I hoped it would be here to stay, Jim. My house uses X10 automation, and for now there's little reason to spend a lot of money changing that. But I did intend to go to Z-Wave when I am earning some money again. For now iRule is doing a great job of controlling it all, and it does Z-Wave too, but I was planning to buy Engen when ready. I could do so very soon if it would help, but I know it would take hundreds like me, probably.
