How to handle ZigBee Gledopto RGB-CCT Controller

---

Hello Community,

I bought such a controller: https://www.ebay.de/itm/RGB-CCT-RGBW-WW-CW-Steuergerät-Controller-ZigBee-kompatibel-LED-Lichtband-12-24V/123410333065

I connected a RGB Stripe and a 12V LED spot to the controller.

Via Phoscon/DeconZ I’m able to control the different channels.

RGB is controlled via Color, Brightness and Saturation.
CCT is controlled via Brightness and WhiteLevel (warm/cold).

How could I switch the different channels in pimatic?
The device is paired as a RaspBeeRGB device.

I want to have something like:

when button1 is pressed then turn controller-rgb on
when button2 is pressed then turn controller-cct on
when bla then dim controller-rgb to xx%
when blub then dim controller-cct to yy%

Setting color to #abcdef and dim level to 70 turns the stripe on and automatically the spot off.

Setting color temp to 100 turns the spot on and automatically turns the stripe off.

This would be okay for me. But I don’t see a chance to turn both off.

dim to 0 let’s the stripe still glow in dark red
