Im not sure who OP is, but if you meant EP, i.e. me I promise you I am not. I have had three years of hell and thought it was C4 all this time, until I found and consulted with another dealer. I'm just trying to figure out how bad this situation is and now I see. Ive spent over 100k on my smart home components and have dealt with nothing but issues and am just now figuring out what the real probelm is. Im fairly tech savvy and now realize its not me nor my equipment after getting everyones input. This has been EXTREMELY helpful and liberating. Thanks everyone.
