Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No outdoor temperature/humidity reading. | Sensor out of range, low sensor battery, interference, or sensor malfunction. | Ensure sensor is within 200ft/60m of the main unit. Replace sensor batteries. Relocate units to avoid interference. If issue persists, sensor may be faulty. |
| Inaccurate humidity readings. | Unit not stabilized, poor ventilation, or sensor exposure to moisture. | Allow several hours for readings to stabilize after setup. Ensure proper air circulation around sensors. Protect outdoor sensor from direct rain. |
| Inaccurate temperature readings. | Unit not stabilized, direct sunlight exposure, or proximity to heat/cold sources. | Allow several hours for readings to stabilize. Place units away from direct sunlight, heating vents, or air conditioners. |
| Display is dim or blank. | Low main unit battery or USB power disconnected. | Replace main unit batteries or ensure USB cable is securely connected to a power source. |
