Try http://www.x10-beta.com/ActiveHome/ (CM11A) There are lots of cool X-10 devices available. Apparently the patent expired. I got a computer interface from Radio Shack for $30 that I highly recommend (send and receive) ( model CM11A) Gus Hiya, This is Naresh from Singapore. I just like to know if anyone can help me with sending X-10 signals on a 110\VAC line (or 220VAC line) to interface with a PIC microcontroller. What I'd like to do is simply switch on and off a pin, but it has to have a device identity (i.e. able to distinguish upto 256 devices). Cheers!
