How to Set Up Your SwitchBot Contact Sensor (Matter)

What You'll Need

• SwitchBot Contact Sensor (Matter version)
• SwitchBot Hub 2 or Hub Mini (Matter-enabled) already set up
• SwitchBot app installed on your smartphone
• Matter-compatible smart home platform (Apple Home, Google Home, Amazon Alexa, SmartThings)
• 2.4GHz WiFi network

Step-by-Step Setup

1. Prepare the sensor: Remove the battery tab from the back of the sensor. The LED will flash briefly to indicate power.
2. Open the SwitchBot app: Tap the "+" icon in the top right corner and select "Contact Sensor" from the device list.
3. Put sensor in pairing mode: Press and hold the reset button on the sensor for 3 seconds until the LED flashes rapidly.
4. Connect to hub: The app will detect the sensor. Select your SwitchBot Hub to link the sensor.
5. Name and place: Give your sensor a name (e.g., "Front Door") and choose its location.
6. Enable Matter: In the sensor settings, tap "Matter Setup" and select your target platform.
7. Scan Matter code: Use your smart home app to scan the Matter QR code displayed in SwitchBot.
8. Mount the sensor: Use the included adhesive strips to mount the main sensor on the door frame and the magnet on the door, aligned within 15mm of each other.

Key Features

• Open/close detection: Real-time status monitoring for doors and windows
• Motion detection: Built-in PIR sensor detects movement in front of the door
• Light detection: Ambient light sensor for automation triggers
• Entry alerts: Immediate notifications when door opens or closes
• Left open reminders: Configurable alerts if door stays open too long
• History log: Track all open/close events with timestamps

Troubleshooting

• Sensor not pairing: Ensure sensor is within 5 meters of the hub during setup. Hold reset button until LED flashes rapidly.
• Delayed status updates: Check that hub has strong WiFi connection. Matter status may have slight delay compared to native SwitchBot.
• Incorrect open/close state: Verify magnet alignment with sensor. Gap should be less than 15mm when closed.
• Matter setup fails: Update SwitchBot Hub firmware. Ensure hub supports Matter (Hub 2 or updated Hub Mini).
• Battery draining quickly: Reduce motion detection sensitivity or disable if not needed.
