How to add dimmer lights kaku/coco rfxcom

I thought it would be easy to add lights from kaku by rfxcom. I had domoticz and that was easy-peasy.
But now, man, I only get switches instead of dimmers.
Found some articles about via helpers, change switch to light, ok works but it is still no dimmer.
Can someone tell me how to do it? I have a lot of kaku in my house.

Hi,

Have the same issue, can not get it changed as per instructions. When auto added, change switch to light works fine (strange that you cannot select dimmer) then you need to change the eventcode, Nowhere written where this can be doneā€¦
Did you manage to change it? If so please do share how.
Thanks.
