Why Hardwire Your Eufy Doorbell?

Before we dive into the installation, let’s talk about why hardwiring matters.

Many Eufy doorbells come with rechargeable batteries, which is convenient—but not ideal if you want constant recording and instant alerts. Batteries drain faster in cold weather, and frequent recharging can be a hassle.

Hardwiring your Eufy doorbell solves these problems. It provides continuous power, ensures reliable performance, and eliminates the need for battery swaps. Plus, hardwired models often support advanced features like continuous recording and faster response times.

But not all Eufy doorbells can be hardwired. Only certain models—like the Eufy Video Doorbell Dual, Eufy Video Doorbell Solo (wired version), and Eufy Security Doorbell Wired—are designed for permanent electrical connection. Battery-only models cannot be hardwired.

So before you start, double-check your model. Look for “Wired” in the product name or check the packaging and user manual.

Tools and Materials You’ll Need

Gather these items before you begin. Having everything ready will make the process smoother and safer.

• Screwdriver set: Phillips and flathead for removing plates and securing wires.
• Voltage tester: To confirm power is off before touching wires.
• Wire strippers: For exposing fresh wire ends.
• Electrical tape: To insulate connections.
• Drill and drill bits: Only if you need to make new holes for mounting.
• Wall anchors and screws: Usually included with the doorbell, but have extras handy.
• Ladder: For safe access to the doorbell location.
• Smartphone with Eufy app: For setup and testing.

Optional but helpful:

• Wire nuts (if extending wires)
• Fish tape (for running new wires through walls)
• Multimeter (to test voltage)

Step 1: Turn Off Power at the Breaker

Safety first! Working with electricity is risky if you don’t take precautions.

Locate Your Electrical Panel

Find your home’s main electrical breaker box. It’s usually in the basement, garage, or utility closet.

Identify the Doorbell Circuit

Look for a breaker labeled “doorbell,” “chime,” or “low voltage.” If it’s not labeled, turn off breakers one by one and test the doorbell button until it stops working.

Turn Off the Breaker

Switch the correct breaker to the “OFF” position. Use a voltage tester on the doorbell wires to confirm no power is flowing.

Pro Tip: Place a piece of tape over the breaker switch with a note like “Do not turn on—working on doorbell.” This prevents someone from accidentally restoring power while you’re working.

Step 2: Remove the Old Doorbell (If Applicable)

If you’re replacing an existing doorbell, you’ll need to remove it first.

Unscrew the Faceplate

Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the unit away from the wall.

Disconnect the Wires

You’ll see two wires connected to terminals (usually labeled “Front” and “Trans”). Loosen the screws and carefully pull the wires free.

Cap the Wires

Twist wire nuts over the exposed ends to prevent them from touching each other or the wall. This keeps them safe until you’re ready to reconnect.

Remove the Mounting Plate

If the old plate doesn’t match the Eufy doorbell, remove it completely. You’ll install the new Eufy mounting plate in the next step.

Step 3: Check Your Existing Wiring and Transformer

Not all doorbell systems are created equal. Your Eufy doorbell needs the right voltage and power to work properly.

Test the Voltage

Use a multimeter set to AC voltage. Touch the probes to the two doorbell wires. You should see a reading between 16V and 24V AC.

If the voltage is below 16V, your doorbell may not power on reliably. If it’s above 24V, it could damage the doorbell.

Check the Transformer Rating

The transformer (usually located near your chime unit or furnace) should be rated for at least 20VA (volt-amperes). Look for a label that says “16V 20VA” or “24V 30VA.”

If your transformer is underpowered (e.g., 8V or 10V), you’ll need to replace it. A weak transformer can cause the doorbell to reboot, lag, or fail to record.

Note: Some homes have transformers built into the chime unit. If you’re unsure, consult an electrician.

Inspect the Wires

Make sure the wires are in good condition—no fraying, corrosion, or damage. If the wires are too short or damaged, you may need to extend them or run new ones.

Step 4: Install the Eufy Mounting Plate

Now it’s time to prepare the Eufy doorbell for mounting.

Choose the Right Mounting Plate

Eufy doorbells come with one or more mounting plates. Use the standard plate for flat surfaces. If your wall is angled or you want a better viewing angle, use the wedge mount (included with some models).

Position the Plate

Hold the mounting plate against the wall where you want the doorbell. Make sure it’s level and at a comfortable height (about 48 inches from the ground is standard).

Mark the Screw Holes

Use a pencil to mark where the screws will go. If the holes don’t align with existing ones, you’ll need to drill new ones.

Drill and Secure

Drill pilot holes if needed, insert wall anchors, and screw the plate into place. Make sure it’s tight and secure—this will hold your doorbell.

Route the Wires

Feed the two doorbell wires through the center hole in the mounting plate. Leave about 6 inches of wire exposed for connection.

Step 5: Connect the Wires to the Eufy Doorbell

This is the core of how to hardwire Eufy doorbell—making the electrical connection.

Identify the Terminals

On the back of the Eufy doorbell, you’ll see two terminals labeled “L” (Line) and “N” (Neutral), or sometimes just two screw terminals without labels. Either way, there are two connection points.

Strip the Wire Ends

Use wire strippers to remove about 1/4 inch of insulation from each wire. You want clean, bare copper exposed.

Connect the Wires

Loosen the terminal screws, insert one wire into each terminal, and tighten the screws securely. It doesn’t matter which wire goes where—doorbell circuits are not polarized.

Pro Tip: Twist the wire ends slightly before inserting them to prevent fraying and ensure a solid connection.

Secure with Electrical Tape (Optional)

For extra safety, wrap electrical tape around the base of the terminals to prevent accidental shorts.

Step 6: Attach the Doorbell to the Mounting Plate

With the wires connected, it’s time to mount the doorbell.

Align the Doorbell

Hold the Eufy doorbell against the mounting plate. The hooks or slots on the back should align with the plate.

Slide into Place

Gently slide the doorbell downward until it clicks or locks into position. You should feel it secure.

Secure with Screw (If Applicable)

Some models include a security screw to prevent theft. Use the provided screw and screwdriver to fasten the doorbell to the plate.

Step 7: Restore Power and Test

Now that everything is connected, it’s time to power up.

Turn the Breaker Back On

Go to your electrical panel and switch the doorbell breaker to “ON.”

Wait for the Doorbell to Power Up

The Eufy doorbell should light up and begin initializing. This may take 30–60 seconds.

Check for Power Indicators

Look for a solid light on the doorbell. A solid white or blue light usually means it’s powered and ready.

If the light doesn’t come on, double-check your wiring, voltage, and breaker.

Test the Doorbell

Press the button. You should hear a chime (if connected) and see activity in the Eufy app.

Step 8: Set Up the Eufy App

Even if your doorbell is hardwired, you still need to connect it to Wi-Fi and configure settings.

Download the Eufy App

Available on iOS and Android. Search “Eufy Security” in your app store.

Create or Log In to Your Account

Follow the prompts to sign up or log in.

Add the Doorbell

Tap the “+” icon and select “Add Device.” Choose your doorbell model and follow the on-screen instructions.

Connect to Wi-Fi

The app will guide you through connecting the doorbell to your home Wi-Fi network. Make sure you’re within range of your router.

Pair with Chime (If Using)

If you have a Eufy chime, the app will help you pair it. Press the sync button on the chime when prompted.

Test Two-Way Audio and Motion Detection

Speak into the app and listen through the doorbell. Walk in front of it to test motion alerts.

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 that the breaker is on.
• Use a multimeter to test voltage at the wires.
