– How to set up the Eufy Security app
– How to connect your HomeBase to WiFi
– How to pair your lock with the HomeBase
– How to test and troubleshoot your connection

Let’s get started!

Step 1: Check Your Eufy Lock Model and Requirements

Before you begin, it’s important to know exactly what you’re working with. Not all Eufy locks are created equal when it comes to connectivity.

Does Your Lock Need a HomeBase?

Most Eufy smart locks—including popular models like the Eufy Smart Lock Touch, Smart Lock C21, and Smart Lock C22—do not have built-in WiFi. Instead, they rely on a Eufy HomeBase (such as the HomeBase 2 or HomeBase 3) or a Eufy Security Hub to connect to your home network.

Only a few newer Eufy locks, like the Eufy Smart Lock U10, have built-in WiFi and can connect directly to your router. But even then, using a HomeBase is recommended for better range and reliability.

So, check your lock’s packaging or user manual. If it mentions “HomeBase required” or “works with Eufy Security System,” you’ll need one to enable WiFi features.

What You’ll Need

Before starting the setup, make sure you have:
– Your Eufy smart lock (installed on your door)
– A Eufy HomeBase or Security Hub (plugged in and powered)
– The Eufy Security app (downloaded on your smartphone)
– A smartphone with Bluetooth enabled
– Access to your home WiFi network (2.4 GHz only)
– Your WiFi network name (SSID) and password

Pro tip: If you don’t have a HomeBase yet, you can purchase one directly from Eufy’s website or major retailers like Amazon. The HomeBase 2 is compatible with most older locks, while the HomeBase 3 supports newer models and offers improved performance.

Step 2: Download and Set Up the Eufy Security App

The Eufy Security app is your command center for all things Eufy. It’s available for free on both iOS and Android devices.

Download the App

Open your device’s app store:
– On iPhone: Open the App Store and search for “Eufy Security”
– On Android: Open Google Play and search for “Eufy Security”

Download and install the app. Make sure you’re getting the official app from “Eufy Security”—not a third-party imitation.

Create an Account

Once installed, open the app and tap “Sign Up” to create a new account. You’ll need:
– A valid email address
– A strong password
– Your country/region

After entering your details, check your email for a verification link. Tap it to confirm your account.

Enable Permissions

The app will ask for permissions to access:
– Bluetooth (required for initial setup)
– Location (helps with device discovery)
– Notifications (so you get alerts)

Grant all necessary permissions. Without them, the app won’t function properly.

Log In

After verifying your email, log in to the app using your credentials. You’re now ready to add your devices.

Step 3: Set Up Your Eufy HomeBase

If you haven’t already set up your HomeBase, now is the time. This device is the heart of your Eufy security system.

Plug In the HomeBase

Connect your HomeBase to a power outlet using the included power adapter. Place it in a central location in your home—ideally within 30 feet of your front door, but not too close to metal objects or thick walls that can block signals.

Avoid placing it near microwaves, cordless phones, or other devices that emit radio frequencies.

Wait for the Light

When powered on, the HomeBase will show a solid blue light. This means it’s ready to connect.

If the light is blinking or red, refer to the troubleshooting section at the end of this guide.

Add HomeBase to the App

In the Eufy Security app:
1. Tap the “+” icon in the top-right corner.
2. Select “Add Device.”
3. Choose “HomeBase” from the list.
4. Follow the on-screen prompts.

The app will search for nearby HomeBase devices. When it finds yours, tap it to begin pairing.

Connect HomeBase to WiFi

Now, the app will ask you to connect your HomeBase to your home WiFi network.

Important: Eufy devices only work on 2.4 GHz networks. If your router broadcasts both 2.4 GHz and 5 GHz under the same name (SSID), you may need to temporarily separate them or ensure your phone is connected to the 2.4 GHz band.

Here’s how:
1. Make sure your phone is connected to your 2.4 GHz WiFi network.
2. In the app, select your network from the list.
3. Enter your WiFi password carefully—case-sensitive and no spaces.
4. Tap “Connect.”

The HomeBase will attempt to join your network. This may take 1–2 minutes.

Confirm Connection

Once connected, the HomeBase light will turn solid green. The app will confirm success and assign a name (like “HomeBase 2 – Living Room”).

You can rename it later in the app settings if needed.

Step 4: Pair Your Eufy Lock with the HomeBase

Now that your HomeBase is online, it’s time to connect your lock.

Wake Up the Lock

Approach your Eufy lock and wake it up by touching the keypad or pressing any button. The screen should light up.

If the lock is new, it may already be in pairing mode. If not, you’ll need to activate pairing manually.

Enter Pairing Mode

To put your lock in pairing mode:
1. Press and hold the “Settings” button (usually on the interior side of the lock) for 5 seconds.
2. The lock will beep and display “Pairing” on the screen.

Alternatively, some models require you to enter a code like “8888” followed by “#” to access settings.

Refer to your lock’s manual if you’re unsure.

Add the Lock in the App

Back in the Eufy Security app:
1. Tap the “+” icon.
2. Select “Add Device.”
3. Choose “Smart Lock” or your specific model.
4. The app will search for nearby locks.

When your lock appears, tap it to begin pairing.

Follow On-Screen Instructions

The app will guide you through the final steps:
– Confirm the lock’s serial number (usually on the interior plate)
– Wait for the lock to sync with the HomeBase

This process may take 30–60 seconds. You’ll hear a confirmation beep when successful.

Name Your Lock

Once paired, the app will ask you to name your lock—like “Front Door” or “Back Door.” Choose something clear and memorable.

You can also assign it to a room or zone in your home for better organization.

Step 5: Test Your Connection and Features

Now that everything is connected, it’s time to test your setup.

Check WiFi Status

In the Eufy Security app:
1. Go to “Devices.”
2. Tap your lock.
3. Look for a WiFi or signal icon.

A solid green icon means your lock is online and connected to the HomeBase.

If it shows “Offline” or “Weak Signal,” see the troubleshooting section below.

Test Remote Access

Try unlocking your door from the app while you’re away from home (or at least outside Bluetooth range). If it works, your WiFi connection is active.

You should also receive real-time notifications when someone locks or unlocks the door.

Enable Smart Features

With WiFi connected, you can now:
– Set up auto-lock timers
– Create temporary access codes for guests
– View access logs
– Integrate with Alexa or Google Assistant

To enable voice control:
1. Open the Eufy app.
2. Go to “Settings” > “Smart Assistant.”
3. Link your Amazon Alexa or Google account.
4. Say, “Alexa, unlock the front door” (after confirming security).

Note: For security, voice unlock may require a PIN or confirmation.

Step 6: Update Firmware and Enable Security Features

Keeping your devices updated is crucial for performance and security.

Check for Updates

In the Eufy app:
1. Go to “Devices.”
2. Tap your lock or HomeBase.
3. Look for “Firmware Update” or “System Update.”

If an update is available, tap “Update Now.” The device will download and install it automatically.

Do not unplug the device during an update.

Enable Two-Factor Authentication (2FA)

To protect your account:
1. Go to “Profile” > “Account Security.”
2. Tap “Two-Factor Authentication.”
3. Choose “SMS” or “Authenticator App.”
4. Follow the setup instructions.

With 2FA enabled, anyone trying to access your account will need a verification code.

Set Up Access Codes and Permissions

Now that your lock is online, you can manage who has access:
– Create permanent codes for family members
– Set temporary codes for guests (with expiration dates)
– Revoke access instantly from the app

You can also assign different permission levels—like “Admin” (full control) or “User” (unlock only).
