Let’s get started!
What You’ll Need Before You Begin
Before you even think about unscrewing your old doorbell, gather these essentials:
- Your Google Doorbell (Nest Doorbell wired or battery model)
- The included mounting plate and screws
- A Phillips-head screwdriver
- A drill (optional, for harder surfaces like brick or stucco)
- A voltage tester (for wired models)
- Your smartphone with the Google Home app installed
- A stable Wi-Fi network (2.4 GHz band recommended)
- A ladder (if your doorbell is mounted high)
Pro tip: If you’re installing the wired version, make sure you have access to your home’s electrical panel so you can safely turn off power.
Step 1: Check Your Doorbell Compatibility
Not all homes are ready for a smart doorbell right out of the box. Google Doorbell models have specific requirements, especially the wired version.
For Wired Google Doorbell Models
If you’re installing the Nest Doorbell (wired), your existing doorbell system must meet these criteria:
- Transformer voltage: 16–24 volts AC
- Transformer power: At least 30 VA (volt-amperes)
- Existing wiring: Two low-voltage wires connected to your current doorbell button
Most modern homes built after the 1980s meet these standards, but older homes may have underpowered transformers. To check:
- 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 it reads below 16V, you may need a new transformer.
If you’re unsure, consult an electrician. Installing a smart doorbell on an incompatible system can damage the device or cause it to malfunction.
For Battery-Powered Google Doorbell Models
The Nest Doorbell (2nd gen, battery) is more flexible. It doesn’t require existing wiring, but you should still check:
- Your Wi-Fi signal strength at the door (use a Wi-Fi analyzer app if needed)
- That your doorframe or wall can support the mounting plate
- That you have a nearby power source if you plan to use the optional wired charging kit
Even though it’s battery-powered, the doorbell still needs a strong Wi-Fi connection to send alerts and stream video.
Step 2: Turn Off the Power (Wired Models Only)
Safety first! If you’re installing the wired Google Doorbell, you must disconnect power to avoid electric shock or damaging the device.
How to Safely Turn Off Power
- Locate your home’s electrical panel (breaker box).
- Find the circuit labeled “doorbell” or “chime.” If it’s not labeled, turn off the main breaker to be safe.
- Use a non-contact voltage tester at the doorbell button to confirm power is off.
Never skip this step—even low-voltage systems can give a nasty shock or fry your new doorbell.
Step 3: Remove Your Old Doorbell
Now it’s time to take down the old hardware.
For Wired Doorbell Replacement
- Unscrew the existing doorbell button from the wall.
- Gently pull it away to expose the two wires.
- Loosen the terminal screws and disconnect the wires. Label them (e.g., “Front” and “Transformer”) if needed.
- Tuck the wires back into the wall slightly so they don’t fall in.
For Battery Doorbell (No Wiring Needed)
If you’re replacing a wired doorbell with a battery model, you can cap the wires with wire nuts and tuck them into the wall. You won’t need them unless you later switch to a wired setup.
Step 4: Install the Mounting Plate
The mounting plate is the backbone of your Google Doorbell installation. It holds the device securely and ensures proper alignment.
Choose the Right Location
Your doorbell should be:
- About 5 feet (1.5 meters) above the ground
- Centered on the doorframe or wall
- Tilted slightly toward the walkway (about 15–30 degrees) for better motion detection
Avoid placing it directly under bright lights or in full sun, as this can cause glare or overheating.
Mark and Drill Holes
- Hold the mounting plate against the wall in your chosen spot.
- Use a pencil to mark the screw holes.
- Drill pilot holes if you’re mounting into brick, concrete, or hard wood.
- Secure the plate with the provided screws.
Tip: Use wall anchors if your wall is drywall or plaster and the screws don’t grip well.
Step 5: Connect the Wires (Wired Models Only)
If you’re installing the wired Google Doorbell, now’s the time to connect the wires.
How to Wire Your Google Doorbell
- Strip about 1/4 inch of insulation from the ends of the two wires (if not already done).
- Loosen the terminal screws on the back of the Google Doorbell or mounting plate.
- Insert one wire into each terminal. It doesn’t matter which wire goes where—Google Doorbell is non-polarized.
- Tighten the screws to secure the wires.
- Gently tug to ensure they’re snug.
Double-check that no bare wire is exposed outside the terminals to prevent short circuits.
Step 6: Attach the Google Doorbell
With the mounting plate in place and wires connected (if applicable), it’s time to snap on the doorbell.
Secure the Device
- Align the Google Doorbell with the mounting plate.
- Push it firmly until you hear a click—it should lock into place.
- Use the included security screw and screwdriver to secure the bottom of the device. This prevents theft.
For battery models, simply attach the doorbell to the plate—no wiring needed.
Step 7: Turn the Power Back On
If you turned off the breaker, now’s the time to restore power.
- Go back to your electrical panel.
- Flip the doorbell or main breaker back on.
- Wait 30–60 seconds for the doorbell to power up.
You should see a light ring on the front of the device. A solid white light means it’s ready to connect.
Step 8: Set Up the Google Doorbell in the App
The Google Home app is your command center for the doorbell. Here’s how to get it connected.
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.
Add Your Doorbell
- Tap the “+” icon in the top-left corner.
- Select “Set up device.”
- Choose “New device.”
- Follow the on-screen prompts to scan the QR code on the back of your doorbell or enter the setup code manually.
