Before you touch a single wire, make sure you have the right tools and information. Rushing into installation without preparation can lead to frustration—or worse, electrical hazards.
Tools and Materials
- Google Nest Hello doorbell (wired version)
- Screwdriver (Phillips head)
- Drill (optional, for new mounting holes)
- Voltage tester (non-contact type recommended)
- Wire strippers (if you need to trim or re-strip wires)
- Pencil or marker
- Level (to ensure the doorbell is straight)
- Smartphone or tablet with the Google Home app installed
- Wi-Fi network name and password
Check Your Doorbell System Compatibility
Not all doorbells are created equal. The Nest Hello requires a wired connection and specific electrical specs to work properly.
Your existing doorbell system must meet these requirements:
- Voltage: 16–24 volts AC
- Transformer rating: At least 30VA (volt-amperes)
- Wiring: Two low-voltage wires connected to the doorbell button
If you’re unsure about your transformer, look near your furnace, basement, or utility closet. It’s usually a small metal box with wires coming out. You can also check your old doorbell’s manual or contact an electrician.
Pro Tip: If your current system doesn’t meet these specs, you may need to upgrade your transformer. Google sells a compatible transformer, or you can hire an electrician to install one.
Download the Google Home App
The Google Home app is essential for setup. It guides you through connecting your doorbell to Wi-Fi, pairing it with your chime, and customizing settings.
Download it from the Apple App Store or Google Play Store. Make sure your phone is connected to your home Wi-Fi network before starting.
Step 1: Turn Off the Power
Safety first! Working with electricity is no joke. Even low-voltage doorbell wires can cause shocks or damage your new device if mishandled.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (breaker box). Look for the breaker labeled “doorbell,” “chime,” or “HVAC.” If you can’t find it, turn off the main breaker to be safe.
Test the Wires
After turning off the power, remove your old doorbell from the wall. Use a non-contact voltage tester to touch the exposed wires. If the tester beeps or lights up, the power is still on—double-check your breaker.
Important: Never assume the power is off. Always test.
Step 2: Remove Your Old Doorbell
Now that the power is off, it’s time to take down the old unit.
Unscrew the Old Doorbell
Use a Phillips screwdriver to remove the screws holding your existing doorbell to the wall. Gently pull the doorbell away from the wall. You should see two wires connected to the back.
Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. Don’t let them fall back into the wall. You can tape them to the wall or hold them with a clip to keep them accessible.
Inspect the Wiring
Check the condition of the wires. If they’re frayed, corroded, or too short, you may need to strip fresh ends or extend them. Use wire strippers to expose about 1/4 inch of copper if needed.
Step 3: Prepare the Nest Hello Doorbell
Your Nest Hello comes with a mounting plate, screws, and optional accessories. Let’s get it ready.
Choose the Right Mounting Plate
The Nest Hello includes a standard mounting plate. If your doorbell is on a corner or you want a better viewing angle, consider using the optional wedge or trim kit (sold separately).
- Wedge Kit: Angles the doorbell 15° left or right for better coverage.
- Trim Kit: Fits narrow spaces or covers large holes from old doorbells.
Attach the wedge or trim to the mounting plate before installing.
Thread the Wires Through the Plate
Feed the two doorbell wires through the center hole of the mounting plate. This keeps them organized and prevents strain on the connections.
Step 4: Mount the Nest Hello to the Wall
Now it’s time to secure the doorbell to your wall.
Position the Mounting Plate
Hold the mounting plate (with wires threaded through) 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 using a wedge or trim, make sure it’s angled correctly for optimal camera view.
Drill Pilot Holes (If Needed)
If you’re drilling into brick, stucco, or concrete, use a masonry bit to drill pilot holes. For wood or drywall, a small drill bit works fine.
Secure the Mounting Plate
Align the plate with the marks and screw it into place using the provided screws. Don’t overtighten—this can crack the plate or damage the wall.
Step 5: Connect the Wires
This is the moment of truth—connecting your Nest Hello to power.
Identify the Wire Terminals
On the back of the Nest Hello, you’ll see two terminals labeled “Front” and “Trans.” It doesn’t matter which wire goes where—Nest Hello is polarity-independent.
Attach the Wires
Loosen the terminal screws, insert one wire into each terminal, and tighten the screws. Make sure the bare copper is fully inserted and not touching the other terminal.
Pro Tip: If the wires are too short, you can use wire nuts or extend them with additional low-voltage wire.
Secure the Doorbell to the Plate
Align the Nest Hello with the mounting plate and press it firmly until it clicks into place. The magnetic latch will hold it securely.
Step 6: Turn the Power Back On
Now that everything is connected, it’s time to restore power.
Flip the Breaker
Go back to your electrical panel and turn the breaker back on. Wait a few seconds for the system to power up.
Check for Lights
The Nest Hello should light up with a white ring. If it doesn’t, double-check your wiring and breaker.
Step 7: Set Up the Nest Hello with the Google Home App
The hardware is in place—now let’s get it connected to your home network.
Open the Google Home App
Launch the app on your phone. If you don’t have a home set up, follow the prompts to create one.
Tap “Add” or “+”
Select “Set up device” and choose “New device.” The app will search for nearby Nest devices.
Scan the QR Code
Hold your phone up to the QR code on the back of the Nest Hello. The app will recognize it and begin setup.
Connect to Wi-Fi
Select your home Wi-Fi network and enter the password. Nest Hello supports 2.4 GHz networks (required) and 5 GHz (optional for better performance).
Note: If you only have a 5 GHz network, you’ll need to enable 2.4 GHz or use a dual-band router.
Name Your Doorbell
Give your doorbell a name, like “Front Door” or “Main Entrance.” This helps if you have multiple Nest devices.
Set Up Motion and Notification Zones
The app will guide you to draw zones where you want motion detection. For example, you might want alerts when someone approaches the door but ignore the sidewalk.
Pair with Your Chime
If you have a mechanical or digital chime, the app will detect it and pair automatically. If not, you can use the Nest Hello’s built-in speaker or a Nest Chime (sold separately).
Test the Doorbell
Press the button on the Nest Hello (or have someone ring it). You should hear the chime and receive a notification on your phone.
Step 8: Adjust Settings and Customize
Now that it’s working, let’s fine-tune it for your lifestyle.
Enable Facial Recognition (Optional)
Nest Hello can learn familiar faces. Go to Settings > Familiar Faces and turn it on. Over time, it will recognize family, friends, and frequent visitors.
Set Activity Zones
Customize which areas trigger alerts. For example, ignore the street but alert when someone steps on the porch.
Adjust Motion Sensitivity
If you’re getting too many alerts, lower the sensitivity. If you’re missing events, increase it.
Enable Package Detection
Nest Hello can notify you when a package is delivered. Turn this on in the app under “Alerts.”
Set Do Not Disturb Hours
Prevent notifications during sleep or quiet hours. You can schedule this in the app.
