I attempted to add this comment to the "Us vs. Them" post, but it says "reply at this link" and I go to that link, and it send me back to the original. Dave Rye (to be clear, an X-10 VP) spends a lot of time stating X-10 vs Insteon, implying those are the only choices. I have a lot of high end X10 stuff in my house, but the reality is it is a dieing protocol with poor reliablity. Every time a new electronic device - from a PC down to an LED nightlight is installed, reliability goes down. It is just not practical to install a filter on every device. Nor do I know a single person with a reliabile X10 system who doesn't have numerous filters and a whole house coupler / repeater. Even most people I know with all those add-ons do not have reliable systems. I have also heard Insteon does not work well either. Here is a reponse as to why Leviton, which acknowledges X10's life is limited, choose to go with Z-wave after careful analysis -
"Long explanation, the easy answer is Z-Wave works and Insteon is glorified X-10, 120KHz burst noise at zero crossing. The RF phase coupler is kind of cool but they don’t have a mesh topology, data rates are slow and RF other than pier to pier doesn’t work. "
Smith-Corona may still be claiming the typerwriter is better than the word processor, but look at them now ...
