The KeepSmile app and LED light products allow you to easily control your lighting from your smartphone via Bluetooth. However, some users have reported issues with the app not working properly or the LED lights malfunctioning. Here are some common problems and solutions to get your KeepSmile system up and running smoothly again.


App Connection Issues

One of the most frequent complaints is the KeepSmile app failing to connect to the LED lights. If you open the app and it gets stuck on the login screen, won’t recognize your lights, or gives a “network unstable” error, try these fixes:

  • Check Bluetooth: Make sure Bluetooth is enabled on your phone and the KeepSmile device. The app requires a Bluetooth connection to control the lights.
  • Restart the App: Force quit the KeepSmile app and relaunch it. This can resolve minor software glitches.
  • Reinstall the App: If restarting doesn’t help, uninstall the KeepSmile app from your phone. Download the latest version from the app store and reinstall it.
  • Reset Lights: If your lights still won’t connect, reset them. Unplug the power supply, wait 10 seconds, then plug it back in. This resets the Bluetooth connection.

LED Light Problems

Another common issue is the LED lights themselves not working properly. Sections of the strip may be unlit, display the wrong colors, or not turn on at all. Here are some things to check:

Lights Won’t Turn On

  • Check Power Supply: Make sure the power adapter is plugged in securely and providing the correct voltage for your lights (usually 12V or 24V). Try a different outlet.
  • Check Connections: Inspect the wiring between the power supply and LED strips. Make sure all connections are tight and no wires are frayed or damaged.
  • Test Strips: Plug the LED strips in without connecting them to each other. If one works but the other stays off, that strip may be defective and need to be replaced.

Wrong Colors Displayed

  • Check Wiring: Make sure the red, green, blue and white wires on the strips are connected to the correct ports on the controller. If swapped, colors will be incorrect.
  • Inspect LEDs: Look closely at each section of the strip. If one small segment shows the wrong color, that means some LEDs are damaged in that section. You’ll need to replace that part of the strip.
  • Update Firmware: Connect the KeepSmile controller to the app and check if a firmware update is available. Install any updates, as they often include bug fixes.

Only Half the Strip Works

  • Test Connections: The strip may have a loose or faulty connection in the middle. Try gently pressing on the LEDs and see if the rest of the strip comes on. If so, you’ll need to reattach the strip connectors or solder the connection.
  • Check for Overheating: If part of the strip stays off, those sections may be damaged from overheating. This is more common on older or lower quality strips. The heat-damaged sections will need to be replaced.

Other Solutions

Avoid Counterfeit Strips

Make sure you are using authentic KeepSmile LED strips. Fake or knock-off versions often have connection and color issues.

Don’t Exceed Max Run Length

Pay attention to the maximum run length listed for your specific KeepSmile strips (usually 10 meters). Exceeding this can cause voltage drop and connectivity problems.

Use a Surge Protector

To protect the strips and controller from power spikes and surges, plug the power supply into a surge protector device.

The Bottom Line

By methodically checking and fixing each component of your KeepSmile LED system, you can usually identify and resolve any issues with the app or lights not working properly.

Check connections, wiring and power supply first, as these are the most common culprits. If all else fails, contact KeepSmile customer support for further assistance or warranty claims on defective products.

With some patience and persistence, you’ll soon have your KeepSmile lights shining bright and dancing to your smartphone’s commands once again. Enjoy your colorfulcustomized lighting experience.
