I was not sure if that is the kind of screenshot you were looking for. Let me know if there is a better one that will help. I can get screen shots while at work, but can’t test fixes.
I was brainstorming last night trying to figure out what was going on, and verifying that the receiver is configured for remote access. The only thing I can come up with is the network configuration it's self. I do not have anything plugged directly into the Ethernet on Vera other than on the WAN port to connect it to my router. I figured this could explain why the uPnP does see other items, but I have not been able to control anything... I think.
Could this have anything to do with it, and is there a way to configure Vera3 to work as a hub? I did see in the documentation there was a way with other versions (Vera2 or UI4, not sure which) but those options were not available on Vera3/UI5. I tried changing the firewall to off, but that does not seem to be the same as the documented “No Firewall” which is probably what I want.
