I own a few dozen X10 modules that will eventually be phased out mostly. I see a chart on the ISY page that gives differences between these two models s 300 vs. 1000 devices, and 300 vs.1000 programmes. I feel 300 devices would probably not be a problem for a home user, like me. Is there a significance to the 300 programme limit? Is there other significant differences? Hardware? Upgradebility? CPU speed? What about the X10 module? Is this included or required in either model? What is it needed for? Is there somewhere that explains this? Thanks in advance.
