I agree Stefan - the CEN+ functionality really requires rules for it to be useful. I think having it as a Switch would be too restrictive. The best would be to have single commands that can be attributed to the various button presses.
Massi I don’t understand what you mean by having “no_action”. According to the Openwebnet documentation these are the types of press:
Virtual short pressure (<0.5sec) *25*21
Virtual start of extended pressure (>=0.5sec) *25*22
Virtual extended pressure *25*23
Virtual release after extended pressure *25*24
In practice this means either a short or a long press
If you want to do some dimming or volume changing then picking up the Virtual extended pressure frame would be useful.
I’m not sure of a used case for the Virtual release after exended pressure?
