I am a big X-10 fan, and would also be interested in hearing from other X-10 users, especially those with novel applications. I have a computer interface hooked up to my UNIX-PC which has an AT&T VoicePower card hooked to the phone line. I haven't done this myself, but the following is a quote from an article I saved that was posted to the net in January 1988 by Syd Weinstein. It sounds like it may be related to your problem. "I did have to solve one problem myself, but X-10 was very responsive when I called them and provided the correct values. This was when I needed to provide and rf bridge across the 2 phases of our 220 lines. My signals were not strong enough to get from one leg of the power to the other via the pole transformer. I bridged the 220 line with a 1 uF cap (value specified by X-10) and all is fine." My own disclaimer: WORKING WITH 110/220 VOLTS IS DANGEROUS. DON'T ATTEMPT THIS UNLESS YOU KNOW WHAT YOU ARE DOING. Also, don't forget that 220 Volts is the rms value - not the peak voltage. I have added sci.electronics to the newgroups, since home automation topics have been discussed there before. -- Peter Fales AT&T, Room 5B-420 N9IYJ 2000 N. Naperville Rd.
