Check Your Existing Doorbell System
Not all doorbell systems are compatible with the Nest Doorbell Wired. Here’s what you need to know:
– Transformer Voltage: Your doorbell transformer should output between 8V and 24V AC. Most modern doorbells fall in the 16V–24V range, which is ideal. If your transformer is too low (under 8V), the Nest may not power on properly.
– Wiring: You need at least two wires connected to your existing doorbell button (typically labeled “front” and “trans”). These carry power from the transformer to the chime and back.
– Chime Type: The Nest Doorbell Wired works with both mechanical and digital chimes. However, if you have a mechanical chime (the kind with physical bells or slappers), you may need to install a Nest Chime Connector to ensure the chime rings reliably. We’ll cover this in detail later.
Tip: If you’re unsure about your doorbell’s voltage, use a multimeter to test the wires at the button. Or, check the label on your transformer—usually located in your basement, garage, or utility closet.
Step 1: Turn Off Power at the Breaker
Safety first! Even though doorbell wires carry low voltage, it’s still important to turn off the power to avoid short circuits or damage to your system.
Locate Your Electrical Panel
Go to your home’s main electrical panel (breaker box). Look for the circuit labeled “doorbell,” “chime,” or something similar. If there’s no label, you may need to test circuits by turning them off one at a time and checking if your doorbell stops working.
Switch Off the Correct Breaker
Once you’ve identified the right breaker, flip it to the “OFF” position. Use a non-contact voltage tester at the doorbell button to confirm there’s no power. The tester should not light up or beep.
⚠️ Never skip this step. Even low-voltage systems can cause damage or injury if mishandled.
Step 2: Remove Your Old Doorbell Button
Now that the power is off, it’s time to remove your existing doorbell button.
Unscrew the Faceplate
Use a Phillips-head screwdriver to remove the screws holding the old doorbell button to the wall. Gently pull the button away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back of the button. Loosen the terminal screws and carefully pull the wires free. Don’t let them fall back into the wall—use electrical tape to secure them to the wall or hold them with a clip.
Tip: Take a photo of the wiring before disconnecting. This will help you remember which wire goes where when installing the Nest.
Inspect the Wires
Check the condition of the wires. If they’re frayed, corroded, or too short, you may need to strip back a small section (about 1/4 inch) using wire strippers. Clean, exposed copper ensures a solid connection.
Step 3: Prepare the Nest Doorbell Wired
Your Nest Doorbell Wired comes with a mounting plate and two wire leads. Let’s get it ready for installation.
Attach the Wire Leads
The Nest includes two short wires (called “pigtails”) that connect to your home’s existing wires. Strip about 1/4 inch of insulation from the ends of both your home’s wires and the Nest pigtails.
Twist the exposed copper ends of one home wire with one pigtail, then secure them with a wire nut. Repeat with the second set. Make sure the connections are tight and no bare wire is exposed.
Secure the Connections
Wrap each wire nut with electrical tape for extra security. This prevents them from loosening over time due to vibration or weather.
Tip: If your wires are too short to reach comfortably, you can splice in short extensions using additional low-voltage wire and wire nuts.
Step 4: Mount the Nest Doorbell
Now it’s time to attach the doorbell to your wall.
Position the Mounting Plate
Hold the Nest mounting plate against the wall where you want to install the doorbell. Make sure it’s level using a spirit level or the level tool in your smartphone.
Mark the screw holes with a pencil.
Drill Pilot Holes
Use a 3/16” drill bit to create pilot holes at the marked spots. This prevents the wall from cracking, especially if you’re mounting into brick, stucco, or concrete.
Secure the Plate
Insert wall anchors if needed (included in the box for drywall or masonry). Then, screw the mounting plate into place using the provided screws.
Attach the Doorbell
Slide the Nest Doorbell Wired onto the mounting plate until it clicks into place. Give it a gentle tug to ensure it’s secure.
Adjust the Viewing Angle (Optional)
If your doorbell is mounted too high or at an awkward angle, use the included wedge or trim kit to adjust the camera’s field of view. This ensures you capture visitors’ faces clearly and avoid blind spots.
Tip: The ideal mounting height is about 48 inches (4 feet) from the ground. This allows most adults to be seen clearly in the camera feed.
Step 5: Restore Power and Test the Doorbell
With the doorbell mounted and wired, it’s time to turn the power back on and test the system.
Flip the Breaker Back On
Return to your electrical panel and turn the doorbell circuit back on.
Wait for the Doorbell to Power Up
The Nest Doorbell will take about 30–60 seconds to boot up. You’ll see a light ring on the front—it will pulse white during startup.
Test the Chime
Press the doorbell button. Your indoor chime should ring. If it doesn’t, don’t panic—this is common with mechanical chimes and can usually be fixed with a Nest Chime Connector.
Check the Light Ring
The light ring indicates status:
– Solid white: Ready to set up
– Blinking white: Connecting to Wi-Fi
– Solid green: Connected and working
If the light stays off or flashes red, there may be a power or wiring issue (see troubleshooting section).
Step 6: Set Up the Nest Doorbell in the Google Home App
Now that the hardware is installed, it’s time to connect your doorbell to your Wi-Fi network and configure settings.
Download and Open the Google Home App
If you haven’t already, download the Google Home app from the App Store (iOS) or Google Play (Android). 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 from the list.
Scan the QR Code
Hold your phone up to the QR code on the back of the Nest Doorbell. The app will detect it and begin pairing.
Connect to Wi-Fi
Select your Wi-Fi network and enter the password. The doorbell supports both 2.4 GHz and 5 GHz bands, but 5 GHz is recommended for faster streaming and better performance.
Tip: Make sure your phone is connected to the same Wi-Fi network you want the doorbell to use.
Name Your Doorbell
Give your doorbell a name, like “Front Door” or “Main Entrance.” This helps if you have multiple Nest devices.
Configure Motion and Alert Settings
Choose what types of alerts you want:
– Person alerts
– Package detection
– Vehicle detection
– Motion zones (to focus on specific areas like your walkway)
You can also set quiet hours to avoid notifications at night.
Test Two-Way Audio
Tap the microphone icon in the live view and speak. You should hear your voice through the doorbell’s speaker. Ask someone to press the button and test the audio from their side.
Step 7: Install the Nest Chime Connector (If Needed)
If your indoor chime doesn’t ring after installation, you likely need a Nest Chime Connector—especially if you have a mechanical chime.
What Is a Nest Chime Connector?
The Chime Connector is a small device that plugs into your chime box and communicates wirelessly with the doorbell. It ensures the chime rings reliably, even with low-power systems.
Where to Install It
Locate your indoor chime box—usually near the front door or in a hallway. Open the cover to access the wiring.
Connect the Chime Connector
The Chime Connector has two wires that connect to the same terminals as your chime (typically labeled “Front” and “Trans”). Disconnect the existing wires, attach them to the Chime Connector, and secure with wire nuts.
Power the Chime Connector
Plug the Chime Connector into a nearby electrical outlet. It needs power to communicate with the doorbell.
Pair with the Doorbell
Open the Google Home app, go to your doorbell settings, and follow the prompts to pair the Chime Connector. The app will guide you through the process.
Once paired, press the doorbell button—the chime should ring clearly.
