  • Regularly check the energy consumption data via the app to keep track of your electricity usage.
  • If you need to reset the kWh meter, follow the specific instructions in section 8.7. Note that some users have reported difficulty resetting kWh via the app, so the physical button method is reliable.

10. Maintenance

  • Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
  • Do not use abrasive cleaners or solvents.
  • Periodically check wiring connections for tightness and signs of wear.
  • Ensure proper ventilation around the device to prevent overheating.
  • Regularly update the Smart Life/Tuya Smart app to ensure compatibility and access to the latest features and bug fixes.

11. Troubleshooting

Problem Possible Cause / Solution
Device not powering on. Check main power supply. Ensure wiring is correct and secure.
Cannot connect to Wi-Fi / App pairing fails.
  • Ensure your phone is connected to a 2.4 GHz Wi-Fi network (5 GHz is not supported).
  • Make sure the device is in quick-flashing pairing mode (long press WIFI button for 5 seconds).
  • Check Wi-Fi signal strength at the device's location.
  • Restart your Wi-Fi router and try again.
  • Ensure the app is updated to the latest version.
Buttons (SET, Up, Down, WIFI) are unresponsive.
  • Ensure the device is powered on.
  • Try a power cycle (turn off and on the main power).
  • If only the ON/OFF button works, the device might be faulty. Contact support.
Device trips frequently.
  • Check the set protection thresholds (over-voltage, under-voltage, over-current, leakage current) in the app or on the device. They might be too sensitive for your load.
  • Investigate the connected load for actual faults (e.g., short circuits, ground faults, excessive current draw).
kWh reading cannot be reset via app. Use the physical button method described in section 8.7 to reset the kWh reading.
Incorrect model received (e.g., no Wi-Fi). Verify the model number on the device and packaging. Contact your seller for resolution if incorrect.
