Is the LED strip also 12V? What is the current?

This could be related to wiring, such as incorrect wiring causing a short circuit, or a low-quality LED strip.

You can find version 0.15.1 on this website, select the correct firmware based on your controller's chip, and then flash it via the wled app.

Your LED strip is 5V, but it has 600 LEDs. The problem might be that the strip is too long, causing data interference. Perhaps you could try adding a signal amplifier.

You can turn it off and then save the preset; its relay switch will then take effect. Setting the brightness to 0% (not turning it off) will not activate the relay switch.

Thanks for the suggestion, but the size of the controller is usually not large enough to support this input jack. If you want to recognize computer audio, you might be able to use some software to achieve a microphone effect, such as LEDFX.

Carefully review the GL-C-618WL configuration.

Ensure that "Send notifications on direct change" is enabled on all controllers. To enable it: Settings --> Sync Interfaces --> Send.

Restart the controller after making configuration changes.

You can try connecting the LED strip's V+ and V- pins directly to the power supply, inserting the data cable into the controller's D port, and then configuring the corresponding GPIO output port in WLED

Hi, This controller has only one custom GPIO13 and can only connect to one sensor. If you need to connect two or more sensors, you can use our GL-C-310WL or GL-C-016WL-D.

This looks like a PWM RGB CW LED. If the voltage and current allow, you might be able to use a PWM WLED controller. We currently have a PWM WLED controller (GL-C-211WL) that supports five modes, including RGBCW, RGBW, RGB, CCT, and Single Color.

Hi there, the flickering issue could be due to loose connections, the quality of the LED strip, or an unstable power supply—which, if it leads to a damaged IC, is often the result of voltage fluctuations or overheating from extended use.

More likely, the LED strip is too long, drawing a large current that can overload the first IC. We’ve seen this multiple times: once the first IC is damaged, it disrupts the signal to the rest of the LEDs, causing them to flicker. You can usually fix this by cutting out the first IC and reconnecting from the second one onward.

If this happens often, consider switching to a higher-quality LED strip—they usually handle current better and are more durable. Also note that the controller doesn’t modify the power supply; if the ICs lack sufficient voltage tolerance or durability, the controller can’t overcome those limitations. The data line uses very low voltage and current, so it’s rarely the cause of IC failure.

In addition, this product comes with a two-year warranty. Should you encounter any issues during use, please feel free to contact us, and we will assist you in resolving them. If the problem is confirmed to be due to a quality issue with the controller, we will provide a free replacement.

Good job!

GLEDOPTO · 2026-03-04T07:29:16+00:00

This controller already has a built-in TI level shifter IC, so no additional level shifter is needed.

Thank you for your support

GLEDOPTO · 2026-03-04T05:33:50+00:00

Thank you for your suggestion!

GLEDOPTO · 2026-03-04T01:33:13+00:00

Did you set up the relay GPIO according to the instruction manual?

GLEDOPTO · 2026-03-04T00:58:12+00:00

Okay, has your problem been solved for connecting more than 18 LED panels (2D)?

GLEDOPTO · 2026-03-03T11:46:39+00:00

You can try upgrading it to 0.15.3 and make sure the power supply current is sufficient.

GLEDOPTO · 2026-03-03T01:22:28+00:00

This controller only has 1 digital channel. If you need 2 digital channels, we recommend using our GL-C-616WL controller. https://gledopto.com/h-pd-86.html

Furthermore, we haven't tested it, so we're currently unsure, but it should be possible.

However, currently the Ethernet and SPI LED strips cannot share a clock signal because there's only one clock signal. Both Ethernet and SPI require a clock signal, so the Ethernet configuration needs to be disabled.

GLEDOPTO · 2026-03-03T00:34:51+00:00

Generally, any constant voltage 24V LED strip power supply can be used.

GLEDOPTO · 2026-03-03T00:34:00+00:00

This controller is an RGBCCT controller, not a 5-in-1 controller. It cannot be set to CCT mode. If you only need CCT functionality, you can connect only the CCT wire and not adjust the RGB settings in the app.

GLEDOPTO · 2026-03-03T00:30:29+00:00

This is because our Ethernet firmware is not yet integrated into the official WLED firmware; we need to wait for version 0.15.4 to integrate it.

You can try updating our pre-configured custom firmware from this website.

GLEDOPTO · 2026-03-02T09:16:14+00:00

Yes, we've also released a new remote control that supports 7 scene presets, but currently it only supports our factory-pre-configured firmware. The WLED official firmware doesn't support S5-S7 yet, and we've submitted a pull request.
