Control RGB Lights with IOT Adapter and Alexa

[Ikswoknib]

Hello,
is it possible to get RGB Lights to work with the IOT Adapter ?
When i try to add a device in the IOT Adapter, I always get the message that it is not possible when i try to use one of the two colorTemperatures or the level. I can only add the single colors to the IOT Adapter.
I had read in another Forum that it is possible for example for deconz Devices to add lights as a rgb Device...
So is it possible with the loxone adapter ?

Thanks and best regards

Christian
