Set Color for white LEDs in RGBW strips


#1

1) Give a description of the problem
I’ve got RGBW strips connected to GLEDOPTO controllers. It’s working fine, and in ST I can set colors, or set the color temp. When I set the color temp to cool white, the RGB LEDs turn off, and I get the white LEDs.
I’ve created a piston to flash a color when there’s motion at the front door. It works, but when the flashing is over, and I set the color to “cool white”, it’s using the RGB LEDs instead of the white channel on the controller.

2) What is the expected behaviour?
When I set color to white, it should use the white LED channel of the RGBWC controller.

3) What is happening/not happening?
It makes “white” with the RGB LED channels instead of the white channel

When setting “set color”, which color would disable the RGB channels, and trigger the white channel?
Or am I going about this in the wrong way? I’m pretty new to this.

I figured this out through trial and error.

Using “Set color temperature” controls the warm and cold white channels on this controller. So instead of setting the color to cold white, you have to set the color temperature to 6500k. It turns off the RGB channels and uses the cold white channel. I would assume that it’s the same for the warm white channel if set to 2700k. Anything in between 2700 and 6500 is probably mixing WW and CW, but I haven’t checked as I’m using RGBW strips.

Can you post your piston?
