Eufy, known for its smart, user-friendly home security products, offers a range of alarm systems that are easy to install, affordable, and packed with features. But even the best system won’t protect you if it’s not armed properly.

In this comprehensive guide, you’ll learn exactly how to arm Eufy alarm systems like a pro. Whether you’re using the Eufy Security app, a keypad, or voice commands, we’ll walk you through every method. You’ll also discover the different arming modes, how to avoid false alarms, and what to do if something goes wrong. By the end, you’ll feel confident managing your home security with ease.

What Is the Eufy Alarm System?

Before diving into the steps, let’s quickly cover what the Eufy alarm system is. Eufy offers a range of smart security products, including door/window sensors, motion detectors, cameras, and a central hub (like the Eufy HomeBase 2 or HomeBase 3). These devices work together to detect intrusions, alert you, and even trigger loud alarms to scare off intruders.

The system is designed to be DIY-friendly—no professional installation required. It connects via Wi-Fi or a local network (depending on the model), and everything is managed through the free Eufy Security app on your smartphone or tablet. You can arm and disarm the system remotely, view live camera feeds, and receive instant alerts.

Why Arming Your Eufy Alarm Matters

Arming your Eufy alarm isn’t just a suggestion—it’s essential. When the system is armed, it actively monitors your home for signs of unauthorized entry. If a door opens, a window breaks, or motion is detected in a restricted area, the alarm will sound and you’ll get a notification.

Without arming the system, your sensors are essentially “asleep.” That means even if someone breaks in, the alarm won’t go off, and you won’t be alerted. So, whether you’re leaving for work, going to bed, or heading on vacation, arming your Eufy alarm is a critical step in protecting your home and family.

Types of Eufy Arming Modes

Eufy offers several arming modes to fit your lifestyle. Understanding these modes helps you choose the right level of protection for any situation.

1. Away Mode

This is the most secure mode. It activates all sensors—doors, windows, and motion detectors. Use it when no one is home, like during the day while you’re at work or when you’re on vacation. If any sensor is triggered, the alarm will sound immediately.

2. Home Mode

Home mode is perfect for nighttime or when you’re relaxing at home. It arms door and window sensors but typically disables motion detectors inside the house. This way, you can move around freely without setting off the alarm. Some models allow you to customize which sensors are active in Home mode.

3. Custom Mode

For advanced users, Custom mode lets you choose exactly which sensors to arm. For example, you might arm only the front door and garage sensors while leaving the back door open for a pet. This flexibility is great for unique home layouts or specific security needs.

4. Geofencing (Auto-Arming)

Some Eufy systems support geofencing, which uses your phone’s location to automatically arm or disarm the system. When you leave a set radius (like your neighborhood), the system arms itself. When you return, it disarms. This feature is convenient but requires location permissions and a stable internet connection.

How to Arm Eufy Alarm Using the App

The Eufy Security app is the easiest and most powerful way to control your alarm system. Here’s how to arm it step by step.

Step 1: Open the Eufy Security App

Launch the app on your smartphone or tablet. Make sure you’re logged into your account and that your devices are connected. If this is your first time using the app, follow the setup wizard to pair your sensors and hub.

Step 2: Select Your Security System

If you have multiple Eufy systems (e.g., one for your home and one for a rental property), tap the correct one from the home screen.

Step 3: Choose an Arming Mode

Tap the “Arm” button, usually located at the bottom of the screen. You’ll see options for Away, Home, or Custom mode. Select the one that fits your current situation.

Step 4: Confirm and Wait for Activation

After selecting a mode, the app will show a countdown (usually 30 seconds) to give you time to exit the house. This is the exit delay. Once the countdown ends, the system is fully armed. You’ll see a green “Armed” status on the app.

Step 5: Check Sensor Status

Go to the “Devices” tab and review each sensor. Make sure doors and windows are closed and motion detectors are unobstructed. If a sensor shows “Open” or “Fault,” fix the issue before arming again.

Pro Tip: Use Quick Actions

The app allows you to create shortcuts. For example, you can add a “Goodnight” scene that arms Home mode, turns off lights, and locks smart doors—all with one tap.

How to Arm Eufy Alarm with a Keypad

If your Eufy system includes a wireless keypad (like the Eufy Keypad 2), you can arm the system without using your phone. This is great for family members who don’t have smartphones or for quick access near the door.

Step 1: Approach the Keypad

Stand within range of the keypad (usually within 30 feet of the hub). The keypad will light up when you press a button.

Step 2: Enter Your PIN

Type your 4- to 6-digit PIN. This is the same code you use to disarm the system. If you haven’t set one up, do so in the app under “Settings” > “User Management.”

Step 3: Select Arming Mode

After entering your PIN, press the button labeled “Away,” “Home,” or “Custom” (depending on your model). The keypad will beep and show a confirmation light.

Step 4: Exit the Premises

The system will start an exit delay (typically 30 seconds). Leave the house during this time. Once the delay ends, the alarm is armed.

Pro Tip: Use the “Panic” Button

Most keypads have a panic button (often red). Pressing it triggers the alarm immediately—useful in emergencies.

How to Arm Eufy Alarm with Voice Commands

If you have a smart speaker like Amazon Alexa or Google Assistant, you can arm your Eufy alarm using voice commands. This is perfect for hands-free control.

Step 1: Link Eufy to Your Smart Speaker

Open the Alexa or Google Home app. Go to “Skills & Games” or “Works with Google,” search for “Eufy Security,” and link your account.

Step 2: Discover Devices

Say, “Alexa, discover devices” or “Hey Google, sync my devices.” Your Eufy system should appear in the list.

Step 3: Use Voice Commands

Try these commands:

• “Alexa, arm Eufy in Away mode.”
• “Hey Google, set Eufy to Home mode.”
• “Alexa, is Eufy armed?”

The system will confirm your request with a voice response or app notification.

Pro Tip: Create Routines

In the Alexa or Google app, create a routine like “I’m leaving” that arms Away mode, turns off lights, and adjusts the thermostat—all with one command.

How to Set Up Entry and Exit Delays

Entry and exit delays prevent false alarms by giving you time to enter or leave without triggering the system.

Exit Delay

This is the time between arming the system and when it becomes active. For example, if you arm Away mode and leave, the system waits 30 seconds before monitoring sensors. This gives you time to close the door and walk away.

Entry Delay

When you return home, the system detects motion or an open door but waits (usually 30–60 seconds) before sounding the alarm. This gives you time to disarm the system using your phone, keypad, or PIN.

How to Adjust Delays

Open the Eufy app, go to “Settings” > “Alarm Settings” > “Delay Settings.” Choose your preferred duration for entry and exit delays. Most users find 30 seconds works well.

Pro Tip: Use a Longer Delay for Pets

If you have pets, consider a longer entry delay (60 seconds) to avoid accidental triggers when they run to the door.

How to Disarm Your Eufy Alarm

Disarming is just as important as arming. Here’s how to do it safely.

Using the App

Open the app, tap “Disarm,” and confirm. The system will turn off immediately.

Using the Keypad

Enter your PIN within the entry delay period. The system will disarm and stop the countdown.

Using Voice

Say, “Alexa, disarm Eufy” or “Hey Google, turn off Eufy alarm.”

Pro Tip: Auto-Disarm with Geofencing

Enable geofencing in the app so the system disarms automatically when you return home.

Troubleshooting Common Arming Issues

Sometimes, your Eufy alarm won’t arm. Here’s how to fix the most common problems.

Issue 1: “Sensor Open” Error

Cause: A door, window, or sensor is open or misaligned.
Fix: Check all sensors. Close doors and windows. Realign sensors if they’re loose. Replace batteries if low.

Issue 2: “Low Battery” Warning

Cause: One or more sensors have weak batteries.
Fix: Replace batteries in the affected sensors. Most Eufy sensors use CR2032 or AA batteries and last 1–2 years.

Issue 3: “Hub Offline”

Cause: The HomeBase hub isn’t connected to Wi-Fi or power.
Fix: Check power and internet connections. Restart the hub by unplugging it for 10 seconds.

Issue 4: App Not Responding

Cause: Poor internet or app glitch.
Fix: Close and reopen the app. Restart your phone. Ensure your phone and hub are on the same network.

Issue 5: False Alarms

Cause: Pets, drafts, or faulty sensors.
Fix: Adjust motion sensor placement. Use pet-immune modes. Test sensors monthly.

Best Practices for Arming Your Eufy Alarm

Follow these tips to get the most out of your system.

1. Test Monthly

Arm the system and trigger each sensor to ensure it works. Check app notifications and alarm volume.

2. Keep the App Updated

Eufy regularly releases updates with bug fixes and new features. Enable auto-updates in your app store.

3. Use Strong Wi-Fi
