I only used products from Radio Shack and from X10.com. I believe they really should work as advertised. They don't. Given the price that SmartHome and Levitron want for simple parts, I don't see much point in throwing more money into the project just to see if they have done any better. I have been fiddling with this for several years (I recall the patch for Y2K) and it has mostly been an occasional thing. I will be replacing the switches on the garage coach lamps with a mechanical timer. The outside floods will return to ordinary wall switches. I will keep the appliance module in the garden shed, it has always worked any way. The scope interface in the App note is where one should start. It tells a lot. I have lots of electronics in the house. I don't think it unreasonable to expect the off the shelf X10 stuff to co-exist with modern electronics or at least give some indication of why not. I will continue to tinker with what I have but for now, the functional stuff is coming off line. BTW, the failure of X10 to release the CM15A specs to the Open Source folks was the last straw...
