I managed to use the colorpicker (dummy) with my mysensors moodlight.

I used rules to transmit the dummy variables to the moodlight. But it would be easier to integrate this into mysensors. But pimatic-led-light supports more than this, like temperature colors, colors by name etc.
Is there a way to combine those 2 plugins?
