I'm thinking you might be a little confused about the store - it sounds like you're buying from Automated Outlet - which is a distributor for Simply Automated, HAI, PCS, Elk, and a bunch of other products... there's no direct relationship to Simply Automated other than them being one of the products they distribute. They also sell Z-Wave and other products. Problems in your media cabinet are likely explained by the fact that AV Equipment is noisy... a noise-filtering power strip or power distribution device will often help, or filtering out the whole power strip.
yes i buy from automated outlet and they are very helpful.
but i think i am going to buy some new switches that will work with the repeater because signal strength at the repeater is like 90 with noise 5.
i have everything running in my av closet running into one outlet, which is on one breaker in the box, so i need to put a filter on that, I'm actually adding a ups this weekend so i really need to put that filter on.
I just don't understand why when I run the comm test it doesn't show much noise, maybe 5 or 6, and signal strength varies from 35-45 that noise would be the problem, but I will do what needs to be done.
