House automation is a gagetries dream. I bought into it years ago and have modules that seem like decades old. X10 technology started in the late 1970's they still sell it and from what I see that's all they can do is flog this 30 year old technology because it can't or wont be developed into something more. Be reminded that it seems to be the only widely deployed cheap home automation product. On the same note that it's cheap. It uses 300 Baud technology, has lag time, no confirmation of the signals that have been set out. As the old saying goes.. you get what you pay for. If you can afford it go with Zwave.. but it will cost you 100% more.
