I am glad that someone is using the plugin
No I have not considered to make the Vera's scenes available within the plugin (at least not until yesterday).
I wanted to have the possibility to make Vera behave differently depending on if for example I am at home or if I am away, so that is why I wrote squeezedVeraScenes in which you can pick different scenes like that. At least in the beginning it was not possible to do that within Vera.
Then I wanted to use my Squeexebox as a convinient UI for controlling which scene should be active. Through the Squeezebox I also wanted to be able to trigger different scenarios, like turn off all lights in my home when I go to bed.
What additional benefits do you think that using Vera's scenes in the plugin would bring, compared to using scripts like it is done today?
