Okay,

So running the current version of Vera (1.7.4001), I have successfully added my first Aotec Wallmote Quad to the home z-wave network.

What is the best way to link groups of lights to a particular button (on, off, and dim)?  Note these particular lights are Philip's Hue connected.

Hopefully you have figured this out by now, but what I did was created a Scene for each button, such as

"All Lounge Lights on" and
"All Lounge lights off"

Then I added that scene to the Button.
For example  Button 1.
Single Click, run Scene "All Lounge Lights on"
Double Click run Scene "All Lounge Lights off"

It feels a bit messy and you end up with bundles of scenes if you have a few switches but it works.
