7. Troubleshooting
If you encounter issues with your PopBloom RL90 WiFi Reef LED Light, refer to the following common troubleshooting steps:
- Light Not Turning On:
- Check if the power supply is securely connected to both the light unit and the power outlet.
- Verify that the power outlet is functional.
- Ensure the light is not set to an "off" period in the app schedule.
- WiFi Connection Issues:
- Confirm your home WiFi network is 2.4GHz. The device may not connect to 5GHz networks.
- Ensure your smartphone is connected to the same 2.4GHz WiFi network during the setup process.
- Restart your router, the light unit, and your smartphone, then attempt to reconnect.
- Make sure the light unit is within range of your WiFi router. Consider a WiFi booster if range is an issue.
- Light Schedule Not Working / Light Stays On:
- The light schedule is managed through the app. If the app is not actively running or connected, the light may revert to its last manual setting. For continuous scheduling, ensure the app or a dedicated device (e.g., an old smartphone) maintains a connection to the light.
- Verify that the schedule is correctly configured and saved within the app.
- Flickering or Malfunctioning Light:
- Check all cable connections for looseness.
- If a specific channel or feature (e.g., lunar light) is not working, try resetting the light unit (refer to app for reset options or power cycle).
- If issues persist, contact customer support.
- Fan Noise:
- Ensure the fan vents are clear of dust or debris.
