Troubleshooting
If you encounter issues with your DEWENWILS Low Voltage Landscape Transformer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting to smart home app | Incorrect Wi-Fi band, no Matter hub, Bluetooth off, setup timeout. | Ensure your phone and hub are on a 2.4GHz Wi-Fi network. Verify you have a Matter-certified hub. Turn on Bluetooth on your phone. Complete setup within 15 minutes; if not, reboot the transformer and try again. |
| Lights not turning on/off as scheduled | Incorrect schedule settings, network connectivity issues, power interruption. | Check your smart home app's schedule settings. Verify the transformer has power and a stable Wi-Fi connection. Reboot the transformer and router if necessary. |
| Lights are dim or flickering | Overloaded circuit, loose connections, incorrect voltage setting, long cable runs. | Ensure total wattage does not exceed 200W. Check all wiring connections for tightness. Verify the correct 12V or 14V output is selected for your lights. For longer cable runs, use the 14V output to compensate for voltage drop. |
| Voice commands not working | Incorrect device name, smart assistant not linked, network issue. | Verify the device names in your smart home app match your voice commands. Ensure your smart assistant is properly linked to your smart home account. Check network connectivity. |
