I guess I had two problems. The most glaring issue was I could not access locally - no lighting programs would run and I could not get to any devices at all. Thinking it might just be the computer, I had restarted windows, but to no affect. Then last night I turned it off all night and this am it came up as normal. So embarrasing, but at least I can access the ISY locally now.
So the other issue, the first issue is that I still cannot access anything remotely using the Internet and the AtHome software in Iphone Ipad. Everything was working great for 6 months or so, and I did not make any changes. It just stopped working. From the Ipad it says locating host, but times out before it get anywhere.
All my connections look good, have stopped and started the ISY, the connection to the router, and the connection from the ISY to the wall power module that communicates with the rest of the devices. I have tried updating the software as well. Its just not communicating. I'm not sure how to debug it, not even sure if its hardware or software.
Thanks for your help
I am not schooled in the details of how the software communicates, so I'm shooting in the dark to figure it out.
