WLED xLights RGBW - Need some help

[fvierra27]

Hello all,

So this year for Christmas I decided to put up some "permanent" lights for year round holidays. I went off the beaten and ordered 1000 SM16704 12mm 5V RGBW lights. Tested them with WLED and everything looked good. With plans to slowly add every year and make a "show", I started looking at xLights.

Got an XATW loaded up selected RGBW Nodes and something isn't right. I can get it to play in sequence if I select RGB nodes but the white lights up both the white and the RGB (making white). I know little to nothing about LEDs besides what I am trying to pick up on the fly. Any clues on how I can try to get this squared away? Or am I just SOL? Was looking to pickup a controller to replace my two Dig-Uno WLED boards but I feel like I shot myself in the foot trying to get RGBW.

I have tried looking for documentation on the RGBW Color Handling Options but I couldn't find anything. It's weird that WLED knows what to do with the White Channel but xLights doesn't. Anyways, thanks for the help!

Well tell us when is the right time to fire the W channels?

Currently I believe it turns on W when you specify any greyscale color otherwise you get the RGB channels.  So greyscale to us means the R G and B values are equal like 100, 100, 100 or 255, 255, 255.

So it looks like when I used WLED with RGBW selected it does the white channel mixing itself. I managed to hack together a small set of strings to test in the office. I think I got it to behave the way I want by using the white channel option in WLED and RGB Nodes in xLights. There are "Auto-Calculate" settings in WLED that I messed with and changing it to "accurate" made the difference.
