4.3 Pairing with Zigbee Hub and Tuya Smart Life APP
- Ensure your Zigbee Hub is powered on and connected to your home network.
- Open the Tuya Smart Life APP on your smartphone.
- Follow the in-app instructions to add a new device. Select 'Sensor' or 'Motion Sensor' category.
- Put the motion sensor into pairing mode (refer to the specific instructions for your Zigbee Hub and the sensor's pairing button, usually a long press).
- Once detected, confirm the device in the app and assign it to a room or group.
4.4 Mounting the Sensor
The sensor offers two primary installation methods:
- Wall Mount: Use the provided adhesive or screws to attach the magnetic base to a wall. The sensor can then be magnetically attached to the base, allowing for easy angle adjustment.
- Desktop Placement: Place the sensor on any flat surface, such as a table, shelf, or cabinet. The magnetic base provides stability and allows for flexible positioning.
For optimal performance, install the sensor at an approximate height of 2.2 meters (depending on the center of the product) to cover the desired detection area effectively.

5. Operating Instructions
5.1 Motion Detection
Once installed and paired, the sensor will continuously monitor its detection zone for human movement. When motion is detected, it will send a signal to your Zigbee Hub and subsequently to the Tuya Smart Life APP.
The sensor provides 24/7 guarding by detecting movement in its coverage area.
Examples of detection range in various room configurations.
5.2 Real-time Notifications & History
The Tuya Smart Life APP will provide real-time notifications whenever motion is detected. You can also view a detailed history of all detection events within the app, allowing you to monitor activity over time.
The Smart Life app displays a record of motion detection events.
5.3 Smart Linkage and Automation
Leverage the Tuya Smart Life APP to create smart scenes and link the motion sensor with other AVATTO smart home devices. For example:
- Entryway Lighting: When motion is detected in the entryway, turn on the smart lights.
- Security Alert: If motion is detected while you are away, trigger an alarm or send a notification to your phone.
- Energy Saving: Turn off lights or appliances in a room if no motion is detected for a set period.

5.4 Adjusting Detection Angle
Thanks to its magnetic base, the sensor's detection angle can be easily adjusted by simply repositioning the sensor on its base or by adjusting the base itself if wall-mounted. This allows for fine-tuning the coverage area to suit your specific needs.
6. Maintenance
6.1 Battery Replacement
The sensor is designed for long battery life (over 1 year with typical usage). When the battery level is low (Low Voltage Alarm Value: 2.5V ± 0.2V), you may receive a notification via the Tuya Smart Life APP. Replace the CR123A 3V battery as described in Section 4.2.
6.2 Cleaning
To ensure optimal performance, periodically clean the sensor's lens with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the device.
7. Troubleshooting
- Sensor not detecting motion:
- Check battery level in the app or replace the battery.
- Ensure the sensor is within range of the Zigbee Hub.
- Verify the installation height and angle for optimal coverage.
- Ensure no obstructions are blocking the sensor's field of view.
- No notifications in the app:
- Check your phone's notification settings for the Tuya Smart Life APP.
- Ensure the sensor is properly paired with the Zigbee Hub and connected to the app.
- Verify your internet connection.
- Sensor frequently triggers falsely:
- Adjust the sensor's angle or position to avoid detecting pets or moving objects like curtains.
- Consider environmental factors like direct sunlight or heat sources that might cause false triggers.
- Cannot pair the sensor:
- Ensure the Zigbee Hub is in pairing mode.
- Confirm the sensor is in its pairing mode (usually indicated by an LED).
- Move the sensor closer to the Zigbee Hub during the pairing process.
- Check if the battery is inserted correctly and has sufficient charge.
8. User Tips
While no specific user reviews or Q&A were provided, general tips for motion sensor usage include:
- Strategic Placement: Place sensors in high-traffic areas like hallways, entryways, or near valuables.
- Pet Immunity: If you have pets, try to mount the sensor at a height that allows it to detect human-sized movement while ignoring smaller animals.
- Test Regularly: Periodically test your motion sensor to ensure it's functioning correctly and communicating with your smart home system.
- Battery Monitoring: Pay attention to low battery alerts from the app to avoid service interruptions.
