As I looked through the threads on this forum, I saw numerous posts from UDI folks that only one portal existed. What may have been changed in ISY since those posts were made is something I don't know.
When I use the drop down menu, I get the message that ISY is not on-line. When I look at the "About" drop down, it shows the portal is being used by Mobilinc.
I'm not a computer guy, so figuring this stuff out requires I take the most simple and direct route possible.
