Note on Detection Distance: The detection distance refers to the maximum linear distance from the sensor to a target (moving, micro-moving, or breathing). It is not the maximum diameter or radius mapped to the ground. The sensor has a distance resolution of approximately 1m. For example, if set to 3m, triggering within ±1m of the 3m position is considered normal. The distance value is primarily for filtering through glass partitions, gypsum boards, and wooden partitions, not for strict area division in presence detection.

4. Installasie

4.1 Installasiebeginsels

  • General Indoor Areas (Hallways, Changing Rooms, Kitchens): Install as centrally and firmly as possible.
  • Bathrooms/Toilets: Install 0.4-0.6m in front of the top of the toilet/squatting position, away from doors, windows, and exhaust fans.
  • Living Room/Dining Room/Conference Room: Position 0.5-1m in front of the sofa, directly above the table.
  • Bedroom/Study: Directly above the bed, or within 0.6-1.5m behind/in front of the desk.
  • Glass/Gypsum Board Partitions: Position the sensor as close to a solid wall as possible. If only glass/gypsum walls are present, install centrally and adjust detection range and sensitivity to prevent false detections outside the intended area.
  • Sitting, Squatting, Standing Still Scenes: For ceiling-mounted sensors, position 0.4-0.8m in front of the head's top. Avoid direct overhead installation. Wall-mounted sensors are generally better for detecting sitting still.
  • Dense Deployment: Maintain a linear spacing of at least 5m between sensors.

4.2 Muur-gemonteerde installasie

  1. Ensure the installation location is 1.5 to 2 meters above the ground.
  2. Power the sensor using a 5V 1A USB power supply.
  3. Apply the provided double-sided adhesive to the back of the wall-mounted sensor.
  4. Firmly attach the sensor to the desired wall position.
Dimensions of the wall-mounted sensor: 58mm by 58mm by 11mm.

4.3 Ceiling-Mounted Installation

  1. Create an opening in the ceiling with a diameter of 53-58mm (55mm recommended).
  2. Connect the sensor to an 80-240VAC power supply.
  3. Insert the sensor into the ceiling opening and secure it using the two end buckles.
  4. It is recommended to complete network configuration before final installation in the ceiling.
Dimensions of the ceiling-mounted sensor: 61mm diameter, 39mm height, with an opening size of 53-58mm.

5. Setup & App Operation

5.1 App-installasie

To control your sensor, download the "Tuya Smart" or "Smart Life" app from your device's app store. Alternatively, you can scan the QR code provided in the original PDF user manual for direct download. After installation, register and log in to your account.

5.2 Device Network Connection

For initial use, the sensor needs to be connected to your network. ZigBee versions require a ZigBee gateway (hub), while Wi-Fi versions connect directly to your Wi-Fi network.

  1. Krag aan: Upon first power-on or if not yet networked, the device will automatically enter pairing mode. The red indicator light will flash quickly. If pairing fails or the red light does not flash, re-power the device or press and hold the network button for more than 5 seconds to re-enter pairing mode.
  2. Voeg toestel in toepassing by: Open and log in to the Tuya Smart/Smart Life app. Tap the "+" symbol in the upper right corner and select "Add Device".
  3. Discovery & Confirmation: The app will search for nearby devices. Once your sensor is discovered, tap "Add". After successful addition, the sensor's red indicator light will turn off.

5.3 ZigBee2mqtt Support

To integrate your ZigBee sensor with ZigBee2mqtt, ensure your ZigBee2mqtt installation is updated to the latest version. If issues persist, you may need to download the specific JS file and configure it according to the documentation available at: https://github.com/wzwenzhi/Wenzhi-ZigBee2mqtt

6. Bedryfsinstruksies

6.1 Detection Functions

The sensor provides various detection capabilities:

  • Fretting Detection: Detects small movements like tilting the head, waving, raising a hand, flicking the body, playing with a mobile phone, or turning a book page.
  • Teenwoordigheidsbespeuring: Detects the human body in a stationary state (e.g., standing still, squatting still, sitting still).
  • Bewegingsopsporing: Detects larger movements such as walking, jogging, fast running, circling, or jumping.
  • Afstandmeting: Accurately filters targets outside a specified area based on their distance from the sensor.

6.2 Luminance Detection

The sensor includes an illuminance monitor (0-2000 LUX) that can be used in the Tuya Smart app for smart scene linkages. For example, you can configure your house lights to turn ON/OFF automatically based on changes in ambient brightness.

6.3 Adjustable Parameters

A variety of parameters can be adjusted via the Tuya Smart Life app to customize the sensor's behavior:

  • Sensitiwiteit: Adjustable from 1-9 (default 7) to fine-tune detection.
  • Bespeuringsreeks: Set minimum (e.g., 0.00m) and maximum (e.g., 9.5m) detection distances.
  • Unmanned Delay (Hold Time): Configurable from 5-1500 seconds (default 15s) to determine how long the sensor waits after no presence is detected before changing state.
  • Presence Confirmation Delay: Adjustable from 0-100 seconds (default 0.1s) to confirm presence.
  • Verslaginterval: Sets the frequency of data reporting (1-3600s, default 5s). Note that detection status changes are reported immediately, regardless of this setting.

7. Probleemoplossing

Here are common interference sources and recommended solutions:

  • fan: Change the position of the fan or sensor. Ensure the fan is outside the presence detection area.
  • Lugversorging: The air swing and louver vibration of the AC should be outside the sensor's presence detection area.
  • Rolling Shutter with Aluminum Alloy Lower Rail: Set an appropriate detection range to filter out such interference.
  • Uitlaatwaaier: Avoid exhaust fans or vibrating surfaces within the sensor's detection range. Secure the exhaust fan to prevent ceiling vibration.
  • Strong 5.8GHz WiFi Signal Interference:
    • For WiFi routers in the front area of the sensor, maintain a distance of at least 3m.
    • For routers in other directions, maintain a distance of at least 1.5m.
    • When using a top-mounted Access Point (AP), maintain a distance of at least 1.5m from the sensor.
  • Air Flow (Wind): Adjust the sensor's sensitivity setting.
  • Diere: Adjust sensitivity and the nearest detection distance to minimize false triggers from pets.
  • Low-Frequency Vibration: Avoid direct exposure of radar signals to sound systems or other vibration sources. Set a relatively low sensitivity to prevent false triggering and use a longer presence confirmation delay time.
  • Restricted Usage Scenarios: Avoid installing in elevators, metal-sealed toilets, or similar all-metal sealed spaces. Also avoid scenarios where the plane area of metal decorative materials outside the non-ceiling area exceeds 20%.

8. Gebruikerswenke

  • ZigBee Sensor Lag: Some users report a communication delay (lag) of 5 to 10 seconds for battery-powered ZigBee presence sensors. While this sensor is mains-powered (80-240VAC or USB 5V), it's good practice to test its response time in your specific setup, especially for critical automation.
  • ZigBee2mqtt Integration: If you're using ZigBee2mqtt, always ensure it's updated to the latest version for best compatibility and performance with your Wenzhi ZigBee sensor. Refer to the official Wenzhi GitHub for specific configuration files indien nodig.
