Finally decided to ditch the old X10 system after 10+ years of reasonable use. Purchased the VeraLite, 20 plugin dim-able modules, a couple of wall switches to get myself started on the conversion. 12 of the plugin modules will be used for the 12 electric candles that are located in all the front windows of our colonial home. With my old X10 system all I had to do was assign the same code to all of the window candle modules and could then control ALL of them as one. I have no need to control each window cancel separately, they all go on at sunset, dim at 11pm, and go off at sunrise as a group. I want to replicate that action in my new Z-Wave, VeraLite environment. I’ thinking that I need to let each module exist alone and use a scene to accomplish the group on/dim/off I need. But looking at the advanced device settings I see several setting that suggest I may be able to “group” these 12 modules together. Any help on this would be awesome.
Vera doesn’t have a group these devices as a single device concept. But, a scene would provide the functionality that you desire.
There are hardware “scene” controllers and in-wall switches that can do something called an association. This hardware scene is nothing like nor is it in anyway related to Vera scenes. A Hardware scene is a grouping of devices, where as a Vera scene is a script of actions.
When a scene capable Z-Wave device is associated with other devices, activating the primary device will cause the others to respond in kind. These associated devices need to be uniquely identified within the switch as some hardware scene controllers could have multiple association groups.
The Vera UI can create/program these hardware scenes into the contollers. Perhaps unfortunately, each hardware scene is referred to as a group ID.
As if all this wasn’t ambiguous and confusing enough, there is one last detail you may want to be aware of. Each hardware scene(group) is unique within the scene controller device(switch). No other devices are aware of or use it in any way. For this reason, the group ID are reused.
As an example, lets say that Switch/scene controller A and B have other light switches assigned to them. Switch A has switch one, two, and three assigned in a hardware scene(group). The Group ID is 1. Switch/scene controller B has switches four, and five assigned to it in a hardware scene(group). The Group ID is also 1. But the group IDs exist only inside the switch, the group IDs are not related or connected at all even though they have the same number.
Activating Switch A simultaneously turns on switch one, two, and three. Activating switch B turns on switch four and five.
"I have no need to control each window cancel separately, they all go on at sunset, dim at 11pm, and go off at sunrise as a group. I want to replicate that action in my new Z-Wave, VeraLite environment. "
This can be readily accomplished through a scene (or scenes). I’m sure plenty of folks here are willing to help you out if need be.
I also came from an X-10 background and did the same type of thing (give multiple modules the same address) for Christmas lights. With your new Z-wave modules, you won’t have to worry as much about “using up all of your addresses”, so it’s okay for each module to be unique.
Going from X-10 to Z-wave can create some sticker-shock, and in a case like yours I might have considered plugging two or more (assuming low wattage) electric candles into one module. It would obviously depend on how close the windows are to each other, and what the cord situation would end up looking like. Since you already pulled the trigger, I would take advantage of the situation and try a little more elaborate scene.
Through the use of delayed Device Actions, you could reasonably simulate the appearance of somebody walking through the house, sequentially lighting each candle. It’s a subtle thing, and would probably take a while for folks to notice what’s going on. But when they do, you’d be the envy of the other colonial houses on your block. 
Thanks guys, that was the answer I expected. And I really like the idea of a scene that turns on the 12 candles in a sequence emulating someone walking from window to window, very cool.
