Step 1: Check Hub Compatibility

Ensure you have a SmartThings Hub, SmartThings WiFi, or a compatible Samsung device (like certain Samsung TVs or Family Hub refrigerators) that can act as a hub.

Step 2: Open the SmartThings App

Download the SmartThings app if you don't have it. Open the app and sign in to your Samsung account.

Step 3: Add the Device

In the app, tap the "+" icon and select "Add device." Choose the "Motion sensor" category from the device list.

Step 4: Prepare the Sensor

Remove the tab on the Motion Sensor marked "Remove When Connecting." This activates the sensor and puts it in pairing mode.

Step 5: Complete Pairing

Keep the sensor within 15 feet (4.5 meters) of your hub during setup. Follow the on-screen instructions to complete the connection.

Step 6: Position the Sensor

Place or mount the sensor in your desired location. The sensor can detect motion up to 15 feet away with a 120-degree field of view. Ideal locations include hallways, entryways, or rooms you want to monitor.

Creating Automations

Select your motion sensor in the SmartThings app and tap "Routines" to create automations:

Turn on lights when motion is detected
Turn off lights after no motion for a set time
Trigger specific actions only during certain hours
Send notifications when motion is detected
