Pro Tip: If you’re unsure about your home’s wiring or electrical setup, consider consulting an electrician. It’s better to be safe than sorry.
Step 1: Turn Off the Power
This is the most important step—always turn off the power before working with electrical wiring.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “doorbell,” “chime,” or something similar. If it’s not labeled, you may need to test breakers by turning them off one at a time and checking if your existing doorbell stops working.
Turn Off the Correct Breaker
Switch the breaker to the “OFF” position. Use a non-contact voltage tester near the doorbell wires to confirm there’s no electricity flowing. If the tester beeps or lights up, the power is still on—double-check your breaker.
Safety Note: Never assume the power is off. Always test with a voltage tester.
Test the Doorbell
Press your existing doorbell button. If it doesn’t ring, the power is likely off. If it still rings, go back to the breaker panel and try another breaker.
Once you’re sure the power is off, you’re ready to remove the old doorbell.
Step 2: Remove the Old Doorbell
Now that the power is off, it’s time to take down your old doorbell.
Unscrew the Faceplate
Use your Phillips screwdriver to remove the screws holding the old doorbell button in place. Gently pull the faceplate away from the wall. You should see two wires connected to the back.
Disconnect the Wires
Loosen the terminal screws or release the wire clips (depending on your model) and carefully pull the wires free. Don’t let them fall back into the wall—use a piece of tape to hold them in place.
Tip: Take a photo of the wiring before disconnecting. This can help if you need to reference it later.
Inspect the Wires
Check the exposed ends of the wires. Are they frayed, corroded, or too short? If so, you may need to strip back a bit more insulation (about 1/4 inch) using wire strippers. Clean any corrosion with sandpaper.
If the wires are damaged or too short, you may need to extend them or consult an electrician.
Remove the Old Mounting Plate
Unscrew and remove the old mounting bracket. Clean the area if there’s old caulk or paint.
Now your wall is ready for the new Nest Doorbell.
Step 3: Check Your Transformer and Chime Compatibility
Before installing the Nest Doorbell, you need to make sure your home’s electrical system can support it.
What Is a Doorbell Transformer?
The transformer converts your home’s standard 120V AC power down to a lower voltage (usually 16–24V AC) that powers the doorbell. The Google Nest Doorbell (wired) requires a transformer that outputs 16–24V AC with at least 500mA of current.
How to Check Your Transformer
Most transformers are located near the chime unit inside your home (often in the basement or closet). Open the chime cover and look for a small black or gray box with wires connected to it. It should have labels indicating voltage and amperage.
If your transformer is labeled 16V or 24V and 500mA or higher, you’re good to go. If it’s lower (like 8V or 10V), you’ll need to upgrade it.
Warning: Using an underpowered transformer can cause the Nest Doorbell to malfunction, overheat, or fail to charge (if using a battery model). Since this is the wired version, consistent power is essential.
Test the Chime
The Nest Doorbell works with most mechanical and digital chimes. However, some very old or incompatible chimes may not work properly.
To test, temporarily reconnect your old doorbell and press the button. If it chimes clearly, your system is likely compatible.
If you have a digital chime or a smart chime (like Nest Chime or Ring Chime), the Nest Doorbell should work fine.
Note: The Nest Doorbell (wired) does not include a chime—it relies on your existing chime unit inside the house.
Step 4: Install the Nest Doorbell Mounting Plate
Now it’s time to mount the Nest Doorbell’s base plate.
Position the Mounting Plate
Hold the Nest mounting plate (the flat metal piece that comes with the doorbell) against the wall where you want to install the doorbell. Make sure it’s level and at a comfortable height (usually about 48 inches from the ground).
Use a pencil to mark the screw holes.
Drill Pilot Holes (If Needed)
If you’re drilling into wood, you can screw directly into the wall. For brick, concrete, or hollow walls, drill pilot holes and insert wall anchors.
Tip: Use a drill bit slightly smaller than your anchors for a snug fit.
Secure the Mounting Plate
Line up the plate with your marks and screw it into place using the included screws. Make sure it’s tight and level.
Use the Wedge or Trim Plate (Optional)
If your doorbell isn’t aligned properly with the door or you want a better viewing angle, use the included wedge or trim plate.
– The wedge tilts the doorbell slightly to the left or right.
– The trim plate covers gaps if your old doorbell was larger.
Attach the wedge or trim plate to the mounting plate before securing it to the wall.
Step 5: Connect the Wires to the Nest Doorbell
This is the crucial step—connecting the wires correctly.
Identify the Wires
You should have two wires: typically labeled “Front” and “Trans” (or just two wires with no labels). It doesn’t matter which wire goes where—the Nest Doorbell is not polarity-sensitive.
Strip the Wire Ends (If Needed)
If the wire ends are too short or damaged, use wire strippers to expose about 1/4 inch of copper.
Insert Wires into the Base Plate
On the back of the Nest mounting plate, you’ll see two small terminals with push-in slots.
– Push one wire into the left slot.
– Push the other wire into the right slot.
Make sure the wires go in fully and aren’t touching each other.
Important: Don’t wrap the wires around screws—this model uses push-in connectors.
Secure the Wires
Once both wires are inserted, gently tug to make sure they’re secure. If a wire pulls out, reinsert it.
Step 6: Attach the Nest Doorbell to the Mounting Plate
Now it’s time to snap the doorbell onto the plate.
Align the Doorbell
Hold the Nest Doorbell so the camera lens is facing forward and the bottom tab aligns with the slot on the mounting plate.
Snap It Into Place
Gently press the doorbell onto the plate until you hear a click. It should lock securely.
Check the Fit
Make sure the doorbell is level and doesn’t wobble. If it’s loose, double-check the mounting plate and wire connections.
Step 7: Turn the Power Back On
Now that everything is connected, it’s time to restore power.
Go Back to the Breaker Panel
Switch the breaker back to the “ON” position.
Wait a Moment
Give the system 30–60 seconds to power up. The Nest Doorbell should light up with a green or white LED.
If the light doesn’t come on, double-check your wiring and transformer.
Step 8: Set Up the Nest Doorbell in the Google Home App
The final step is connecting your doorbell to your Wi-Fi and configuring it in the app.
Download the Google Home App
If you don’t already have it, download the Google Home app from the App Store (iOS) or Google Play (Android).
Open the App and Sign In
Sign in with your Google account. If you don’t have one, create it—it’s free.
Tap the “+” Icon
In the app, tap the “+” (plus) icon in the top-left corner, then select “Set up device”.
Choose “New Device”
Follow the prompts to add a new device. The app will search for nearby Nest devices.
Scan the QR Code
When prompted, point your phone’s camera at the QR code on the back of the Nest Doorbell (or on the packaging). The app will recognize the device.
Connect to Wi-Fi
Select your home Wi-Fi network and enter the password. The doorbell will connect to the internet.
Note: The Nest Doorbell requires a 2.4 GHz Wi-Fi network. It does not support 5 GHz-only networks.
Name Your Doorbell
Give your doorbell a name, like “Front Door” or “Main Entrance.”
Set Up Motion and Ring Alerts
Choose who gets notifications (you, family members, etc.) and customize alert settings.
Test the Doorbell
Press the button on the doorbell. You should hear the chime inside your home, and a notification should appear on your phone.
Open the app and tap the doorbell to view the live feed. Test two-way audio by speaking and listening.
