My whole experience with the IoP and PG3 has been odd (putting it kindly). I had a working ISY-994>PG2. I was preparing to migrate to IoP by updating the software of the IoP. The results included breaking my ISY-994>PG2 relationship.
I thought I had, but I can see it was not obvious, or perhaps answering the wrong question. I have checked multiple times and my settings are correct as best I can tell. Both show "connected".
I was on 3.1.8, but am now on 3.1.10. It took me a few minutes to recognize that the update reset the username and password to default. This did seem to have an affect. Hue node servers are now showing connected on ISY-994 and IoP. I tried installing the Hue Emulator node server on IoP and ISY-994. No more errors and both are showing "connected". I am going to call this a small victory. The hue nodes now show up in "my lighting" , as does the hue emulator. I will call it a big victory when I can confirm or configure all the programs and scenes with the hue lights.
Usernames are correct as best I can tell. Both have been showing, and continue to show connected. Both had some node servers working but others not. But...the point may now be moot given that moving from PG3 v3.1.8 to 3.1.10 may have fixed the problem. I will know more soon, but it all seems to be coming together now
The non-standard port was driven many years ago. I had another device that also used port 80, so when I tried to access the ISY on port 80 from a remote location, it found the other device. I gave the ISY it's own port at that time and things have been working well, so I never changed it back.
I will continue to check out everything to see if it is working or, if not, update all the programs and scenes to their original configuration.
