4. Operating Instructions

The sensor's multi-functional capabilities allow for diverse applications in your smart home.

4.1 Understanding Sensor Modes

The sensor offers configurable detection modes to suit different environments and preferences:

• Radar Only: Detects presence using millimeter wave radar.
• Radar and Auxiliary Infrared: Enhanced detection by combining radar with auxiliary infrared.
• Radar and Infrared: Utilizes both radar and primary infrared for comprehensive detection.
• Infrared Only: Detects presence using only the infrared sensor.

These modes can typically be adjusted within your smart home application's device settings.

4.2 Smart Home Integration and Scenarios

Leverage the sensor's data for various automations:

• Lighting Control: Automatically turn lights on when presence is detected and off when a room is vacant. Adjust light brightness based on ambient light levels detected by the sensor.
• Appliance Control: Trigger smart appliances (e.g., TV, air conditioning) upon entry or exit.
• Home Security: Use presence detection for security monitoring and alerts.
• Environmental Monitoring: Monitor temperature and humidity to adjust HVAC systems or trigger alerts.

5. Maintenance

To ensure optimal performance and longevity of your LeTianPai Presence Sensor Box, follow these maintenance guidelines:

• Cleaning: Gently wipe the sensor's exterior with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the device.
• Firmware Updates: Regularly check for and install firmware updates through your connected smart home application. Updates often include performance improvements, bug fixes, and new features. The device supports Over-The-Air (OTA) updates.
• Placement: Ensure the sensor is placed in an area free from obstructions that could interfere with its detection capabilities. Avoid direct sunlight or strong drafts that might affect temperature and humidity readings.

6. Troubleshooting

If you encounter issues with your LeTianPai Presence Sensor Box, refer to the following troubleshooting tips:

• Device Not Responding:
  • Verify the USB-C power connection. Ensure the sensor is receiving power.
  • Check your Wi-Fi network and Matter hub connectivity.
  • Attempt to restart the sensor by unplugging and re-plugging the USB-C cable.
• Inaccurate Temperature/Humidity Readings:
  • Ensure the sensor is not placed near heat sources (e.g., direct sunlight, vents, appliances) or in areas with significant drafts.
  • Allow some time for the sensor to stabilize after initial setup or relocation.
  • Check for available firmware updates, as these can improve sensor accuracy.
• Slow Response in Apple Home/Other Platforms:
  • Ensure your smart home hub and the sensor have the latest firmware.
  • Verify network stability and signal strength between the sensor and your Matter hub.
  • If issues persist, try re-pairing the device with your smart home platform.
• Detection Issues (False Alerts or No Detection):
  • Review the sensor's placement to ensure there are no obstructions blocking its field of view.
  • Adjust the detection mode and sensitivity settings within your smart home application.
  • Ensure the detection range is appropriate for the room size.
• Difficulty with Manufacturer App (if applicable):
  • Since the device is Matter-enabled, direct use of a manufacturer app may not be necessary for core functionality. Focus on integration with your primary Matter-compatible smart home platform.
  • If a specific manufacturer app is desired, ensure it is the latest version and compatible with your device.
