I see a few things in people lists that are more of a "Helper app" or "Link/translation" between types of controllers. Girder for example, as powerful as it is, is not a stand alone Home Automation software package. I am trying to weed it down to the to the primary software package.
So it looks something like this so far.........
(In Alphabetical order)
CQC
HAL
Home Control Assistant
HomeSeer 1.x
HomeSeer 2.x
MainLobby
Mister House
PowerHome
I like the suggestion to post the 2 different versions, as they are so different. It will be a bonus in the poll, on top of the main stats, to see how many made the switch ect.
Please feel free to copy this list into a reply post, and alter it as you see fit. In a few days, hopefully it will be complete enough to add in as a poll.
