An Entry Sensor is a crucial component of a security system designed to detect unauthorized access through doors, windows, or other entry points. It consists of two parts: a magnetic sensor and a magnet. When the door or window is closed, the two parts remain aligned, creating a secure circuit. If the door or window is opened, breaking the magnetic connection, the sensor triggers an alert, notifying the security system.

Step 2: Add Entry Sensor

1. On the app’s main screen, tap the “+” icon in the top-right corner.     

2. Select “Alarm System” under the Security section, choose eufy Entry Sensor and the designated home (where your HomeBase Professional is at) .  

Step 3: Connecting Entry Sensor E20 to HomeBase Professional S1

Install and Test entry sensor

Step 1: Choose a suitable installation location and preferred installation method

1. After pairing is successful, click "Next" and you will see the installation notes.

2. We provide two ways of fixing: adhesive and screws. You can check the installation tutorial in the installation guide or App.

Step 2: Test whether the entry sensor is working properly

1. After the installation is complete, you need to test whether the entry sensor can be triggered in time and receive a message on the phone. If you successfully receive the event reminder, it means the installation is successful.

2. If you are unable to receive an event, please contact us for assistance.

Additional Features

1. The entry sensor is designed with flexibility in mind — the magnet can be placed on either side of the sensor, making installation easier and more adaptable to your door or window setup.
   
   

2. The sensor also features a convenient button that allows you to activate the Bypass function. By physically pressing and holding the button for two seconds, the sensor will enter a 120-second bypass mode, during which it will not be triggered. This gives you a short window to pass through without setting off the alarm.

Troubleshooting Tips

1. Why doesn't the LED blink?

   1. Try to press the Sync button longer until the LED blinks

   2. Please check if you have installed the battery with the right +/- direction

   3. If you confirm that the battery +/- is right, please buy a new battery and retry.
