GRBW issue on white led not working

[Adrien]

Hello.
I looked for it in the other topics but I'm not sure it was solved.

I've a SK6812 RGBW from BFT Lighting which is working well. I setted up the LED model on GRBW and everything is working (all my 60 leds on a 1m strip and all the effects) but the white leds.
RGB are lighting but the white one is still off.

I don't know if there is a specific way to send it with the web interface, I tried "rgb(255,255,255)" but still not working.
Am I doing it wrong or is there a bug ?

Thank you for your answer

The only preset color for RGBW LEDs is ULTRAWHITE.

Try the ws2812fx_segments example sketch with this:

ws2812fx.setSegment(0,  0,  LED_COUNT-1, FX_MODE_STATIC, ULTRAWHITE, 1000, false);

That should at least show you that your white LEDs are working.

Beyond that, the web interface sketches in the examples folder do not support RGBW LEDs, because the HTML color picker doesn't support a separate white channel. You would have to write your own.
