Stanton,

There is nothing magic about a "scene" creating macro. You send "house code" "unit code" then "dim dim dim" a number of times. This works to create a sort of scene. The big difference is the cheap X10 switches have 16 dim steps from on to off, the real scene switchs have up to 200. SO when you try to create a fake scene, you get a ratcheting affect and not a smooth transition. Most of the cheap X10 switches also always go to full bright when you turn them on. Scene switches know their curent brightness level, and go from the intensity of where they are, to where you want them to be, and do it with a ramp rate that you set, they don’t need to go to full bright first. If you buy a switch between a cheap X10 and a scene switch, like the Switchlinc 2384 and use a controller that can send preset dim commands you can send direct commands to go to a specified light level but can not control ramp rate. We use these a lot with Homeseer and HAI as they can send these required commands.
