Step 1: Turn Off the Power

Safety comes first. Electricity and water don’t mix, and neither do live wires and fingers.

Locate Your Circuit Breaker

Go to your home’s main electrical panel. Look for a breaker labeled “doorbell,” “chime,” or “front door.” If you can’t find it, turn off the main breaker to be safe.

Test the Power

Use your non-contact voltage tester near the existing doorbell button. Press the button—if the tester beeps or lights up, power is still on. Double-check the breaker and turn it off again.

Pro Tip: Tape the breaker switch in the “off” position so no one accidentally turns it back on while you’re working.

Step 2: Remove the Old Doorbell

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

Unscrew the Faceplate

Use your screwdriver to remove the screws holding the old doorbell button in place. Gently pull the button away from the wall.

Label the Wires

You’ll see two wires connected to the back: one from the front door (usually marked “Front”) and one from the transformer (often labeled “Trans”). Use the wire labels included with your eufy kit to mark them. This prevents confusion later.

Disconnect the Wires

Loosen the terminal screws and carefully remove the wires. Keep them separated so they don’t touch each other or the wall.

Remove the Old Mounting Plate

Unscrew and remove the old mounting plate. If it’s glued or sealed, use a utility knife to cut through any caulk.

Step 3: Check Electrical Compatibility

Not all doorbells work with all homes. The eufy wired doorbell requires specific electrical conditions.

Check Voltage and Power

Your doorbell transformer should output between 8 and 24 volts AC and provide at least 10 volt-amperes (VA). Most modern homes meet this, but older homes may not.

To check:

Locate the transformer (usually near the furnace, basement, or attic).
Look for a label with voltage and VA ratings.
If it’s below 8V or under 10VA, you may need to upgrade the transformer.

Test the Wires

Use a multimeter to test the voltage between the two wires. Set it to AC voltage and touch the probes to each wire. You should see a reading between 8 and 24V.

Note: If you get no reading, the transformer may be faulty or the breaker may not be fully off.

Step 4: Prepare the Wires

Good connections are key to reliable performance.

Strip the Wire Ends

If the wire ends are frayed, corroded, or too short, strip about 1/4 inch of insulation using wire strippers. This exposes fresh copper for a solid connection.

Twist the Strands

If the wires are stranded, twist the copper strands tightly so they don’t splay out when inserted into the terminals.

Keep Wires Separate

Make sure the two wires don’t touch each other or any metal surface. Use electrical tape to insulate them if needed.

Step 5: Install the Mounting Bracket

The bracket holds the doorbell securely and aligns it properly.

Position the Bracket

Hold the eufy mounting bracket against the wall where the old doorbell was. Use a level to ensure it’s straight. Mark the screw holes with a pencil.

Drill Pilot Holes

Drill small pilot holes at the marked spots. This prevents the wall from cracking, especially if you’re drilling into brick or concrete.

Secure the Bracket

Insert wall anchors if needed, then screw the bracket into place. Make sure it’s tight and level.

Route the Wires

Feed the two labeled wires through the center hole of the bracket. Leave enough slack to connect them to the doorbell.

Step 6: Connect the Wires to the Doorbell

Now it’s time to wire the eufy doorbell.

Open the Terminal Cover

On the back of the eufy doorbell, you’ll see two terminal screws labeled “Front” and “Trans.” Loosen them slightly.

Insert the Wires

Insert the “Front” wire into the “Front” terminal and the “Trans” wire into the “Trans” terminal. Tighten the screws securely. Don’t overtighten—this can damage the threads.

Double-Check Connections

Gently tug on each wire to ensure it’s firmly in place. Loose wires cause power issues and unreliable performance.

Attach the Doorbell to the Bracket

Align the doorbell with the mounting bracket and press it into place. You should hear a click when it locks. Secure it with the provided security screw using a screwdriver.

Step 7: Install the Chime Module (If Needed)

If you’re replacing a mechanical chime inside your home, you’ll need to install the eufy chime module.

Turn Off Power Again

Go back to the breaker and confirm power is off before working inside the chime box.

Remove the Old Chime

Unscrew and remove the existing chime unit. Note how the wires are connected.

Connect the Chime Module

The eufy chime module connects in parallel with your existing chime wires. Follow the diagram in the quick start guide:

Connect the “Front” wire to the “Front” terminal.
Connect the “Trans” wire to the “Trans” terminal.
Connect the “Rear” wire (if you have a second door) to the “Rear” terminal.

Secure the Module

Mount the chime module inside the chime box using the provided screws. Close the cover.

Step 8: Restore Power and Test

You’re almost done! Now it’s time to power up and test.

Turn the Breaker Back On

Go to the electrical panel and turn the breaker back on. Wait a few seconds for the system to power up.

Check the Doorbell

The eufy doorbell should light up. You may see a blinking LED—this means it’s ready for setup.

Test the Button

Press the doorbell button. You should hear a chime inside (if installed) and see activity on the device.

Pro Tip: If nothing happens, turn the power off again and double-check all wire connections.

Step 9: Set Up the Eufy Security App

The app is where you configure settings, view video, and receive alerts.

Download and Open the App

Search for “eufy Security” in your app store and download it. Create an account or log in if you already have one.

Add a New Device

Tap the “+” icon and select “Doorbell.” Choose “Wired Doorbell” from the list.

Scan the QR Code

Point your phone’s camera at the QR code on the back of the doorbell or in the quick start guide. The app will detect the device.

Connect to Wi-Fi

Select your home Wi-Fi network and enter the password. The doorbell will connect to your network. This may take a minute.

Configure Settings

Customize your preferences:

Motion Detection Zones: Set areas where motion should trigger alerts.
Notification Preferences: Choose when and how you receive alerts.
Video Quality: Adjust resolution based on your Wi-Fi speed.
Two-Way Audio: Test the microphone and speaker.

Test Live View

Tap “Live View” to see the camera feed. Make sure the image is clear and the audio works.

Step 10: Final Adjustments and Mounting

Now that everything works, secure the installation.

Adjust the Angle

If the camera view is too high or low, loosen the security screw slightly and tilt the doorbell. Retighten when satisfied.

Seal the Edges

Use exterior-grade silicone caulk around the edges of the doorbell to prevent water intrusion, especially in rainy climates.

Label the Breaker (Optional)

If your breaker wasn’t labeled, now’s a good time to mark it “Doorbell” for future reference.

Troubleshooting Common Issues

Even with careful installation, problems can happen. Here’s how to fix the most common ones.

Doorbell Won’t Power On

Check the breaker—make sure it’s on.
Test the wires with a multimeter—ensure voltage is present.
