Step 1: Turn Off the Power
Safety first! Working with electricity can be dangerous if you’re not careful. Even though doorbell circuits are low voltage, they can still give you a shock or damage your new device if mishandled.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for a breaker labeled “doorbell,” “chime,” or something similar. If there’s no label, you may need to test each one.
Turn Off the Correct Breaker
Flip the breaker to the “off” position. To confirm it’s off, go to your existing doorbell and press the button. If the chime doesn’t sound, the power is off. If it still rings, turn off additional breakers until it stops.
> 💡 Pro Tip: Use a non-contact voltage tester near the doorbell wires after turning off the breaker. If the tester beeps or lights up, the power is still on—double-check your breaker.
Leave a Note
Tape a note to the breaker panel saying “Do not turn on—working on doorbell.” This prevents someone else from accidentally restoring power while you’re working.
Step 2: Check Compatibility
Not all homes are ready for a smart doorbell. Your existing doorbell system must meet certain electrical requirements for the Google Nest Doorbell (wired) to work properly.
Check Transformer Voltage and Power
The Nest Doorbell (wired) requires:
– A transformer that outputs **16–24 volts AC**
– At least **20 volt-amperes (VA)** of power
Most older doorbells use 8–16V transformers, which are too weak. If your transformer is under 16V or under 20VA, your doorbell may not charge properly or could behave erratically.
How to Find Your Transformer
The transformer is usually located:
– Inside the doorbell chime box (inside your home)
– Near the furnace or in the basement
– In the attic or garage
Open the chime box and look for a small rectangular device with wires connected to it. It often has labels like “16V” or “24V.”
Test the Voltage (Optional but Recommended)
Use a multimeter to test the voltage across the doorbell wires:
1. Set the multimeter to AC voltage (V~).
2. Touch the probes to the two doorbell wires.
3. A reading between 16V and 24V means your transformer is compatible.
> ⚠️ Warning: If your transformer is below 16V or you’re unsure, consider upgrading it or using a plug-in transformer (sold separately). Google sells a compatible 16V transformer if needed.
Step 3: Remove Your Old Doorbell
Now that the power is off and you’ve confirmed compatibility, it’s time to remove the old doorbell.
Unscrew the Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away from the wall.
Disconnect the Wires
You’ll see two wires connected to the back of the doorbell. Loosen the screws or pull out the wires from the terminals. Be careful not to let the wires fall back into the wall.
> 💡 Pro Tip: Take a photo of the wiring before disconnecting. This helps if you need to reconnect the old doorbell later.
Cap the Wires
Twist a wire nut onto each exposed wire to prevent them from touching each other or the wall. This also keeps them safe until you’re ready to install the new doorbell.
Remove the Old Mounting Plate (if applicable)
If your old doorbell had a mounting plate, unscrew and remove it. You’ll be installing the new Google mounting bracket in the next step.
Step 4: Install the Mounting Bracket
The mounting bracket holds your Google Doorbell securely to the wall. It also helps align the device properly for the best camera angle.
Position the Bracket
Hold the new mounting bracket against the wall where you want to install the doorbell. Use a level to make sure it’s straight.
Mark the Screw Holes
Use a pencil to mark the locations of the screw holes through the bracket.
Drill Pilot Holes
Drill small pilot holes at the marked spots. This makes it easier to insert the screws and prevents the wall from cracking.
> 💡 Pro Tip: If you’re drilling into brick, stucco, or concrete, use a masonry bit and wall anchors for a secure fit.
Attach the Bracket
Line up the bracket with the pilot holes and secure it with the provided screws. Make sure it’s tight and level.
Step 5: Connect the Wires
Now it’s time to connect your doorbell wires to the new Google Doorbell.
Strip the Wire Ends (if needed)
If the wire ends are frayed or too short, use wire strippers to expose about 1/4 inch of copper. This ensures a good connection.
Connect to the Bracket Terminals
The mounting bracket has two terminals labeled “Front” and “Trans.” It doesn’t matter which wire goes where—Google’s doorbell is designed to work either way.
1. Loosen the terminal screw slightly.
2. Insert the exposed wire into the terminal.
3. Tighten the screw to secure the wire.
> 💡 Pro Tip: If the wires are too short or damaged, use the included jumper wire to extend them. Connect the jumper to the old wire with a wire nut, then attach the jumper to the bracket.
Secure Loose Wires
Tuck any excess wire neatly into the wall cavity so it doesn’t interfere with the doorbell.
Step 6: Attach the Google Doorbell
With the bracket and wires in place, you’re ready to mount the doorbell.
Align the Doorbell
Hold the Google Doorbell so the pins on the back align with the slots on the mounting bracket.
Slide It Into Place
Gently slide the doorbell down onto the bracket until it clicks into place. You should feel it lock securely.
Check the Angle
Look at the doorbell from the side. The camera should point straight ahead or slightly downward to capture visitors’ faces. If it’s tilted too much, adjust the bracket or use the included wedge (if your model has one).
> 💡 Pro Tip: The Nest Doorbell (wired) comes with optional wedge mounts for angled walls. Use them if your doorbell is on a corner or uneven surface.
Step 7: Restore Power and Test
Now that everything is connected, it’s time to turn the power back on and test the doorbell.
Turn the Breaker Back On
Go to your electrical panel and flip the doorbell breaker to the “on” position.
Wait for the Doorbell to Power Up
The doorbell will take 30–60 seconds to boot up. You’ll see a light ring on the front—it will pulse white during startup.
Test the Doorbell
Press the button on the doorbell. You should hear a chime (if your indoor chime is connected) and see the light ring turn solid white.
> 💡 Pro Tip: If nothing happens, double-check your wiring and breaker. Use the voltage tester again to confirm power is reaching the doorbell.
Step 8: Set Up the Google Home App
The final step is connecting your doorbell to your Wi-Fi network and setting it up in the Google Home app.
Download the Google Home App
If you haven’t already, download the Google Home app on your smartphone or tablet (available on iOS and Android).
Sign In to Your Google Account
Open the app and sign in with the Google account you want to use for your smart home devices.
Add a New Device
1. Tap the “+” icon in the top-left corner.
2. Select “Set up device.”
3. Choose “New device.”
4. Follow the on-screen prompts.
