Before you even unbox your Nest Hello, it’s crucial to confirm that your home is compatible. Installing a smart doorbell on incompatible wiring can lead to poor performance, frequent disconnections, or even damage to the device.
Check Your Existing Doorbell Wiring
The Nest Hello requires a wired connection to function properly. It does not support battery-only operation. Start by removing your current doorbell button (we’ll cover how to do this safely in the next step) and inspecting the wires behind it. You should see two low-voltage wires—typically labeled “Front” and “Trans” or “Transformer.” These carry power from your home’s transformer to the doorbell.
If you only have one wire or no wires at all, the Nest Hello won’t work unless you install wiring. In that case, you may need to consult an electrician or consider a wireless alternative like the Nest Hello Battery (a different model).
Verify Your Transformer’s Voltage and Power
The Nest Hello needs a transformer that outputs between 16 and 24 volts AC (alternating current) and at least 30 volt-amperes (VA) of power. Most older homes have transformers that meet these requirements, but it’s best to check.
To find your transformer, look near your doorbell chime inside the house—it’s usually a small metal box mounted on a wall or ceiling. The voltage and VA rating are often printed on the side. If you can’t find it or the specs are unclear, use a multimeter to test the voltage at the doorbell wires (with the power on). A reading between 16V and 24V confirms compatibility.
Tip: If your transformer is below 16V or under 30VA, you’ll need to upgrade it. This is a job for a licensed electrician, as it involves working with household wiring.
Ensure You Have a Stable Wi-Fi Connection
The Nest Hello streams video and sends alerts over Wi-Fi, so a strong, reliable internet connection is essential. The device supports 2.4 GHz networks (required) and 5 GHz networks (optional, for better performance). Make sure your router is within range of your front door—ideally within 30 to 50 feet.
You can test your Wi-Fi signal strength using a smartphone or tablet. Stand at your front door and check the signal bars. If it’s weak, consider using a Wi-Fi extender or mesh network system to boost coverage.
Step 2: Gather Your Tools and Materials
Having the right tools on hand will make the installation process faster and safer. Here’s what you’ll need:
- Screwdriver (Phillips and flathead): For removing the old doorbell and mounting the Nest Hello.
- Voltage tester or multimeter: To confirm power is off and check transformer voltage.
- Drill and drill bits (optional): If you need to make new mounting holes or run wires.
- Wire strippers (optional): In case you need to trim or re-strip the existing wires.
- Pencil or marker: For marking drill points.
- Level: To ensure the doorbell is mounted straight.
- Smartphone or tablet: For setup via the Google Home app.
- Nest Hello installation kit: Includes the doorbell, mounting plate, screw anchors, wire extenders, and chime connector.
Pro Tip: Keep a small bowl or container nearby to hold screws and small parts so they don’t get lost during installation.
Step 3: Turn Off Power and Remove the Old Doorbell
Safety is paramount when working with electrical components. Even though doorbell systems use low voltage, it’s still important to turn off the power to avoid accidental shocks or short circuits.
Locate and Turn Off the Circuit Breaker
Go to your home’s main electrical panel (breaker box) and find the circuit that controls your doorbell. It may be labeled “Doorbell,” “Chime,” or “Front Door.” If not, turn off individual breakers one by one and test the doorbell until it stops working.
Once you’ve identified the correct breaker, switch it to the “Off” position. For extra safety, use a voltage tester at the doorbell wires to confirm no power is flowing.
Remove the Old Doorbell Button
Use a screwdriver to remove the screws holding your existing doorbell button to the wall. Gently pull the button away from the wall to expose the two wires underneath. Don’t disconnect them yet—just make sure they’re long enough to reach the new mounting plate.
If the wires are too short, use the wire extenders included in the Nest Hello kit. Simply twist the existing wire into one end of the extender and the other end into the Nest Hello’s terminal.
Inspect and Prepare the Wiring
Check the condition of the wires. If they’re frayed, corroded, or damaged, trim them back and strip about 1/4 inch of insulation using wire strippers. Clean, exposed copper ensures a solid connection.
Important: Never let the two bare wires touch each other while power is on—this can cause a short circuit.
Step 4: Install the Nest Hello Mounting Plate
The mounting plate is the backbone of your Nest Hello installation. It holds the doorbell securely and connects it to the wiring.
Position the Mounting Plate
Hold the mounting plate against the wall where you want to install the doorbell. Ideally, it should be at eye level (about 48 to 52 inches from the ground) and centered on the doorframe.
Use a level to make sure the plate is straight. Mark the screw holes with a pencil.
Drill Pilot Holes (If Needed)
If you’re mounting into brick, stucco, or concrete, drill pilot holes using a masonry bit. For wood or siding, you can usually screw directly into the surface.
Insert the plastic screw anchors (included) into the holes if your wall material requires them.
Secure the Mounting Plate
Align the plate with the holes and screw it into place using the provided screws. Make sure it’s tight and flush against the wall.
Tip: If your doorbell is near a corner or uneven surface, use the included wedge kit to angle the doorbell for a better view of visitors.
Step 5: Connect the Wires and Attach the Doorbell
Now it’s time to connect your Nest Hello to the power source.
Connect the Wires to the Terminal
The Nest Hello has two terminal screws labeled “Front” and “Trans.” It doesn’t matter which wire goes where—the device is polarity-independent.
Loosen the screws, insert one wire into each terminal, and tighten the screws to secure them. Give the wires a gentle tug to ensure they’re firmly connected.
Attach the Doorbell to the Mounting Plate
Slide the Nest Hello onto the mounting plate until it clicks into place. The device should sit flush and feel secure.
Note: The Nest Hello has a built-in magnet that helps align it properly. You’ll hear a soft click when it’s seated correctly.
Step 6: Turn Power Back On and Test the Doorbell
With the doorbell installed, it’s time to restore power and see if it works.
Restore Power at the Breaker
Go back to your electrical panel and turn the doorbell circuit back on. Wait about 30 seconds for the system to power up.
Check for Power and Chime Activation
Press the Nest Hello button. You should hear your indoor chime ring. If it doesn’t, double-check the wiring connections and ensure the chime unit is compatible.
If your chime doesn’t work, you may need to install the Nest Chime Connector (included in the kit). This small device plugs into your existing chime and ensures compatibility with the Nest Hello.
Look for the Status Light
The Nest Hello has a status light on the front. When powered on, it will glow solid white, then pulse white as it connects to Wi-Fi. If the light is off or flashing red, there may be a power or connection issue (see troubleshooting section).
Step 7: Set Up the Nest Hello in the Google Home App
The final step is configuring your doorbell through the Google Home app. This is where you connect it to Wi-Fi, customize settings, and enable smart features.
Download and Open the Google Home App
If you don’t already have it, download the Google Home app from the Apple App Store or Google Play Store. Sign in with your Google account.
Start the Setup Process
Tap the “+” icon in the top-left corner, then select “Set up device” > “New device.” Choose your home and follow the on-screen prompts.
When prompted, scan the QR code on the back of the Nest Hello using your phone’s camera. This links the device to your account.
Connect to Wi-Fi
Select your Wi-Fi network and enter the password. The app will guide you through connecting the doorbell to your network. This may take a minute or two.
Tip: If the connection fails, move closer to your router or temporarily use a mobile hotspot to complete setup.
Configure Settings and Preferences
Once connected, you can customize features like:
- Motion zones: Define areas where you want to receive alerts (e.g., driveway but not sidewalk).
- Package detection: Get notified when a package is delivered.
- Quiet time: Silence notifications during specific hours.
