Colors with Fibaro RGBW module

[OlivierFR]

Hello,
I have a Fibaro RGBW module FGRGB-101 connected to a RGBW LED strip.
Using the color picker control in Domoticz, I can set the color by mixing the RED, GREEN and BLUE leds.
When I choose a very light color, it turns off teh REG, GREEN and BLUE leds and turns on only the WHITE led.
However it never mixes the R, G and B leds with the WHITE led, to create pastel colors.
This is typically the added benefit of a RGBW led strip versus a regular RGB strip.

Is there a way to do this in Domoticz? Should the color picker control also include a sort of dimmer for the WHITE led in order to mix all 4 leds?

Thanks for your help,
Regards,
Olivier

Did you ever find a solution for this? I have the same problem.

Im also haveing problems with this device

The color picker looks like a run-of-the-mill rgb picker, and technically it shouldn't trigger the white led at all. I think I do understand what you're after though. But I think your suggestion would mean that every time you pick a color you would also have to alter the white-level (unless the white-level already is set to what you think matches your newly selected color).

That was tougher than I thought to explain, I hope it made some sense..

Wouldn't it just be easier using the seperate sliders to select a color, or (pretty close to your question) set color using the color picker and then set the white-led using the dedicated device-slider for the white channel? (might even be doable in a script or that lego-thingamabob.... erm... blockly?)

(I have the FGRGBWM-441, but I think its the same hardware....)

I think you are right but I have no clue how to make that...

Same Problem here.

Does anyone know if it is possible to set the values of the different channels from LUA?

I have the same issue. I imagine this is because the RGBW implementation is based on limitless led and those bulbs are incapable of turning on white at the same time as colours (although their new bulbs have this feature so I suspect this is going to become a popular request). Did anyone solve this using Lua or any other code? As soon as the new limitless bridge comes out I intend to order a lot of new bulbs so keen to find a solution.

I am also looking for a way to control colors of the rgbw module via lua or api. It would be cool to set a random determined color or Hue.
I can find hue settings for the lamp in the scenes table but not in the devices table, so i am clueless about how I could control this programmatically.

So anyone with a solution?

I managed to control color with api f.i.

I have the Zipato RGBW Bulb. Same issue, it's never really worked properly. So I'm not using it on a daily basis, and usually after upgrading domoticz to a newer version I notice some difference in behaviour, if I happen to test it. I believe this light even has two white leds: warm and cold.

You should be able to use the single dimmer devices of the fibaro module to set any color in LUA (in %):

commandArray['$RGBW1 R']='Set Level '..levelR
commandArray['$RGBW1 G']='Set Level '..levelG
commandArray['$RGBW1 B']='Set Level '..levelB
commandArray['$RGBW1 W']='Set Level '..levelW

Would that be possible in Domoticz:
- Create a virtual switch that is associated with a LUA script , type dimmer
- Invoke the color picker like for the rgbw dimmer
- Interpret the returned color value in my way and set the levels accordingly

Currently, I'm doing sufficiently well with this procedure for my FIBARO FGRGBWM441 RGBW Controller:
- Choose RGB color with the picker (overrides RGBW values)
- Choose White level with slider (adds white)
- Adjust brightness with "Bright RGB" slider (affects all 4 RGBW values)

However, having one central HSV picker would be the right thing.
