7. Troubleshooting
If the device is not functioning as expected, consider the following troubleshooting steps:
- No Display/Power: Check the main power supply and all electrical connections for proper installation and tightness.
- Wi-Fi Connection Issues: Ensure the device is within range of your Wi-Fi router. Verify your Wi-Fi network is stable and the password entered in the app is correct. Try restarting your router and the KWS-302WF device.
- Unexpected Power Off: Review the protection settings (over-voltage, under-voltage, over-current, overload, overtemperature) in the device or app. The device may be triggering a protection mechanism due to parameters exceeding set limits. Adjust thresholds if necessary and safe to do so.
- App Not Responding: Ensure your Smart Life or Tuya app is updated to the latest version. Try force-closing and reopening the app. If the issue persists, unpair and re-pair the device with the app.
- Inaccurate Readings: Verify that the wiring connections are correct and secure.
- General Malfunction: A power cycle (turning off and on the main power to the device) can often resolve minor software glitches.
