Before you grab your screwdriver, let’s make sure you have everything on hand. Rushing into installation without the right tools or info can lead to frustration—or worse, electrical hazards.

Here’s a quick checklist:

  • Your Eufy doorbell (wired model—battery versions can’t connect to chimes)
  • Existing doorbell chime (mechanical or digital)
  • Wire strippers
  • Screwdrivers (Phillips and flathead)
  • Voltage tester (non-contact type recommended)
  • Electrical tape
  • Optional: Eufy Chime Connector (sold separately, needed for some digital chimes)
  • Smartphone with Eufy Security app installed
  • Stable Wi-Fi connection

If you’re missing anything, don’t worry—most of these are common household tools. The Eufy Chime Connector is the only specialty item, and we’ll explain when you need it.

Step 1: Confirm Compatibility Between Your Eufy Doorbell and Existing Chime

Not all doorbells and chimes play nice together. Before you start wiring, it’s crucial to check if your setup will work.

Check Your Eufy Doorbell Model

First, confirm you have a wired Eufy doorbell. Battery-powered models like the Eufy Video Doorbell (battery version) cannot be connected to a chime—they rely solely on app notifications and optional Eufy chime accessories.

Wired models include:
– Eufy Video Doorbell (wired)
– Eufy Video Doorbell Dual (wired)
– Eufy Solo Doorbell (wired)

These models support chime connections, but only if your existing chime meets certain requirements.

Identify Your Existing Chime Type

There are two main types of doorbell chimes:

  • Mechanical chimes: These use an electromagnet to strike metal bars or bells. They make a traditional “ding-dong” sound and typically run on low-voltage AC power (8–24V). These are usually compatible with Eufy doorbells.
  • Digital chimes: These use electronic circuits and speakers to play recorded sounds. They may require specific voltage levels or have built-in resistors that interfere with smart doorbells. Some work with Eufy, but many need a special adapter.

To identify your chime:
– Look at the back or inside the chime box.
– Check for labels like “Mechanical,” “Digital,” or “Electronic.”
– If it has a transformer rating (e.g., 16V, 10VA), note that down.

Check Voltage Requirements

Eufy wired doorbells typically require **16–24V AC** from your doorbell transformer. Most homes have a transformer that outputs 16V, which is ideal.

To check your transformer:
1. Turn off power at the breaker.
2. Remove the chime cover.
3. Locate the transformer wires (usually connected to terminals labeled “Front” and “Trans” or “T”).
4. Use a multimeter to measure voltage across these wires (with power back on briefly).

If your voltage is below 8V or above 24V, you may need to replace the transformer. Eufy recommends 16V for best performance.

When You Need the Eufy Chime Connector

If you have a digital chime, especially one with a built-in resistor or “smart” features, you’ll likely need the **Eufy Chime Connector**. This small device sits between the doorbell and chime, regulating power and preventing damage.

You can buy it directly from Eufy’s website or Amazon. It’s not included with the doorbell, so plan ahead.

Without it, digital chimes may not ring, ring weakly, or cause the doorbell to malfunction.

Step 2: Turn Off Power and Remove the Old Doorbell

Safety first! Working with electricity is no joke. Even low-voltage doorbell systems can give a shock or damage your devices if mishandled.

Turn Off the Power

1. Go to your home’s electrical panel (breaker box).
2. Locate the breaker that controls your doorbell circuit. It’s often labeled “Doorbell,” “Chime,” or “HVAC.” If unsure, turn off the main breaker to be safe.
3. Use a non-contact voltage tester at the doorbell wires to confirm power is off. Touch the tester to the wires—if it beeps or lights up, power is still on.

Never skip this step. Even if you think the power is off, double-check.

Remove the Old Doorbell

1. Unscrew the old doorbell from the wall.
2. Gently pull it away to expose the two wires (usually labeled “Front” and “Trans”).
3. Loosen the terminal screws and disconnect the wires.
4. Cap the wires with wire nuts or electrical tape to prevent them from touching.

Set the old doorbell aside—you won’t need it anymore.

Step 3: Install the Eufy Doorbell Mounting Plate

Now it’s time to prep your Eufy doorbell for installation.

Choose the Right Mounting Plate

Eufy doorbells come with one or more mounting plates. Choose the one that best fits your doorframe and allows the doorbell to face forward.

If your doorframe is angled, use the included wedge mount to adjust the angle.

Secure the Mounting Plate

1. Hold the plate against the wall where you want the doorbell.
2. Use a level to ensure it’s straight.
3. Mark the screw holes with a pencil.
4. Drill pilot holes if needed (especially for brick or stucco).
5. Screw the plate into place using the provided screws.

Make sure it’s tight and secure—your doorbell will be hanging from this.

Connect the Wires

1. Strip about 1/4 inch of insulation from the ends of the two doorbell wires.
2. Loosen the terminal screws on the back of the mounting plate.
3. Insert one wire into each terminal (it doesn’t matter which wire goes where—doorbell circuits are not polarized).
4. Tighten the screws to secure the wires.

Double-check that the wires are firmly connected and not touching each other.

Step 4: Attach the Eufy Doorbell and Power It On

With the mounting plate in place and wires connected, it’s time to attach the doorbell.

Snap the Doorbell into Place

1. Align the Eufy doorbell with the mounting plate.
2. Gently press it until it clicks into place.
3. Secure it with the included anti-theft screw (use the special screwdriver provided).

This screw prevents someone from easily removing the doorbell.

Turn the Power Back On

1. Return to the breaker box and turn the power back on.
2. Wait 30–60 seconds for the doorbell to power up.

You should see lights on the doorbell (usually a blue or white LED). This means it’s receiving power and initializing.

Download and Open the Eufy Security App

If you haven’t already:
1. Download the Eufy Security app (iOS or Android).
2. Create an account or log in.
3. Tap “+” to add a new device.
4. Select your doorbell model and follow the on-screen instructions.

The app will guide you through Wi-Fi setup, firmware updates, and basic configuration.

Step 5: Connect the Doorbell to Your Existing Chime

This is the core of the process—getting your Eufy doorbell to trigger your old chime.

Understand How It Works

When someone presses the Eufy doorbell, it closes the circuit between the two wires, sending power to the chime. The chime then rings, just like with your old doorbell.

The key is ensuring the wiring path is complete and the chime receives the right signal.

Check the Chime Wiring

1. Remove the cover of your existing chime (usually held by screws).
2. Locate the terminals. Most chimes have three:
Front: Connects to the front doorbell.
Rear: Connects to a rear doorbell (if you have one).
Trans: Connects to the transformer.

Your Eufy doorbell will connect to the “Front” terminal.

Connect the Wires (No Chime Connector Needed)

If you have a mechanical chime and confirmed compatibility:

1. Ensure the two wires from your doorbell are still connected to the mounting plate.
2. These wires run from the doorbell, through the wall, to the chime.
3. At the chime, connect one wire to the “Front” terminal and the other to the “Trans” terminal.
4. Tighten the screws.

The circuit is now complete: power flows from the transformer → chime → doorbell → back to transformer.

When the doorbell button is pressed, the circuit closes, and the chime rings.

Connect the Wires (With Eufy Chime Connector)

If you have a digital chime or were advised to use the connector:

1. Disconnect the wires from the chime’s “Front” and “Trans” terminals.
2. Connect the two doorbell wires to the input side of the Eufy Chime Connector (labeled “Doorbell”).
3. Connect two new wires (included with the connector) from the output side of the connector to the chime’s “Front” and “Trans” terminals.
4. Secure all connections.

The connector acts as a buffer, ensuring the digital chime gets the right power signal without damaging the Eufy doorbell.

Test the Chime

1. Press the doorbell button.
2. Listen for the chime.

If it rings—great! You’re done.

If not, move to the troubleshooting section below.

Step 6: Configure Settings in the Eufy App

Even with the chime working, you’ll want to customize your doorbell’s behavior.

Adjust Motion and Ring Settings

In the Eufy app:
– Set motion detection zones.
– Adjust sensitivity to avoid false alerts.
– Choose notification preferences (push, email, etc.).

Enable or Disable Chime in App

Some Eufy models allow you to toggle the chime on or off in the app. This is useful if you only want the physical chime to ring at certain times.

Go to:
– Device Settings → Chime Settings → Toggle “Chime” on or off.

Note: This doesn’t affect your existing chime—it only controls whether the doorbell sends a signal to it.

Update Firmware

Always keep your doorbell updated:
– Go to Device Settings → Firmware Update.
– Install any available updates.

Updates improve performance, fix bugs, and add new features.

Troubleshooting: What to Do If the Chime Doesn’t Work

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

No Sound from the Chime

  • Check power: Is the breaker on? Use a voltage tester at the chime terminals.
  • Check wiring: Are the wires securely connected? Are they stripped properly?
  • Test the chime: Disconnect the doorbell wires and briefly touch them together. If the chime rings, the issue is with the doorbell or wiring path.
  • Try the doorbell alone: Temporarily connect the doorbell directly to the transformer (bypassing the chime). If it works, the chime may be faulty or incompatible.

Chime Rings Weakly or Intermittently

  • Low voltage: Your transformer may be underpowered. Replace it with a 16V, 10–15VA transformer.
  • Loose connections: Tighten all terminal screws.
  • Wire damage: Check for frayed or corroded wires. Replace if needed.

Chime Rings Without Being Pressed

  • Short circuit: Wires may be touching. Inspect connections.
  • Faulty doorbell: The Eufy doorbell may be stuck in a closed position. Try resetting it (hold the setup button for 10 seconds).
  • Interference: Nearby electronics or poor wiring can cause false triggers. Relocate wires if possible.

Digital Chime Still Not Working

  • Use the Eufy Chime Connector: If you haven’t already, buy and install it.
  • Check compatibility list: Visit Eufy’s support page for a list of compatible digital chimes.
  • Replace the chime: If all else fails, consider upgrading to a mechanical chime or using the Eufy Wireless Chime (sold separately).

Tips for a Smooth and Long-Lasting Setup

Now that your doorbell is working, here are some pro tips to keep it running smoothly:

  • Label your wires: Use tape to mark “Front” and “Trans” wires for future reference.
  • Use wire nuts: When capping unused wires, use proper wire nuts—not just tape.
  • Keep the app updated: Regularly check for app and firmware updates.
  • Clean the doorbell: Wipe the lens and sensor monthly to maintain video quality.
  • Test monthly: Press the button once a month to ensure everything still works.
