Read 4 bit dimming command from KNX bus

[Dim (Angelos)]

Ok… Personally, I don’t have experience with the -control type of Channels in KNX.
@Udo_Hartmann has used them and he maybe able to help you.

You can try to use a rule that takes the input from the KNX bound Item and sends it to the Z-Wave Dimmer.

To be honest, it’s not 100% clear to me either the -control functionality and the documentation entry is a bit vague:

Control Channel Types
In contrast to the standard channels above, the control channel types are used for cases where the KNX bus does not own the physical state of a device. This could be the case if e.g. a lamp from another binding should be controlled by a KNX wall switch

We need to develop some examples to add them in the documentation. Maybe an example with a Dimmer Item that is bound to 2 binding configs would be useful.
