Pro tip: Charge the wall battery fully before installation. It typically takes about 4–6 hours to reach full capacity using the included USB cable. A fully charged battery can power your Nest Hello for up to several months, depending on usage.
Step 1: Turn Off Power and Prepare the Area
Safety is the most important part of any electrical installation. Even though the Nest Hello uses a battery, it can still connect to existing doorbell wiring—and that wiring carries electricity.
Turn Off the Power
Locate your home’s main electrical panel (breaker box). Find the circuit that controls your doorbell—this is often labeled “doorbell,” “chime,” or “front door.” If you’re unsure, turn off the main power or test the doorbell button to see if it still rings.
Once you’ve identified the correct breaker, switch it off. Use a voltage tester on the doorbell wires to confirm there’s no current flowing. This step prevents accidental shocks and protects your Nest Hello from power surges.
Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, gently remove the old unit. Unscrew the mounting plate and disconnect the wires. Don’t cut the wires—just loosen the terminals and pull them free. Label the wires (e.g., “front” and “transformer”) with tape so you know how to reconnect them later.
Clean the wall surface where the old doorbell was mounted. Remove any debris, dust, or old adhesive. A clean surface ensures the new wall plate adheres properly.
Check Wi-Fi Signal Strength
The Nest Hello requires a strong Wi-Fi connection to function properly. Stand at your front door with your smartphone and check the signal strength. If it’s weak, consider installing a Wi-Fi extender or mesh network to boost coverage.
Tip: The Nest Hello works best on 2.4 GHz networks. If your router broadcasts both 2.4 GHz and 5 GHz, make sure your phone connects to the 2.4 GHz band during setup.
Step 2: Install the Wall Plate and Mounting Bracket
The wall plate is the foundation of your Nest Hello installation. It holds the doorbell securely and hides the wiring (if used). Proper alignment ensures the camera has a clear view of your doorstep.
Position the Wall Plate
Hold the wall plate against the wall at a height of about 48 inches (4 feet) from the ground—this is the recommended height for optimal motion detection and video quality. Use a level to make sure it’s straight.
Mark the screw holes with a pencil. If you’re mounting on brick, stucco, or concrete, you’ll need to drill pilot holes and use wall anchors. For wood or drywall, standard screws usually suffice.
Drill and Secure the Plate
Using the appropriate drill bit, create holes where you marked. Insert wall anchors if needed, then screw the wall plate into place. Make sure it’s tight and doesn’t wobble.
If you’re using existing wiring, feed the wires through the center hole of the wall plate. Leave about 3–4 inches of wire exposed for connection.
Optional: Use the Corner Mount
If your door is near a corner or you want a wider viewing angle, Nest offers a corner mount kit. This angled bracket allows the doorbell to face outward, capturing more of your porch or walkway.
Install the corner mount the same way as the standard plate—drill, anchor, and screw. Then attach the wall plate to the corner mount using the provided screws.
Step 3: Connect the Wiring (If Applicable)
Even though you’re using a wall battery, connecting the existing doorbell wiring can help keep the battery charged and provide backup power. This is called “trickle charging” and extends battery life.
Strip the Wire Ends
If your wires have insulation covering the ends, use wire strippers to expose about 1/4 inch of copper. Be careful not to cut the wire itself.
Attach Wires to the Nest Hello
The Nest Hello has two terminals labeled “Front” and “Transformer.” Connect the wires from your doorbell circuit to these terminals. It doesn’t matter which wire goes where—the Nest Hello is designed to work either way.
Tighten the terminal screws securely. Loose connections can cause power issues or prevent the doorbell from working.
Use Wire Connectors for Extra Security
For added safety, especially in older homes, use wire nuts or electrical tape to cover the connections. This prevents accidental contact and reduces the risk of short circuits.
Note: If your home doesn’t have existing wiring, skip this step. The wall battery will power the doorbell independently.
Step 4: Attach the Nest Hello to the Wall Plate
Now it’s time to mount the actual doorbell unit. This step is quick but requires careful alignment.
Slide the Doorbell into Place
Hold the Nest Hello with the camera facing outward. Align the bottom of the unit with the wall plate and gently slide it down until it clicks into place. You should hear a secure snap.
Give the doorbell a light tug to ensure it’s locked in. If it feels loose, double-check the alignment and press down firmly.
Secure with the Security Screw
To prevent theft or tampering, use the small security screw included in the package. Insert it into the hole at the bottom of the doorbell and tighten with a screwdriver.
This screw prevents someone from easily sliding the doorbell off the wall plate. Keep the screwdriver handy—you’ll need it to remove the doorbell for battery charging or maintenance.
Step 5: Insert and Charge the Wall Battery
The wall battery is the heart of your wire-free setup. Proper installation and charging ensure long-term performance.
Locate the Battery Compartment
On the back of the Nest Hello, you’ll find a small compartment labeled “Battery.” Use a screwdriver to remove the cover.
Insert the Battery
Place the rechargeable wall battery into the compartment with the contacts aligned. Push it in until it clicks. Replace the cover and tighten the screw.
Charge the Battery (If Not Already Done)
If you haven’t charged the battery yet, now is the time. Use the included USB cable to connect the battery to a power source. A full charge takes about 4–6 hours.
Tip: Charge the battery indoors at room temperature. Extreme heat or cold can affect charging efficiency.
Step 6: Download the Google Home App and Set Up the Doorbell
The Nest Hello works seamlessly with the Google Home app, which guides you through setup, customization, and monitoring.
Download and Open the App
On your smartphone or tablet, download the Google Home app from the App Store (iOS) or Google Play (Android). Create a Google account if you don’t already have one.
Scan the QR Code
Open the app and tap “+” to add a new device. Select “Set up device” and then “New device.” Point your camera at the QR code on the Nest Hello’s packaging or inside the battery compartment.
The app will detect the doorbell and begin the setup process.
Connect to Wi-Fi
Follow the on-screen prompts to connect the Nest Hello to your home Wi-Fi network. Enter your network name (SSID) and password when prompted.
The doorbell will take a minute or two to connect. Once connected, you’ll see a confirmation message in the app.
Customize Settings
After setup, you can customize features like:
- Motion detection zones
- Person alerts
- Doorbell notifications
