Let’s get started!

Why Connect Eufy Doorbell to an Existing Chime?

Before diving into the installation, it’s worth understanding why connecting your Eufy doorbell to an existing chime is a smart move.

First, cost savings. Eufy doorbells are already affordable compared to competitors like Ring or Nest, but skipping the need for a new chime saves you even more. Many Eufy models come with a wireless chime, but if you already have a working one, there’s no need to replace it.

Second, familiarity and convenience. If your current chime is in a central location—like the kitchen or living room—you probably already know where to listen for visitors. Reusing it means no adjustment period.

Third, better sound coverage. Some existing chimes are louder or have better acoustics than the included Eufy chime. If your current one fills the house with sound, why change it?

Finally, eco-friendly choice. Reusing existing hardware reduces electronic waste and supports sustainable home upgrades.

So, if your existing chime is in good condition and compatible, connecting it to your Eufy doorbell is a win-win.

What You’ll Need

Before you begin, gather these tools and materials to ensure a smooth installation:

• Eufy doorbell (wired model, such as Eufy Video Doorbell 2K or Eufy SoloCam D210)
• Existing doorbell chime (mechanical or digital)
• Screwdriver (usually Phillips head)
• Voltage tester (optional but recommended)
• Smartphone with the Eufy Security app installed
• Stable Wi-Fi connection (2.4 GHz band required)
• Ladder (if your doorbell is mounted high)
• Electrical tape (for securing wires)
• Wire strippers (if trimming wires is needed)

Make sure your Eufy doorbell is a wired model, as wireless versions (like the Eufy Battery Doorbell) don’t connect directly to existing chimes. Only wired Eufy doorbells can interface with your home’s doorbell wiring and chime.

Step 1: Check Compatibility with Your Existing Chime

Not every chime works with Eufy doorbells. Before you start, you need to confirm compatibility.

Determine Your Chime Type

There are two main types of doorbell chimes:

• Mechanical chimes: These use an electromagnet to strike metal bars, creating the classic “ding-dong” sound. They’re common in older homes and typically run on low-voltage AC power (8–24V).
• Digital chimes: These use electronic circuits and speakers to play recorded tones or melodies. They’re found in newer homes and may require a transformer with specific voltage and frequency.

To identify your chime type, look inside the chime box (after turning off power—more on that soon). Mechanical chimes have visible metal bars and coils. Digital chimes have circuit boards and small speakers.

Check Voltage Requirements

Eufy wired doorbells require a transformer that outputs 8–24V AC. Most homes have transformers in this range, but it’s important to verify.

Use a multimeter or voltage tester to measure the voltage at the doorbell terminals (again, with power off and wires disconnected). If your transformer outputs less than 8V, the doorbell may not work reliably. If it’s over 24V, you risk damaging the device.

If your transformer is incompatible, you may need to replace it—but this is rare. Most homes have suitable transformers.

Confirm Chime Compatibility

Eufy doorbells are designed to work with most standard mechanical and digital chimes. However, some very old or proprietary chimes (like those from certain intercom systems) may not be compatible.

If your chime is more than 20 years old or part of a complex system, check Eufy’s official compatibility list or contact customer support.

As a general rule: if your old doorbell worked with the chime, your Eufy doorbell should too—as long as the wiring and transformer are in good condition.

Step 2: Turn Off Power at the Breaker

Safety first! Before touching any wires, you must turn off the power to your doorbell circuit.

Locate the Correct Breaker

Doorbell circuits are usually on a dedicated 15–20 amp breaker labeled “Doorbell,” “Chime,” or “Front Door.” If you can’t find it, turn off the main breaker to be safe.

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. Wait and recheck.

Label the Wires

Once power is off, remove the old doorbell button. You’ll see two wires: usually labeled “Front” and “Trans” (transformer). Use tape to label them so you don’t mix them up during installation.

If your home has multiple doors (front and back), make sure you’re working on the correct circuit.

Step 3: Remove the Old Doorbell

Now it’s time to take out the old doorbell.

Unscrew the Mounting Plate

Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the device away, exposing the two wires.

Disconnect the Wires

Loosen the terminal screws and remove the wires. Don’t let them fall back into the wall—use electrical tape to secure them to the wall or hold them with your fingers.

If the wires are short or damaged, you may need to strip the ends to expose fresh copper (about 1/4 inch).

Step 4: Install the Eufy Doorbell

Now you’re ready to install your Eufy doorbell.

Attach the Mounting Plate

Hold the Eufy mounting plate against the wall, aligning it with the existing holes. Use the included screws to secure it. If the holes don’t line up, you may need to drill new ones (use wall anchors for brick or concrete).

Connect the Wires

Connect the two wires to the terminals on the back of the Eufy doorbell. It doesn’t matter which wire goes where—Eufy doorbells are non-polarized.

Tighten the terminal screws securely. Make sure no bare wire is exposed outside the terminals.

Attach the Doorbell

Snap the Eufy doorbell onto the mounting plate. You should hear a click when it’s secure.

Step 5: Power On and Open the Eufy App

Now it’s time to bring everything to life.

Turn the Power Back On

Go to your breaker panel and turn the doorbell circuit back on. The Eufy doorbell should power up—you’ll see lights or hear a chime.

Download and Open the Eufy Security App

If you haven’t already, download the Eufy Security app from the App Store (iOS) or Google Play (Android). Create an account or log in.

Add Your Device

Tap the “+” icon in the app and select “Doorbell.” Follow the on-screen instructions to scan the QR code on your doorbell or enter the serial number manually.

The app will guide you through Wi-Fi setup. Make sure your phone is connected to the same 2.4 GHz Wi-Fi network your doorbell will use. Eufy doorbells do not support 5 GHz networks.

Step 6: Configure the Chime Settings

This is where the magic happens—connecting your Eufy doorbell to your existing chime.

Enable Chime in the App

In the Eufy app, go to your doorbell’s settings. Look for “Chime” or “Doorbell Chime” options.

Toggle on “Use Existing Chime” or “Enable Chime.” Some models may call this “Mechanical Chime” or “Digital Chime.”

Select Chime Type

Choose whether your chime is mechanical or digital. This helps the doorbell send the correct signal.

If you’re unsure, start with “Mechanical”—it’s the most common.

Adjust Chime Duration (Optional)

Some Eufy models let you set how long the chime signal lasts (e.g., 1 second, 2 seconds). Longer durations may be needed for digital chimes.

Start with the default setting and adjust if needed.

Step 7: Test the Doorbell and Chime

Now it’s time to test everything.

Press the Doorbell Button

Have someone press the doorbell button while you listen for the chime.

You should hear your existing chime ring—just like with the old doorbell.

Check the App Notification

You should also receive a push notification on your phone, and the live video feed should appear in the app.

If both the chime and app work, congratulations—you’ve successfully connected your Eufy doorbell to your existing chime!

Troubleshooting Common Issues

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