Before diving into installation, gather these tools and materials. Having everything ready saves time and frustration.
- Nest Hello doorbell kit: Includes the doorbell, mounting plate, screwdriver, wire labels, chime connector, and drill bit (if needed).
- Screwdriver (Phillips head): Most standard screwdrivers work, but the one in the kit is handy.
- Drill and drill bits (optional): Only if you need to make new mounting holes or run wires.
- Voltage tester (recommended): To confirm your doorbell transformer outputs 16–24V AC.
- Smartphone with the Nest app: Download it from the App Store or Google Play.
- Wi-Fi network: Your home network should support 2.4 GHz (5 GHz is not supported by Nest Hello).
- Ladder (if needed): For reaching high doorframes or entryways.
Pro tip: If your existing doorbell uses a mechanical chime (the classic “ding-dong” kind), you’ll likely need the chime connector included in the box. We’ll cover that later.
Step 1: Check Compatibility
Not every home is ready for the Nest Hello right out of the box. Before you remove your old doorbell, verify that your wiring and transformer can support it.
Check Your Doorbell Wiring
Most homes have low-voltage doorbell wiring running from a transformer (usually near your furnace or breaker panel) to the doorbell button and chime. The Nest Hello requires two wires: one for power and one for the chime signal.
If your current doorbell has two wires connected, you’re probably good to go. If it’s wireless or battery-powered, you’ll need to run new wires—which is more advanced and may require professional help.
Test Your Transformer Voltage
The Nest Hello needs 16–24 volts AC from your transformer. Too little voltage, and it won’t work. Too much, and you could damage the device.
Here’s how to check:
- Turn off power to your doorbell at the breaker.
- Remove your existing doorbell button.
- Use a voltage tester or multimeter to measure the voltage across the two wires.
- If it reads between 16 and 24 volts AC, you’re set. If it’s below 16V, you may need a higher-voltage transformer. If it’s above 24V, consult an electrician.
Don’t have a multimeter? You can often find the transformer’s voltage rating printed on its side. Look for labels like “16V” or “24V.”
Check Your Chime Type
The Nest Hello works with both mechanical and digital chimes, but mechanical chimes (the kind with physical bells or sliders) often need the chime connector to prevent issues like constant buzzing or failure to ring.
If your chime makes a traditional “ding-dong” sound, use the chime connector. If it’s a newer digital chime with multiple tones or lights, you might not need it—but it’s safer to install it anyway.
Step 2: Turn Off the Power
Safety first! Even though doorbell wires carry low voltage, they can still give you a shock or damage your new device if mishandled.
Locate Your Breaker Panel
Find your home’s main electrical panel. Look for a breaker labeled “doorbell,” “chime,” or something similar. If you can’t find it, turn off the main breaker to be safe.
Test That Power Is Off
After switching off the breaker, go back to your doorbell and press the button. If the chime doesn’t ring, power is off. For extra safety, use a non-contact voltage tester near the wires to confirm no current is flowing.
Never skip this step—even if you’re confident the power is off. It only takes a second and could save your device—or yourself.
Step 3: Remove Your Old Doorbell
Now it’s time to take down the old doorbell button.
Unscrew the Old Button
Use your screwdriver to remove the two screws holding the doorbell button to the wall. Gently pull the button away from the wall so you can access the wires.
Label the Wires
Before disconnecting anything, label the wires with the included stickers (usually “Front” and “Trans”). This helps you reconnect them correctly later. If your labels fall off, take a photo with your phone as a backup.
Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. Don’t let them fall back into the wall—use tape to hold them in place if needed.
Set the old doorbell aside. You won’t need it anymore.
Step 4: Install the Chime Connector (If Needed)
If you have a mechanical chime, installing the chime connector is crucial. It regulates the power flow so your chime rings properly and prevents damage to the Nest Hello.
Access Your Chime Box
The chime is usually located near your front door, inside the house. Open the chime cover to reveal the wiring.
Identify the Wires
You’ll see two sets of wires: one from the transformer and one from the doorbell button. The chime connector goes between these.
Connect the Chime Connector
Follow the instructions in the Nest Hello box:
- Disconnect the wire from the “Front” terminal on the chime.
- Connect that wire to one side of the chime connector.
- Connect a new wire (included) from the other side of the connector back to the “Front” terminal.
- Connect the second wire from the connector to the “Trans” terminal on the chime.
This creates a circuit that allows the Nest Hello to trigger the chime without overloading it.
Secure and Close
Tuck the connector inside the chime box and close the cover. Make sure no wires are pinched.
If you’re unsure about this step, Nest’s support site has detailed diagrams, or you can call their support line for guidance.
Step 5: Mount the Nest Hello
Now for the fun part—putting up your new smart doorbell.
Choose the Right Location
The Nest Hello should be installed at about chest height (around 48–52 inches from the ground) and angled slightly downward. This gives the camera a clear view of visitors’ faces and any packages left at the door.
Avoid placing it in direct sunlight or under bright porch lights, as this can cause glare or wash out the image.
Attach the Mounting Plate
Hold the mounting plate 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, stucco, or concrete, use the included drill bit to create pilot holes.
Secure the plate with the provided screws. Make sure it’s tight—this holds the entire doorbell.
Connect the Wires
Take the two wires from your wall and connect them to the back of the Nest Hello. It doesn’t matter which wire goes where—the Nest Hello is designed to work either way.
Push the wires into the terminals and tighten the screws. Don’t overtighten—just snug enough to hold the wires securely.
Snap the Doorbell into Place
Align the Nest Hello with the mounting plate and press it firmly until it clicks into place. Give it a gentle tug to make sure it’s secure.
Step 6: Turn the Power Back On
Head back to your breaker panel and turn the power back on. Wait about 30 seconds for the system to reset.
You should hear your chime ring briefly—this means power is restored and the doorbell is receiving electricity.
If nothing happens, double-check your wiring and breaker. If the chime buzzes continuously, the chime connector may not be installed correctly.
Step 7: Set Up the Nest App
The Nest app is your control center for the doorbell. It handles Wi-Fi setup, notifications, and customization.
Download and Open the App
If you haven’t already, download the Nest app on your smartphone. Create an account or log in if you have one.
Add a New Device
Tap the “+” icon and select “Doorbells.” Choose “Nest Hello” when prompted.
The app will ask you to scan the QR code on the back of your doorbell. Hold your phone close until it recognizes the code.
Connect to Wi-Fi
Follow the on-screen instructions to connect your doorbell to your home Wi-Fi network. Remember: Nest Hello only works on 2.4 GHz networks. If your router broadcasts both 2.4 GHz and 5 GHz, make sure you’re connecting to the 2.4 GHz band.
Enter your Wi-Fi password when prompted. The app will test the connection and confirm when it’s successful.
Test the Doorbell
Once connected, the app will guide you through a quick test. Press the doorbell button—you should see live video and hear audio through your phone.
Adjust the camera angle if needed by loosening the mounting plate slightly and tilting the doorbell.
Step 8: Customize Your Settings
Now that your Nest Hello is online, it’s time to personalize it.
Set Up Motion Zones
In the app, go to “Settings” > “Motion sensing” > “Activity zones.” Draw zones on the camera view to specify where you want alerts (e.g., the walkway or driveway). This reduces false alarms from passing cars or animals.
Adjust Notification Preferences
Choose when and how you want to be alerted. You can get notifications for all motion, only people, or only rings. You can also silence alerts during certain hours.
Enable Familiar Face Alerts (Optional)
If you have a Nest Aware subscription, you can enable Familiar Face Alerts. The doorbell will learn to recognize family members and regular visitors, sending personalized notifications like “Mom is at the door.”
Set Up Package Alerts
Nest Hello can detect when a package is delivered. Enable this feature in the app to get alerts when a box is left at your door.
Step 9: Final Testing and Troubleshooting
Before you call it a day, run through a few tests to ensure everything works perfectly.
Test the Video and Audio
Open the live view in the app and check the video quality. It should be clear, even at night (thanks to night vision). Tap the microphone icon to test two-way audio—speak and listen for clarity.
Test Motion Detection
Walk in front of the doorbell to trigger motion alerts. Make sure you receive notifications on your phone and that the video clip captures the event.
Test the Chime
Press the doorbell button and confirm your indoor chime rings. If it doesn’t, revisit the chime connector installation.
Common Issues and Fixes
