> I looked into home automation when I had to work on an old house. I looked into KNX, which seemed to be a good standard: adopted by several manufacturers, robust, etc... The biggest problem, beside the price, is that I can't buy the hardware I want (ex: A/C unit) and expect it to connect to my network. You could integrate KNX into IP, but that would require another server which is either dreadfully expensive, or just way to complex to maintain for an average house. Also, i don't know how it is in the US, but many buildings around my area lack any proper cabling infrastructure because they are ancient. Things like having cable gutters for ethernet and coaxial connections. Most have a single coaxial cable coming in from the floor directly into the living room. (because that is where the TV/radio used to be). These buildings are unlikely to be broken down because of their high value, but renovating them would cost a fortune. Currently no proper standard for wireless home automation exists.
