Step 1: Check Compatibility
Not all doorbell systems can power a Nest Doorbell wired. Before you start, make sure your current setup is compatible.
Check Your Transformer Voltage
The Nest Doorbell wired requires a transformer that outputs between 8 and 24 volts AC. Most older doorbells use 16V, which is perfect. But if your transformer is too low (like 6V), the doorbell won’t get enough power. If it’s too high (over 24V), you could damage the device.
To check:
- Turn off the power at the breaker.
- Remove your old doorbell from the wall.
- Locate the two wires connected to it.
- Use a multimeter or voltage tester to measure the voltage between the wires.
If you don’t have a tester, you can usually find the transformer near your doorbell—often in the basement, garage, or near your furnace. Look for a small box with wires coming out. The voltage should be printed on it.
Check Your Chime Type
The Nest Doorbell wired works with both mechanical chimes (the traditional “ding-dong” kind) and digital chimes (electronic ones with multiple sounds).
If you have a mechanical chime, you’ll need to use the included chime connector. This small device connects to your chime’s terminals and tells the doorbell when to ring.
Digital chimes usually work without extra hardware, but some models may require a resistor. Check the Nest support page for your specific chime model.
Wi-Fi Requirements
Your home Wi-Fi must support 2.4 GHz networks. The Nest Doorbell wired does not work with 5 GHz-only networks. Also, make sure your signal is strong at the doorbell location. If Wi-Fi is weak, consider a Wi-Fi extender.
Step 2: Turn Off the Power
Safety first! Working with electricity is no joke.
Locate the Circuit Breaker
Find the breaker that controls your doorbell. It’s usually labeled “doorbell,” “chime,” or “front door.” If you’re not sure, turn off the main breaker to be safe.
Test the Power
Even after turning off the breaker, double-check that the power is off:
- Remove the old doorbell.
- Touch the voltage tester to the two wires.
- If the tester lights up or beeps, the power is still on—find the correct breaker.
Never skip this step. A small shock won’t hurt the doorbell, but it could hurt you.
Step 3: Remove the Old Doorbell
Now it’s time to take down your existing doorbell.
Unscrew the Old Unit
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull it away from the wall. You’ll see two wires connected to the back.
Disconnect the Wires
Loosen the screws or terminals holding the wires. Carefully pull the wires free. Don’t let them fall back into the wall—tape them to the wall or hold them with a helper.
If the wires are too short, you may need to strip a little more insulation to expose fresh copper. Use wire strippers to remove about 1/4 inch of insulation.
Inspect the Mounting Area
Check the wall surface. Is it flat? Is there enough space for the Nest Doorbell? If the wall is uneven or the doorbell needs to be angled, you may need the wedge or corner mount.
Step 4: Install the Mounting Plate
The mounting plate holds the Nest Doorbell securely and connects the wires.
Choose the Right Mount
– Use the **standard mount** if your doorbell is flush with the wall.
– Use the **wedge mount** if you want to angle the doorbell toward the walkway.
– Use the **corner mount** if installing on a corner.
Attach the chosen mount to the mounting plate using the small screws provided.
Position the Mount
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.
Drill Pilot Holes
If you’re drilling into wood or drywall, drill pilot holes slightly smaller than the screws. This prevents cracking. If mounting into brick or concrete, use a masonry bit and wall anchors.
Secure the Mount
Line up the mounting plate with the holes and screw it into place. Make sure it’s tight and level.
Step 5: Connect the Wires
Now for the electrical part—don’t worry, it’s simple.
Identify the Wires
You should have two wires: one from the transformer and one from the chime. It doesn’t matter which is which—Nest Doorbell wired is not polarity-sensitive.
Connect to the Mounting Plate
On the back of the mounting plate, you’ll see two terminals labeled “Front” and “Trans.”
– Insert one wire into the “Front” terminal.
– Insert the other into the “Trans” terminal.
– Tighten the screws to secure the wires.
Make sure the bare copper is fully inside and not touching the other terminal.
Use the Chime Connector (If Needed)
If you have a mechanical chime, connect the chime connector:
- Open your chime box (usually behind a cover).
- Find the two terminals where the doorbell wires connect.
- Disconnect the wires and connect them to the chime connector.
- Connect the chime connector to the chime terminals.
- Secure the connector inside the chime box.
This tells the Nest Doorbell when to ring the chime.
Step 6: Attach the Nest Doorbell
With the mount and wires ready, it’s time to attach the doorbell.
Align the Doorbell
Hold the Nest Doorbell against the mounting plate. The pins on the back should align with the slots on the plate.
Slide and Lock
Gently slide the doorbell down until it clicks into place. You should feel it lock securely.
Check the Fit
Make sure the doorbell is level and doesn’t wobble. If it’s loose, double-check the mount and screws.
Step 7: Turn the Power Back On
Now that everything is connected, restore power.
Flip the Breaker
Go back to the circuit breaker and turn the doorbell circuit back on.
Wait for the Light
The Nest Doorbell will power on and show a light ring. It may take 30–60 seconds to fully boot up.
If the light doesn’t come on, turn the power off and check your wiring.
Step 8: Set Up the Nest Doorbell in the Google Home App
The Google Home app is your control center for the Nest Doorbell.
Download the App
If you don’t have it, download the Google Home app from the App Store or Google Play.
Sign In or Create an Account
Use your Google account to sign in. If you don’t have one, create it—it’s free.
Add the Doorbell
- Open the app and tap the “+” icon.
- Select “Set up device.”
- Choose “New device.”
- Follow the prompts to scan the QR code on the back of the doorbell.
If you can’t scan the code, you can enter the serial number manually.
Connect to Wi-Fi
The app will ask for your Wi-Fi network and password. Make sure you’re on a 2.4 GHz network. The doorbell will connect and download updates if needed.
Name Your Doorbell
Give it a name like “Front Door” or “Porch.” This helps if you have multiple cameras.
Set Up Motion and Chime Settings
Choose when you want alerts:
- People, packages, vehicles, or all motion
- Ring the chime when pressed
- Customize notification sounds
You can also set activity zones to focus on specific areas, like your driveway or walkway.
Test the Doorbell
Press the button on the doorbell. Your phone should get a notification, and the chime should ring.
If the chime doesn’t ring, check the chime connector or chime settings in the app.
Step 9: Final Adjustments and Tips
Your Nest Doorbell is installed, but a few tweaks can make it even better.
Adjust the Angle
If the view is too high or low, remove the doorbell and adjust the mount. The wedge mount can tilt the camera up to 15 degrees.
Secure Loose Wires
Use wire clips or electrical tape to secure any loose wires to the wall. This keeps them from getting damaged.
Update Firmware
The app will notify you if a firmware update is available. Keep your doorbell updated for the best performance and security.
Check Night Vision
At night, the doorbell uses infrared LEDs for clear video. Make sure nothing is blocking the lens or IR sensors.
