The problems that were documented were related to the use of "relative dim" commands combined with a HCA02 repeater. "Absolute dim" commands appeared to work properly. Note that when you use the dim slider on the AHP Icons you are effectively using "relative dim" commands.
My experience with this dryer outlet plug-in repeater, was the opposite. It was the use of "absolute dim" extended commands which cause the never ending firestorm of echos for me.
Absolutely the worse X10 device I ever bought, and the only one that was so hopeless, I returned it.
