Slightly on topic and seems to fit in with what he is asking...
Is there a wiki page that outlines the different choices available for use (z-wave, x10, etc)
Then expanding on those choices, lists what is required in order to set that brand up to connect it to the LMCE system.
Then slightly expanding on that, a list of available items (shitches\dimmers, etc) and which ones are known to work with LMCE, which have some quirks and which do not work at all?
Forgive me if i missed it, but i didnt find anything like this. What information is available seems to be scattered over several pages and makes it difficult for someone that does not know a lot to get a grasp on exactly what would be needed, etc. Im getting an idea as I go, but if this doesnt exist, it would be a good asset to newbies or those just trying to expand their current system. Ill help make something once i get to that point if it doesnt exist already.
