color picker widget (aCKolor) works only in rgb mode

[ArekHas]

The color picker output is in rgb (r,g,b) the hue implementation in iobroker accept xy oder three single inputs for rgb.

Is it possible to extend the color picker to xy output? Im not sure if its better to implement a new output here or in the openhab.ui.panel branch, but the xy output is only needed for iobroker inplementation.

enclosed a possible rgb to xy convert

regards arek

Hello all,

Has anyone here already found a solution in Iobroker to control hue lights via the HubPanel? @ChR-iSz you said you working on something. Can you share your knowledge?

Hi @Kiko1432,

I must look into my past code for this. Currently i dont use iobroker, but let me check tomorrow my old workaround.

Cheers chrisz
