Why Choose a Wired Nest Doorbell?
Before diving into the installation, it’s important to understand why the wired Nest Doorbell is a great choice. Unlike battery-powered doorbells that require frequent recharging, the wired model draws power directly from your home’s doorbell circuit. This means you’ll never have to worry about dead batteries or interrupted service.
The wired Nest Doorbell also supports advanced features like 24/7 video recording (with a Nest Aware subscription), person detection, and package alerts. It connects to your home Wi-Fi network, allowing you to view live footage, talk to visitors, and receive notifications on your phone, tablet, or smart display.
Additionally, the wired version is more secure against tampering. Since it’s physically connected to your home’s wiring, it’s harder for someone to remove or disable it compared to a battery-powered model.
What You’ll Need Before You Begin
Before starting the installation, gather all the necessary tools and materials. Having everything ready will make the process smoother and safer.
Tools and Materials Checklist
- Nest Doorbell (wired version)
- Existing doorbell wiring (low-voltage, typically 16–24V AC)
- Screwdriver (Phillips and flathead)
- Voltage tester (non-contact or multimeter)
- Wire strippers
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Level
- Pencil or marker
- Electrical tape
- Optional: Wire nuts or terminal connectors
- Optional: Smart chime (if replacing a mechanical chime)
Most of these items are likely already in your toolbox. The Nest Doorbell comes with a mounting bracket, screws, and an anti-theft screw, so you won’t need to purchase those separately.
Step 1: Check Compatibility
Not all doorbell systems are compatible with the Nest Doorbell. Before you begin, verify that your existing setup meets the requirements.
Check Your Doorbell Transformer
The Nest Doorbell requires a transformer that outputs between 16V and 24V AC (alternating current) and at least 8VA (volt-amperes). Most older doorbells use 16V transformers, which are compatible.
To check your transformer:
- Locate your doorbell transformer. It’s usually found in the basement, attic, garage, or near your electrical panel.
- Look for a label that lists the voltage and VA rating. If it says 16V or 24V and at least 8VA, you’re good to go.
- If the transformer is labeled 8V or 12V, it’s likely too weak. You may need to upgrade it.
Test the Existing Wiring
Use a non-contact voltage tester or multimeter to confirm that power is reaching your current doorbell.
- Remove the old doorbell button.
- Touch the voltage tester to the two wires. If it beeps or lights up, power is present.
- If no power is detected, check the transformer or circuit breaker.
If your wiring is damaged or frayed, repair or replace it before installing the Nest Doorbell.
Check Your Chime
The Nest Doorbell works with both mechanical (ding-dong) and digital chimes. However, some older mechanical chimes may not work properly with smart doorbells.
If your chime is very old or makes a buzzing sound when the button is pressed, consider replacing it with a Nest-compatible smart chime or using the doorbell’s built-in speaker (if available).
Step 2: Turn Off the Power
Safety is paramount when working with electrical wiring. Always turn off the power before disconnecting or handling wires.
Locate the Circuit Breaker
Your doorbell is connected to a low-voltage circuit, but it’s still powered by your home’s electrical system. Find the breaker that controls the doorbell transformer.
- Go to your main electrical panel.
- Look for a breaker labeled “doorbell,” “chime,” or “transformer.” If there isn’t one, you may need to test breakers by turning them off one at a time.
- Turn off the breaker and use a voltage tester to confirm the power is off at the doorbell wires.
Label the Wires
Once the power is off, remove the old doorbell button and carefully note which wire connects to which terminal. Use tape or a marker to label them (e.g., “Front Door,” “Transformer”). This will help you reconnect them correctly later.
Step 3: Remove the Old Doorbell
Now that the power is off and the wires are labeled, it’s time to remove the old doorbell.
Unscrew the Old Button
Use a screwdriver to remove the screws holding the old doorbell button to the wall. Gently pull the button away from the wall to expose the wires.
Disconnect the Wires
Loosen the terminal screws and carefully remove the wires. If the wires are short or damaged, you may need to strip the ends to expose fresh copper. Use wire strippers to remove about 1/4 inch of insulation.
Cap the Wires (Temporarily)
To prevent the wires from touching each other or the wall, twist wire nuts over the exposed ends or wrap them with electrical tape. This will keep them safe while you prepare the new doorbell.
Step 4: Install the Mounting Bracket
The Nest Doorbell comes with a mounting bracket that attaches to the wall. Proper alignment is key to a clean, secure installation.
Position the Bracket
Hold the mounting bracket against the wall where you want to install the doorbell. Use a level to ensure it’s straight.
Mark the Screw Holes
Use a pencil to mark the locations of the screw holes. If you’re mounting on wood or siding, you can screw directly into the surface. For brick, stucco, or concrete, you’ll need to drill pilot holes and use wall anchors.
Drill and Secure the Bracket
- Drill pilot holes at the marked locations.
- Insert wall anchors if needed.
- Align the bracket with the holes and secure it with the provided screws.
Make sure the bracket is firmly attached and level. A loose bracket can cause the doorbell to tilt or fall off.
Step 5: Connect the Wires to the Nest Doorbell
Now it’s time to connect your home’s wiring to the Nest Doorbell.
Prepare the Wires
Remove the wire nuts or tape from the two doorbell wires. Strip about 1/4 inch of insulation from each end if needed.
Attach the Wires to the Doorbell
The Nest Doorbell has two terminal screws labeled “Front” and “Trans.” It doesn’t matter which wire goes where—both connections are interchangeable.
- Loosen the terminal screws on the back of the doorbell.
- Insert one wire into each terminal and tighten the screws securely.
- Give the wires a gentle tug to ensure they’re held firmly.
Tuck the Wires Neatly
Carefully push the excess wire back into the wall cavity to avoid pinching or damaging it when you attach the doorbell.
Step 6: Attach the Nest Doorbell to the Bracket
With the wires connected, it’s time to mount the doorbell.
Align and Secure
Hold the Nest Doorbell against the mounting bracket and slide it down until it clicks into place. The bracket has a locking mechanism that holds the doorbell securely.
Install the Anti-Theft Screw
Use the included anti-theft screw and a small screwdriver to secure the bottom of the doorbell. This prevents someone from easily removing it.
Step 7: Restore Power and Test
Now that the doorbell is installed, it’s time to turn the power back on and test the system.
Turn On the Breaker
Go back to your electrical panel and turn the doorbell breaker back on.
Check for Power
Wait a few seconds, then press the doorbell button. You should hear a chime (if connected) and see the doorbell’s light ring illuminate.
If nothing happens, double-check your wiring and breaker. Use a voltage tester to confirm power is reaching the doorbell.
Step 8: Set Up the Nest Doorbell via the Google Home App
The final step is configuring your Nest Doorbell using the Google Home app.
Download the App
If you haven’t already, download the Google Home app on your smartphone or tablet (available for iOS and Android).
Add the Doorbell
- Open the app and tap the “+” icon to add a new device.
- Select “Set up device” and choose “New device.”
- Follow the on-screen instructions to scan the QR code on the back of your Nest Doorbell.
