Before you touch a single screw, make sure you have everything you need. Rushing into installation without the right tools can lead to frustration—or worse, damage to your doorbell or wiring.

Here’s a checklist of items you’ll need:

  • Nest Hello doorbell kit: Includes the doorbell, mounting plate, screwdriver, wire labels, and chime connector.
  • Screwdriver (Phillips head): For removing your old doorbell and securing the new one.
  • Drill and drill bits (optional): Only if you need to make new holes for mounting.
  • Voltage tester (recommended): To confirm power is off before working with wires.
  • Smartphone with the Nest app installed: Available for iOS and Android.
  • Wi-Fi network: Nest Hello requires a 2.4 GHz or 5 GHz Wi-Fi connection.
  • Ladder (if needed): For reaching high doorbell locations.

Pro tip: If you’re replacing an existing doorbell, you likely already have most of the wiring in place. That makes installation much easier. But if you’re installing from scratch, you may need to run wires—something best left to a professional electrician.

Step 1: Check Compatibility

Not every doorbell system works with the Nest Hello. To avoid problems during installation, you need to verify compatibility first.

Check Your Existing Doorbell Wiring

The Nest Hello requires a wired connection to function. It doesn’t run on batteries, so you must have low-voltage doorbell wires (typically 16–24 volts AC) running from your chime to the doorbell location.

To check:

  1. Remove your current doorbell from the wall.
  2. Look for two wires connected to the back.
  3. Use a multimeter or voltage tester to confirm the voltage is between 8V and 24V AC.

If you don’t have wires, or if the voltage is too low, the Nest Hello won’t work properly. In that case, you may need to install a transformer or consider a battery-powered alternative like the Nest Doorbell (battery).

Check Your Chime Type

The Nest Hello works with most mechanical and digital chimes. However, some older or specialty chimes (like those with solenoids or very low power) may not be compatible.

Google provides a chime compatibility checker on their support site. Enter your chime model to confirm. If your chime isn’t compatible, you can still use the Nest Hello—but you’ll need to install the included chime connector inside your chime box. We’ll cover that in Step 4.

Wi-Fi Requirements

The Nest Hello needs a stable Wi-Fi connection to send video and alerts. Make sure your router is within range (ideally within 30–50 feet) and supports either 2.4 GHz or 5 GHz bands.

Avoid using Wi-Fi extenders unless they’re high-quality and placed close to the doorbell. Weak signals can cause lag or dropped connections.

Step 2: Turn Off the Power

Safety first! Before you touch any wires, you must turn off the power to your doorbell.

Locate Your Circuit Breaker

Doorbell circuits are usually labeled “doorbell,” “chime,” or “front door.” If you can’t find it, turn off the main breaker to be safe.

Test the Power

Even after turning off the breaker, use a non-contact voltage tester to double-check that the wires are not live. Touch the tester to each wire—if it beeps or lights up, the power is still on. Go back and turn off the correct breaker.

Never skip this step. Working on live wires can cause shocks or damage your doorbell.

Step 3: Remove Your Old Doorbell

Now that the power is off, it’s time to remove your existing doorbell.

Unscrew the Old Doorbell

Use your Phillips screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the doorbell away from the wall so you can access the wires.

Label the Wires

You’ll see two wires—usually black and white, or red and white. Before disconnecting them, label them with the included wire labels (or tape and a pen). This ensures you connect them correctly to the Nest Hello.

Pro tip: Take a photo of the wiring before disconnecting. It’s a great reference if you get confused later.

Disconnect the Wires

Loosen the terminal screws on the old doorbell and remove the wires. Be careful not to let the wires fall back into the wall. You can use a small piece of tape to hold them in place.

Step 4: Install the Chime Connector (If Needed)

If your chime isn’t compatible with the Nest Hello, you’ll need to install the chime connector inside your chime box. This small device ensures the doorbell gets enough power and that your chime rings correctly.

Access Your Chime Box

The chime box is usually located in your basement, attic, or utility closet. Open the cover to see the wiring.

Connect the Chime Connector

The chime connector has three wires:

  • Two wires that connect to your existing chime terminals.
  • One wire that connects to the Nest Hello circuit.

Follow these steps:

  1. Disconnect the wires from your chime terminals.
  2. Connect those wires to the chime connector’s input terminals.
  3. Connect the chime connector’s output wire to the chime terminal.
  4. Secure the connector with the included screw or tape.

The Nest app will guide you through this process during setup. If you’re unsure, watch Google’s installation video or contact support.

Step 5: Mount the Nest Hello

Now it’s time to install the Nest Hello itself.

Attach the Mounting Plate

The Nest Hello comes with a mounting plate that screws into the wall. Hold it against the wall where you want the doorbell, making sure it’s level.

Use a pencil to mark the screw holes. If you’re reusing existing holes, great! If not, drill pilot holes and insert wall anchors if needed.

Secure the plate with the provided screws.

Connect the Wires

Take the two labeled wires from your wall and connect them to the back of the Nest Hello. It doesn’t matter which wire goes where—the Nest Hello is polarity-independent.

Push the wires into the terminals and tighten the screws. Make sure the connections are snug but don’t overtighten.

Snap the Doorbell into Place

Align the Nest Hello with the mounting plate and press it firmly until it clicks into place. Give it a gentle tug to make sure it’s secure.

Step 6: Adjust the Angle (Optional)

The Nest Hello has a fixed angle, but you might want to adjust it for better coverage—especially if your door is recessed or your walkway is off to the side.

Use the Wedge or Corner Kit

Google sells optional wedge and corner kits that let you tilt the doorbell up to 15 degrees. These are especially useful for:

  • Doors set back from the street.
  • Homes with side walkways.
  • Driveways that approach from an angle.

To install:

  1. Remove the Nest Hello from the mounting plate.
  2. Attach the wedge or corner bracket to the plate.
  3. Reconnect the doorbell.

This small adjustment can make a big difference in your video quality and motion detection.

Step 7: Turn the Power Back On

Once everything is connected, it’s time to restore power.

Go back to your circuit breaker and turn the doorbell circuit back on. Wait about 30 seconds for the Nest Hello to power up.

You should see a light ring on the front of the doorbell. It will flash yellow at first, then turn solid white when ready.

Step 8: Set Up the Nest App

The Nest app is your control center for the doorbell. It’s where you’ll connect to Wi-Fi, adjust settings, and receive alerts.

Download and Open the Nest App

If you haven’t already, download the Google Nest app from the App Store or Google Play. Sign in with your Google account.

Add a New Device

Tap the “+” icon and select “Set up a device.” Choose “Doorbell” and follow the on-screen instructions.

The app will ask you to scan the QR code on the back of the Nest Hello. Hold your phone close to the code until it scans.

Connect to Wi-Fi

Select your home Wi-Fi network and enter the password. The app will send the credentials to the doorbell.

Wait for the connection to complete. This may take a minute or two.

Test the Doorbell

Once connected, the app will guide you through a few tests:

  • Check the live video feed.
  • Test the two-way audio.
  • Verify motion detection.

Tap the doorbell button (or have someone else do it) to test the chime. You should hear it ring inside your home.

Step 9: Customize Your Settings

Now that your doorbell is working, it’s time to personalize it.

Set Up Motion Zones

You can define specific areas where you want to receive alerts. For example, you might want alerts when someone approaches your front door but ignore motion from the street.

In the app, go to “Settings” > “Motion sensing” and draw zones on the video preview.

Adjust Alert Frequency

Choose how often you want to be notified. Options include:

  • All motion.
  • Only people.
  • Frequent alerts (every event).
  • Less frequent (grouped alerts).

For most users, “Only people” and “Less frequent” strikes a good balance.

Enable Familiar Face Alerts (Optional)

If you have a Nest Aware subscription, you can enable Familiar Face Detection. The doorbell will recognize family members and regular visitors, sending personalized alerts.

Set Up Activity Zones

Create zones for your driveway, walkway, or porch. You’ll get alerts only when motion occurs in those areas.

Step 10: Test Everything

Before you call it a day, run a full test to make sure everything works.

  • Press the doorbell button—does the chime ring?
  • Open the live view in the app—is the video clear?
  • Speak through the app—can the visitor hear you?
  • Walk in front of the doorbell—do you get a motion alert?
  • Check night vision—cover the camera and see if it switches to infrared.

If anything isn’t working, go back to the troubleshooting section below.
