Step 1: Check Compatibility and Power Requirements
Not all doorbell systems work with the wired Nest Doorbell. Before you start, make sure your existing setup is compatible.
Check Your Transformer
The Nest Doorbell requires a transformer that outputs 8–24 volts AC and provides at least 10 volt-amperes (VA) of power. Most older doorbells use 16V transformers, which work perfectly.
To check:
1. Locate your doorbell transformer. It’s usually near your doorbell chime inside the house, often in a basement, closet, or garage.
2. Look for a label that shows voltage (V) and VA rating.
3. If it says 16V and 10VA or higher, you’re good to go.
If your transformer is below 8V or under 10VA, the doorbell may not work reliably. You may need to upgrade it—consider hiring an electrician if you’re unsure.
Test Existing Wires
Use a voltage tester to check if your current doorbell wires are live and delivering enough power.
1. Turn off power at the breaker (we’ll cover this next).
2. Remove the old doorbell.
3. Touch the tester probes to the two doorbell wires.
4. If the tester shows 8–24V AC, your wiring is compatible.
If there’s no voltage, the wires may be disconnected or the transformer faulty.
Step 2: Turn Off Power at the Breaker
Safety first! Working with electrical wires can be dangerous if power is still on.
Locate Your Electrical Panel
Find your home’s main electrical breaker box. It’s usually in a basement, garage, or utility closet.
Turn Off the Correct Circuit
1. Look for a breaker labeled “doorbell,” “chime,” or “low voltage.” If unsure, turn off the main breaker to be safe.
2. Flip the switch to the “OFF” position.
3. Use your voltage tester on the doorbell wires again to confirm no power is flowing.
Pro Tip: Place a note on the breaker box saying “Do not turn on – working on doorbell” to prevent accidents.
Step 3: Remove Your Old Doorbell
Now that power is off, it’s time to remove the existing doorbell.
Unscrew the Old Unit
1. Use a screwdriver to remove the screws holding the old doorbell to the wall.
2. Gently pull the doorbell away from the wall.
3. You’ll see two wires connected to the back.
Disconnect the Wires
1. Loosen the terminal screws or release the wire connectors.
2. Carefully pull the wires free.
3. Important: Don’t let the wires fall back into the wall. Use electrical tape to tape them to the wall or hold them with a clip.
Remove the Old Mounting Plate (if applicable)
If your old doorbell had a backplate, unscrew and remove it. You’ll install the new Nest mounting plate in the next step.
Step 4: Prepare the Wires and Install the Mounting Plate
The Nest Doorbell comes with a wire harness that makes connecting easier.
Strip the Wire Ends (if needed)
If the wire ends are frayed or too short:
1. Use wire strippers to remove about 1/4 inch of insulation.
2. Twist the exposed copper to keep strands together.
Connect the Wire Harness
1. Take the included wire harness (a small plastic connector with two terminals).
2. Insert one doorbell wire into each terminal.
3. Tighten the screws to secure the wires.
4. The harness has two wires coming out—red and white. These will connect to the Nest Doorbell.
Mount the Backplate
1. Hold the Nest mounting plate against the wall where you want the doorbell.
2. Use a level to make sure it’s straight.
3. Mark the screw holes with a pencil.
4. If drilling new holes, use a drill bit slightly smaller than the wall anchors.
5. Insert wall anchors if needed (for drywall or brick).
6. Screw the mounting plate into place using the provided screws.
Tip: If your wall is angled (like on a corner), use the included wedge kit. Attach the wedge to the backplate before mounting for a better camera angle.
Step 5: Connect the Nest Doorbell
Now it’s time to attach the doorbell to the wires and mount it.
Attach the Doorbell to the Harness
1. Take the Nest Doorbell and locate the two connection points on the back.
2. Connect the red wire from the harness to one terminal and the white wire to the other.
3. The terminals are labeled “Front” and “Trans,” but polarity doesn’t matter—either wire can go in either slot.
Secure the Doorbell to the Mounting Plate
1. Align the doorbell with the mounting plate.
2. Slide it down until it clicks into place.
3. Use the included security screw and tool to lock it in. This prevents theft.
Note: Don’t tighten the security screw too much—just snug enough to hold it securely.
Step 6: Turn Power Back On and Test
Before celebrating, let’s make sure everything works.
Restore Power
1. Go back to the breaker box.
2. Turn the doorbell circuit back on.
3. Wait about 30 seconds for the doorbell to power up.
Check for Lights
The Nest Doorbell has a status light:
– Solid white: Power is on, but not connected to Wi-Fi.
– Blinking blue: Ready for setup.
– Solid blue: Connected and working.
If the light doesn’t turn on, double-check your wiring and power.
Step 7: Set Up the Nest Doorbell Using the Google Home App
Now for the fun part—connecting your doorbell to your phone.
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).
Add Your Doorbell
1. Open the app and sign in with your Google account.
2. Tap the “+” icon in the top left.
3. Select “Set up device.”
4. Choose “New device.”
5. The app will search for nearby devices. Your Nest Doorbell should appear.
6. Tap it to begin setup.
