Before you even think about drilling holes or touching wires, make sure your home can support the Nest Hello. This smart doorbell is designed to work with existing wired doorbell systems—not battery-powered ones. Here’s what you need to verify:
Existing Doorbell Wiring
Your home should have low-voltage doorbell wires running from the doorbell button to the chime inside. These are usually thin, color-coded wires (often white and red or white and yellow) tucked behind your current doorbell.
If you don’t have any wires at your door, the Nest Hello won’t work unless you run new wiring—which is a bigger project. In that case, consider the battery-powered Nest Doorbell (battery) instead.
Transformer Voltage
The Nest Hello requires a transformer that outputs between 16 and 24 volts AC (alternating current) and at least 500mA of power. Most modern homes have transformers in this range, but older homes might not.
To check:
– Locate your doorbell transformer. It’s usually near your electrical panel, in the basement, attic, or garage.
– Look for a small metal box with wires connected to it and a label showing voltage (e.g., “16V” or “24V”).
– If you can’t find it or the voltage is below 16V, you may need to upgrade your transformer. Call an electrician if you’re unsure.
Mechanical vs. Digital Chime
The Nest Hello works with both mechanical (ding-dong) and digital (electronic sound) chimes. However, if you have a mechanical chime, you may need the Nest Chime Connector (sold separately) to prevent “chime buzzing” or failure to ring.
The Chime Connector bypasses the chime’s internal mechanism and ensures reliable ringing. Google recommends using it if your chime makes a loud, clanging sound when pressed.
Wi-Fi Requirements
Your Nest Hello needs a strong 2.4 GHz Wi-Fi signal at the door. 5 GHz networks aren’t supported. Use a Wi-Fi analyzer app (like NetSpot or Wi-Fi Analyzer) to check signal strength. If it’s weak, consider a Wi-Fi extender or mesh system.
Step 2: Gather Your Tools and Parts
You don’t need a full toolbox, but having the right gear makes the job smoother. Here’s what to have on hand:
Tools You’ll Need
- Phillips-head screwdriver
- Drill with 3/16” drill bit (optional, for new mounting holes)
- Level (to keep the doorbell straight)
- Smartphone with the Google Home app installed
- Electrical tape (for wire safety)
- Wire strippers (if you need to trim or strip wires)
Parts Included with Nest Hello
When you open the box, you should find:
– Nest Hello doorbell
– Two mounting screws
– Two wire extenders (short wires with connectors)
– Two screw caps (for a clean look)
– Two optional security screws (to prevent tampering)
– Installation guide and quick start card
If anything’s missing, contact Google Support before proceeding.
Step 3: Turn Off the Power
Safety first! Even though doorbell wires carry low voltage, they’re still connected to your home’s electrical system. Turning off the power prevents shocks, short circuits, or damage to your doorbell.
Locate Your Circuit Breaker
Go to your main electrical panel and find the breaker labeled “Doorbell,” “Chime,” or something similar. If there isn’t one, look for breakers that control outlets near the doorbell or chime.
Turn Off the Breaker
Switch the breaker to the “OFF” position. To be extra safe, test the doorbell button—if it doesn’t ring, the power is off.
Use a Non-Contact Voltage Tester (Optional but Recommended)
If you have one, hold the tester near the wires at the doorbell. If it beeps or lights up, power is still on—double-check your breaker.
Step 4: Remove Your Old Doorbell
Now it’s time to take off the old doorbell. This step varies slightly depending on your setup, but here’s the general process.
Unscrew the Old Doorbell
Use your screwdriver to remove the screws holding the old doorbell to the wall. Gently pull it away from the wall—don’t yank it, as the wires are still attached.
Disconnect the Wires
You’ll see two wires (usually white and another color). Loosen the terminal screws and pull the wires free. If the wires are short or frayed, use wire strippers to trim and expose fresh copper (about 1/4 inch).
Cap the Wires (Temporarily)
Twist wire nuts or electrical tape over the exposed ends to prevent them from touching each other or the wall. This keeps things safe while you work.
Remove the Old Mounting Plate (If Needed)
If your old doorbell used a mounting plate, unscrew it. The Nest Hello comes with its own plate, so you’ll replace it.
Step 5: Install the Nest Hello Mounting Plate
The Nest Hello uses a special mounting plate that holds the doorbell securely and hides the wires.
Position the Plate
Hold the Nest mounting plate against the wall where you want the doorbell. Use a level to make sure it’s straight. The ideal height is about 48 inches from the ground—eye level for most visitors.
Mark the Screw Holes
Use a pencil to mark where the screw holes will go. If you’re replacing an old doorbell, the holes may already be there. If not, you’ll need to drill new ones.
Drill Pilot Holes (If Needed)
If your wall is brick, concrete, or hard material, drill pilot holes with a 3/16” bit. This prevents cracking and makes screwing easier.
Attach the Plate
Line up the plate with your marks and screw it into place using the included screws. Don’t overtighten—just snug enough to hold firmly.
Route the Wires Through the Plate
Feed the two doorbell wires through the center hole in the mounting plate. Leave about 2–3 inches of wire sticking out.
Step 6: Connect the Wires to the Nest Hello
Now it’s time to wire up your new doorbell. The Nest Hello uses the same two-wire system as traditional doorbells.
Prepare the Wires
Strip about 1/4 inch of insulation from each wire if you haven’t already. Twist the copper strands to keep them neat.
Attach the Wire Extenders (Recommended)
Google includes two short wire extenders with connectors. These make wiring easier and reduce strain on the doorbell.
– Plug one end of a wire extender into the Nest Hello’s terminal block (labeled “Front” and “Trans”).
– Connect the doorbell wire to the other end of the extender.
– Repeat for the second wire.
If you skip the extenders, you can connect the wires directly to the Nest Hello’s terminals. Just loosen the screws, insert the wires, and tighten.
Secure the Connections
Make sure the wires are firmly in place and not loose. Loose connections can cause power issues or intermittent operation.
Step 7: Attach the Nest Hello to the Mounting Plate
With the wires connected, it’s time to mount the doorbell.
Align the Doorbell
Hold the Nest Hello against the mounting plate. The bottom should snap into place, and the top will have a small tab that fits into the plate.
Secure with Screws
Use the included security screws (or regular screws) to fasten the top of the doorbell to the plate. This prevents tampering and keeps it firmly in place.
Snap on the Screw Caps
Place the decorative screw caps over the screws for a clean, finished look.
Step 8: Turn the Power Back On
Now that everything is connected, restore power.
Flip the Breaker
Go back to your electrical panel and turn the doorbell breaker back to “ON.”
Test the Doorbell
Press the button on the Nest Hello. You should hear a chime inside (if your chime is compatible) and see a light ring on the doorbell.
If nothing happens, double-check your wiring and breaker. If the chime buzzes or doesn’t ring, you may need the Nest Chime Connector.
Step 9: Set Up the Nest Hello with the Google Home App
The final step is connecting your doorbell to your phone and Wi-Fi. This is where the magic happens.
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).
Sign In or Create a Google Account
Use your existing Google account or create a new one. This account will manage your Nest devices.
Start the Setup Process
Open the app and tap the “+” icon, then select “Set up device” > “New device.”
Scan the QR Code
The app will ask you to scan the QR code on the back of your Nest Hello. Hold your phone steady until it recognizes the code.
Connect to Wi-Fi
Choose your 2.4 GHz Wi-Fi network and enter the password. The doorbell will connect and download any necessary updates.
Configure Settings
The app will guide you through:
– Naming your doorbell (e.g., “Front Door”)
– Setting up motion zones (so you only get alerts for important areas)
– Enabling notifications (push, email, or both)
– Adjusting video quality and night vision
Test the Features
Walk in front of the doorbell to test motion detection. Press the button to test two-way audio. Make sure you can see and hear clearly.
Step 10: Final Tips and Maintenance
Your Nest Hello is now installed and working—great job! Here are a few tips to keep it running smoothly:
Keep It Clean
Wipe the lens and body with a soft, dry cloth every few weeks to prevent dirt and grime from affecting video quality.
Check Wi-Fi Signal Regularly
If you notice lag or disconnections, check your Wi-Fi signal at the door. Move your router or add an extender if needed.
Enable Automatic Updates
In the Google Home app, go to your doorbell settings and turn on “Automatic updates.” This ensures you get the latest security patches and features.
Use Activity Zones
Set up activity zones to focus on your walkway or driveway. This reduces false alerts from passing cars or animals.
