Good evening @datavortex – sorry for the frustration here 
The dimmer and aux switch should work if you have an ilumin bulb paired as @rbf suggested above via Z-Wave Association.
However, since you’re using a Hue bulb, as you correctly setup, you’ll have to use scene control. The unfortunate thing about this is that the auxiliary switches will not provide scene control (ie: double/triple tap, etc) as noted in the following threads:
I do, however, see the miscommunication in the KB Article and I will clarify it to prevent further frustration. That article was written for a single-pole setups, but I will go back to clarify this in the KB Article.
The good news is that we are about to submit a request to the manufacturer for the alternate version of firmware that hopefully they can figure out the multi-tap (scene) control from the aux switch. More to come here – we’re just trying to get the normal dimmer firmware completed.
Sorry again for the frustration.
