⚡ Easy DIY Troubleshooting & Common Fixes

🔧
Sensor stops detecting presence after a few minutes of inactivity, even with people in the room.
prob_01
Common root cause: Automation app 'stay' time setting is too short, or the sensor entered power-saving mode.
Step-by-step solution: Check automation settings for the sensor in your smart home app and increase the 'stay' time or disable power-saving modes if available. Consult your gateway or app manual for sensitivity and detection time options.
💡 Pro tip: Set the 'stay' time to a reasonable value (e.g., 1-2 minutes) to avoid false timeouts in low-activity areas.

🚫 What NEVER to Do (Common Misuse Warnings)

⚠️ Installing the sensor directly facing heat sources or rapid movement (air conditioners, heaters, curtains in wind).
err_01
Consequence: Constant false positives, indicating presence when no one is there, or unstable detection.
✓ How to avoid: Position the sensor away from heat sources, direct drafts, and avoid pointing it at areas with non-human movement.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How do I integrate the sensor with Home Assistant if my gateway is Tuya? cfg_01
Direct integration with Home Assistant may require a Zigbee gateway compatible with ZHA or Zigbee2MQTT. If using the Tuya ecosystem, the most common integration is via the Tuya cloud (requires prior setup in the Tuya/Smart Life app and subsequent addition via the Tuya integration in Home Assistant), which may have latency and cloud dependency limitations.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty activation is indicated when the sensor exhibits operational failures that cannot be resolved with the self-resolution procedures described, such as complete failure after a short period of use, persistent Zigbee connection issues that do not improve with gateway proximity, or completely inconsistent detection even after adjustments and repositioning. These scenarios may indicate a manufacturing defect.
