Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting to app. | Bluetooth is off; device out of range; battery low; app issue. | Ensure Bluetooth is on. Move device closer (within 20m/65.6ft without obstacles). Replace battery. Restart app/phone. |
| Inaccurate readings. | Sensor placement; extreme environmental conditions; calibration needed. | Place sensor in a stable environment away from direct sunlight, heat sources, or drafts. If persistent, check app for calibration options (if available). Note operating range limits. |
| Data not updating in app. | Phone not within range for data sync; app not running in background. | Ensure phone is within Bluetooth range of the sensor at least once daily to sync stored data. Check app permissions for background activity. |
| Battery drains quickly. | Frequent data requests; old battery. | Ensure app is not constantly polling data if not needed. Replace with a new, high-quality CR2477 battery. |
