8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting to app | Bluetooth is off; device out of range; low battery; app issue. | Ensure Bluetooth is enabled. Move device closer to smartphone. Replace batteries. Restart app or smartphone. |
| Inaccurate readings | Device not acclimated; sensor obstruction; proximity to heat/cold source. | Allow 30-60 minutes for acclimation after moving. Ensure sensors are clear. Place device away from direct heat/cold sources. |
| Missing data points in graph | Device was out of Bluetooth range for extended periods; batteries removed. | Ensure consistent Bluetooth connection for continuous data logging. Data recorded while batteries are removed will show as blank. |
| Short Bluetooth range | Obstructions (walls, metal); device placed inside insulated containers (refrigerator, cooler). | Minimize obstructions between device and smartphone. Bluetooth range is significantly reduced in enclosed or insulated spaces. |
| Device not turning on | Dead batteries; incorrect battery installation. | Replace batteries. Check battery polarity. |
