- Wi-Fi network (2.4 GHz or 5 GHz)
- Charger cable (USB-C, included)
Check Your Existing Doorbell System
The Nest Doorbell Battery Wired is designed to work with most standard doorbell systems, but it’s important to verify compatibility.
First, check your doorbell transformer. It should output between 16 and 24 volts AC. You can usually find this info on the transformer itself, which is typically located in your basement, garage, or utility closet. If you’re unsure, use a multimeter to test the voltage at the doorbell terminals.
Next, confirm that your existing chime is mechanical (not digital). The Nest Doorbell works best with traditional mechanical chimes. If you have a digital chime, you may need a Nest Chime Connector (sold separately) to make it work.
Also, make sure there’s enough space on your doorframe or wall. The Nest Doorbell is about 5 inches tall and 2.5 inches wide, so you’ll need a clear area with no obstructions.
Charge the Battery
Even though this model is wired, it still uses a rechargeable battery. Google recommends charging the battery fully before installation. This ensures the doorbell has enough power to complete the setup process and connect to your Wi-Fi network.
To charge:
- Remove the battery from the back of the doorbell (press the release button).
- Connect the USB-C cable to the battery and plug it into a power source.
- Charge for at least 4–6 hours or until the light turns green.
- Reinsert the battery into the doorbell.
Pro tip: Charge the battery indoors while you prep the installation. That way, it’s ready to go when you’re done.
Step 1: Turn Off the Power
Safety first! Even though doorbell wires carry low voltage, it’s still important to turn off the power before working on them.
Locate Your Doorbell Transformer
The transformer steps down your home’s 120V electricity to the 16–24V needed for the doorbell. It’s usually found in one of these places:
- Basement near the furnace or water heater
- Garage ceiling or wall
- Utility closet
- Attic (less common)
Once you find it, look for a circuit breaker labeled “doorbell,” “chime,” or “transformer.” If there isn’t a dedicated breaker, you may need to turn off the main breaker or locate the correct one by testing.
Turn Off the Breaker
Switch the breaker to the “off” position. To be extra safe, test the doorbell button to make sure the chime doesn’t ring. If it does, the power is still on—double-check your breaker.
Never skip this step. Even low voltage can cause a shock or damage your new doorbell.
Step 2: Remove Your Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell.
Unscrew the Old Unit
Use your screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away from the wall. You’ll see two wires connected to the back—these are your doorbell wires.
Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. Don’t let them fall back into the wall. You can tape them to the wall or hold them with a piece of tape to keep them accessible.
If the wires are short or frayed, you may need to strip the ends slightly to expose fresh copper. Use wire strippers or carefully trim with scissors.
Pro tip: Take a photo of the wiring before disconnecting. This can help if you need to troubleshoot later.
Step 3: Install the Mounting Plate
The mounting plate is what holds your Nest Doorbell securely to the wall. It also helps align the wires and provides a clean finish.
Choose the Right Plate
The Nest Doorbell comes with a flat mounting plate and an optional angled plate. Use the angled plate if your doorbell is installed at an angle (like on a corner or slanted wall) to improve the viewing angle.
Position the Plate
Hold the mounting plate against the wall where you want to install the doorbell. Use a level to make sure it’s straight. The ideal height is about 48 inches from the ground—eye level for most visitors.
Mark the screw holes with a pencil.
Drill Pilot Holes (If Needed)
If you’re mounting into wood or drywall, you can usually screw directly into the wall. But for brick, concrete, or stucco, drill pilot holes first.
Use a 1/4-inch drill bit to create holes at the marked spots. Insert wall anchors if needed—these provide extra grip in hard surfaces.
Attach the Plate
Align the mounting plate with the holes and secure it with the provided screws. Make sure it’s tight and level.
Connect the Wires
Thread the doorbell wires through the center hole of the mounting plate. Then, connect them to the two terminals on the back of the plate. It doesn’t matter which wire goes where—Nest Doorbell is non-polarized.
Tighten the screws to secure the wires. Give them a gentle tug to make sure they’re snug.
Step 4: Attach the Nest Doorbell
Now it’s time to mount the actual doorbell.
Align the Doorbell
Hold the Nest Doorbell against the mounting plate. The bottom of the doorbell should snap into the plate’s hooks.
Secure with the Security Screw
Once the doorbell is in place, use the included security screw to lock it down. This prevents theft and ensures it stays firmly attached.
Use the small Allen wrench (included) to tighten the screw. Don’t over-tighten—just snug is fine.
Step 5: Turn the Power Back On
With the doorbell installed, it’s safe to restore power.
Go back to your breaker panel and turn the doorbell circuit back on. Wait a few seconds for the system to power up.
You should see the doorbell’s status light turn on. It may blink yellow or white as it initializes.
Step 6: Set Up the Nest Doorbell with the App
The final step is pairing your doorbell with the Google Home or Nest app. This is where the magic happens—connecting to Wi-Fi, setting up alerts, and customizing your experience.
Download the App
If you haven’t already, download the Google Home app (for newer Nest devices) or the Nest app (for older models) from the App Store or Google Play.
Sign in with your Google account.
Start the Setup Process
Open the app and tap the “+” icon to add a new device. Select “Video doorbell” and follow the on-screen prompts.
The app will ask you to scan the QR code on the back of your doorbell. Use your phone’s camera to scan it.
Connect to Wi-Fi
Choose your home Wi-Fi network and enter the password. The doorbell supports both 2.4 GHz and 5 GHz networks, but 2.4 GHz is recommended for better range.
Wait while the doorbell connects. This may take a minute or two.
Test the Doorbell
Once connected, the app will guide you through a quick test:
- Check the live video feed
- Test two-way audio (speak and listen)
- Trigger a motion alert by walking in front of the doorbell
If everything works, you’re all set!
Customize Settings
Now’s the time to personalize your doorbell:
- Set activity zones to focus on specific areas (like your walkway)
- Adjust motion sensitivity
- Enable package detection (if available in your region)
- Choose notification preferences (push alerts, email, etc.)
- Set up familiar face alerts (requires Nest Aware subscription)
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix the most common problems.
