Hi Eric, 
Looks great, but how did you get the sliders to work?  I can control various scenes via on/off and brighten / dim commands but the sliders and brightness feedback displays don't work for me no matter what I put in the "Node:" field.  For what it's worth, I'm using the new Simple Control version on my ipad mini. 
  
I'm a relative novice to both Roomie and my ISY994i but I was able to generate the topology and get the node info for all of my devices.  I'm just unable to figure out how to use that information properly with Roomie.
