Hi everyone,

I bought this LED lamp at Aldi and I’m trying to control it with WLED. So far, everything works fine except for the white LEDs — I can control the RGB colors, but the white light doesn’t turn on.

I suspect that the white channel is controlled through the 4th pin (W-), but I’m not sure how I can configure this in WLED.

At the moment, I’m using the **WS281X RGB** LED strip profile.

Does anyone know how I can configure WLED to control the separate white channel as well?

Any help would be greatly appreciated. Thanks!

Looks like ARGB plus PWM white.
