Before you begin installing your Nest Hello, it’s important to gather all the necessary tools and materials. Having everything ready will make the process smoother and help avoid frustrating mid-installation trips to the hardware store.
Here’s a checklist of what you’ll need:
- Nest Hello video doorbell kit: Includes the doorbell, mounting plate, chime connector, screwdriver, and wire labels.
- Screwdriver (Phillips head): For removing your old doorbell and securing the new mount.
- Drill and drill bits (optional): Only if you need to create new mounting holes or run wires.
- Voltage tester (recommended): To confirm power is off and check transformer output.
- Smartphone or tablet: With the Google Home app installed and updated.
- Wi-Fi network: 2.4 GHz or 5 GHz (Nest Hello supports both, but 2.4 GHz offers better range through walls).
- Ladder (if needed): For reaching high doorbell locations.
It’s also a good idea to read through the entire installation process before starting. This helps you understand the steps and identify any potential challenges unique to your home setup.
Step 1: Check Compatibility
Not every home is ready for the Nest Hello right out of the box. To ensure a smooth installation, you need to verify that your existing doorbell system meets the device’s electrical requirements.
Check Your Doorbell Wiring
The Nest Hello requires a wired connection to function. It cannot run on batteries alone, so you must have existing low-voltage doorbell wiring (typically two wires) running from your doorbell button to the chime inside your home.
If you currently have a wired doorbell, you’re likely good to go. But if your doorbell is wireless or battery-powered, you’ll need to install wiring first—or consider a battery-powered alternative like the Ring Video Doorbell.
Test Your Transformer Voltage
The Nest Hello needs a transformer that outputs between 16 and 24 volts AC (alternating current) and at least 30VA (volt-amperes). Most older homes have transformers in this range, but it’s worth checking.
To test:
- Turn off power at the breaker.
- Remove your existing doorbell button.
- Use a multimeter or voltage tester to measure the voltage across the two wires.
- If the reading is below 16V or above 24V, you may need to replace the transformer.
If you’re unsure about your transformer, consult an electrician. Installing the Nest Hello on an incompatible system can damage the device or cause it to malfunction.
Check Your Chime Type
The Nest Hello works with most mechanical (ding-dong) and digital chimes. However, if you have a complex multi-tone chime or a chime that uses a proprietary system (like some older Ring or SkyBell models), you may need to bypass it or use the included chime connector.
The chime connector is a small device that goes inside your chime box and ensures the Nest Hello can trigger the sound properly. We’ll cover how to install it later.
Step 2: Turn Off the Power
Safety should always come first when working with electrical components. Even though doorbell systems use low voltage, there’s still a risk of shock or short-circuiting if wires are mishandled.
Locate Your Circuit Breaker
Find the breaker that controls your doorbell circuit. It’s often labeled “doorbell,” “chime,” or “front door.” If you can’t find it, turn off the main breaker to be safe.
Test the Power
After turning off the breaker, press your existing doorbell button to confirm the chime doesn’t sound. You can also use a non-contact voltage tester near the wires to ensure no current is flowing.
Never assume the power is off—always double-check.
Step 3: Remove Your Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell button.
Unscrew the Old Button
Use a Phillips head screwdriver to remove the screws holding your current doorbell in place. Gently pull the button away from the wall to expose the wires.
Label the Wires
Before disconnecting anything, label the two wires (e.g., “Front” and “Trans”) using the included wire labels or tape. This helps you reconnect them correctly later.
Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. Keep them separated so they don’t touch each other or the wall.
Set the old doorbell aside—you won’t need it anymore.
Step 4: Install the Chime Connector (If Needed)
The chime connector is a small, rectangular device that ensures your indoor chime works with the Nest Hello. It’s especially useful if your chime doesn’t respond properly to the new doorbell.
Locate Your Chime Box
The chime is usually located in a basement, utility room, or hallway ceiling. Open the cover to access the wiring.
Connect the Chime Connector
- Disconnect the two wires from the “Front” terminals on the chime.
- Connect those wires to the input terminals on the chime connector.
- Use the included wire nuts to connect the chime connector’s output wires to the chime’s “Front” terminals.
- Secure the chime connector inside the chime box with tape or a zip tie.
This step ensures the Nest Hello can trigger your chime reliably. If you skip it and your chime doesn’t work, you’ll need to come back and install it.
Step 5: Mount the Nest Hello
Now it’s time to install the Nest Hello itself.
Choose the Right Mounting Plate
The Nest Hello comes with two mounting plates: a flat one and a wedge-shaped one for angled installations. Use the wedge if your doorbell is mounted on a corner or needs to be tilted toward the walkway.
Position the Mounting Plate
Hold the plate against the wall where you want to install the doorbell. The ideal height is between 48 and 60 inches from the ground—this ensures clear facial recognition and prevents tampering.
Use a level to make sure the plate is straight. Mark the screw holes with a pencil.
Drill Holes (If Necessary)
If your old doorbell used the same holes, you can reuse them. Otherwise, drill new pilot holes using a drill bit slightly smaller than the included wall anchors.
Insert the wall anchors for a secure fit, especially if you’re mounting on brick, stucco, or concrete.
Attach the Mounting Plate
Secure the plate to the wall using the provided screws. Make sure it’s tight and level.
Connect the Wires
Take the two labeled wires from your wall and connect them to the terminals on the back of the Nest Hello. It doesn’t matter which wire goes where—the Nest Hello is non-polarized.
Tighten the terminal screws to secure the wires.
Attach the Doorbell
Align the Nest Hello with the mounting plate and press it firmly into place. You’ll hear a click when it’s secure.
Step 6: Restore Power and Test
With the Nest Hello installed, it’s time to turn the power back on and test the system.
Turn On the Breaker
Go back to your circuit breaker and turn the doorbell circuit back on.
Check the Chime
Press the Nest Hello button. Your indoor chime should sound. If it doesn’t, double-check the chime connector installation or wiring.
Look for the Status Light
The Nest Hello has a status light on the front. When powered correctly, it will glow solid green. If it’s blinking or off, there may be a wiring or power issue.
Step 7: Set Up the Nest Hello in the Google Home App
The final step is configuring your Nest Hello using the Google Home app. This is where you connect it to Wi-Fi, customize settings, and enable smart features.
Download the Google Home App
If you don’t already have it, download the Google Home app from the App Store (iOS) or Google Play (Android). Sign in with your Google account.
Start the Setup Process
- Open the app and tap the “+” icon to add a new device.
- Select “Set up device” and then “New device.”
- Choose your home and location (e.g., “Front Door”).
- The app will search for nearby devices. When the Nest Hello appears, tap it.
Scan the QR Code
Use your phone’s camera to scan the QR code on the back of the Nest Hello. This links the device to your account.
