This is a bit of a paradox: It sounds like several X10 "diagnostic" meters were available, but no longer are. (Due to lack of demand?) So, unless those can be found "second hand", it leaves one in the position of having to fall back to clever diagnostic uses for other "tools", or even to tedious "trial and error" (such as systematically flipping breakers and switches, and pulling plugs, etc.) So, in the absence of good meters, I'd be interested in learning of any such helpful "clever diagnostic uses" that people have developed.
Meanwhile, one area that seems like it hasn't really been addressed here is the area of tools for assessing the "health" of the electrical system itself, and for tracking-down the causes of electrical faults - such as surges, sags, spikes, and so forth. Some interesting electrical meters have been mentioned here, but it didn't look like any of those were actually fault-trackers in the sense that I'm thinking of. (Please correct me if I'm wrong about that). So, I'm curious whether anyone has found/used any good fault-trackers, that "diagnose" electrical system faults apart from X10 issues?
At the risk of "jinxing myself" by mentioning it, I'd say that - perhaps surprisingly, given the extent of my electrical system - I haven't experienced a lot of X10 "comm" problems. On the other hand, I have encountered more than what seems to be a "reasonable" number of X10 module malfunctions and failures. There is some reason to suspect that the root cause of these problems are issues arising from the electrical system itself, from either "local" or external causes - particularly some sort of spikes or surges. Consequently, I'm especially interested in tools to confirm and to efficiently track down such electrical problems. Anyone found any such good tools?
Thanks again!
