wedge or trim, if using) against the wall where you want the doorbell. Use a level to make sure it’s straight.
Mark the screw holes with a pencil. If you’re drilling into brick, concrete, or tile, use a masonry bit and wall anchors.
Drill pilot holes, then secure the plate with the provided screws.
Step 4: Connect the Wires to the Nest Doorbell
Now it’s time to connect your home’s wiring to the Nest Doorbell.
Strip the Wire Ends (If Needed)
If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper. Be careful not to cut too much.
Insert Wires into the Nest Doorbell
The Nest Doorbell has two wire terminals labeled “Front” and “Trans.” It doesn’t matter which wire goes where—Nest uses polarity-free technology.
Push each wire into the corresponding terminal and tighten the screw to secure it. Make sure the connection is snug but don’t overtighten.
Pro Tip: If your wires are too short, you can use wire extenders or pigtail connectors (available at hardware stores).
Step 5: Attach the Nest Doorbell to the Mounting Plate
With the wires connected, it’s time to mount the doorbell.
Align and Secure
Slide the Nest Doorbell onto the mounting plate. You’ll hear a click when it’s properly seated.
Use the included security screw and screwdriver to lock the doorbell in place. This prevents theft or tampering.
Check the Angle
Make sure the camera has a clear view of your doorstep and walkway. Adjust the wedge or trim plate if needed.
Step 6: Turn the Power Back On
Now that everything is connected, restore power.
Flip the Breaker
Go back to your electrical panel and turn the breaker back on.
Wait for the Doorbell to Power Up
The Nest Doorbell will light up and begin initializing. This may take 30–60 seconds.
You should hear a chime from your indoor doorbell if it’s working properly.
Step 7: Set Up the Nest Doorbell Using the App
The final step is connecting your doorbell to your smartphone and Wi-Fi network.
Download the App
If you haven’t already, download the Google Home app (recommended) or the Nest app from the App Store or Google Play.
Create or Sign In to Your Account
Open the app and sign in with your Google account. If you don’t have one, create it—it’s free and required for Nest devices.
Add Your Doorbell
Tap the “+” icon in the app and select “Set up device.” Choose “Doorbell” and follow the on-screen instructions.
The app will guide you through:
- Scanning the QR code on the back of the doorbell
- Connecting to your Wi-Fi network (2.4 GHz recommended)
- Setting up motion and sound alerts
- Choosing notification preferences
Test the Doorbell
Once setup is complete, test the doorbell by pressing the button. You should:
- Hear a chime inside your home
- Receive a notification on your phone
- See a live video feed in the app
If everything works, congratulations—you’ve successfully installed your Hello Nest Doorbell!
Troubleshooting Common Installation Issues
Even with careful installation, problems can happen. Here’s how to fix the most common issues.
Doorbell Doesn’t Power On
- Check the breaker: Make sure power is restored.
- Test voltage: Use a multimeter to confirm 16–24V at the terminals.
- Inspect wiring: Ensure wires are securely connected and not loose.
No Chime Inside the House
- Check chime compatibility: Some digital chimes may not work with Nest. Use the Nest Chime Connector if needed.
- Test old doorbell: Reconnect the old doorbell briefly to see if it chimes. If not, the issue may be with the chime unit or transformer.
Weak Wi-Fi Signal
- Move your router: If possible, place the router closer to the door.
- Use a Wi-Fi extender: A mesh network or extender can boost signal to the front door.
- Switch to 2.4 GHz: Nest Doorbell works best on 2.4 GHz networks, which have better range.
Blurry or Dark Video
- Clean the lens: Use a soft, dry cloth to wipe the camera.
- Adjust lighting: Avoid pointing the camera directly at bright lights or sunlight.
- Check night vision: Make sure the IR LEDs are unobstructed.
False Motion Alerts
- Adjust sensitivity: In the app, lower motion detection sensitivity.
- Set activity zones: Define specific areas (like the walkway) to monitor.
- Trim bushes or trees: Overgrown plants can trigger motion sensors.
Tips for Getting the Most Out of Your Nest Doorbell
Now that your doorbell is installed, here are some tips to enhance your experience.
Customize Alerts
In the app, you can choose to receive alerts for:
- Motion detection
- Person detection
- Package delivery
- Sound detection (like a dog barking)
Turn on “Familiar Faces” to get notified when family members arrive.
Use Two-Way Audio
Talk to visitors remotely using the app. Great for telling delivery drivers where to leave packages.
Enable Video History (Optional)
Subscribe to Nest Aware for cloud storage of video clips. You’ll get 24/7 recording, event history, and intelligent alerts.
Integrate with Other Smart Devices
Connect your Nest Doorbell to Google Assistant, smart lights, or security systems for a fully automated home.
For example, set lights to turn on when motion is detected at night.
