My ISY worked fine for about a year, then a few months ago started turning lights on randomly.  Sometimes it would occur soon after turning off a light manually (turn itself back on several minutes later), sometimes completely random, wake up and have 3 lights on. 
  
I unplugged it for a few months, then recently had time to try to trouble shoot, i updated its software, and it seems to be a *little* better, but still getting random on's and still get it turning lights back on soon after i turn them on.   
  
There is also an ELK involved, but that seems to be functioning fine. 
  
Anybody seen this (and i do not believe it is any of the insteon devices as they all work properly when the ISY is unplugged). 
  
Thanks!
