My Thanks to both Getty and Mr. Bill!!!!
SUCCESS
I was able to wade through all your information and install firmware 5.3.4.
It was not easy to understand and much of the information did not apply (I hope). It would really be a boon to Universal Devices to hire a documentation expert to clean up all the instructions etc. Some of your customers like me do not work on our ISY every day. I had not upgraded my system in several years. I have written a few new programs in the last year, but even that is hard to pick up when you haven't used it for a while. I know I am speaking with experts and it is hard for you to know what I do not know. Example: When you told me I should back up my programs to text by copying the folders and pasting them in a text editor I tried to do exactly what you said and it failed. I finally figured out that I needed to use the "export to clipboard" option instead of copy to clipboard. (The information exported was in hypertext so I am not sure what use it would have been to me... unexplained). There was a lot of information that could have been better imparted through an old fashion decision logic table. If you have this, then do this, then return to here and continue. For example there were different versions of the software to download. I am not familiar with Z-Wave and many other topics so how do I know whether I have it or need an upgrade version with it?
It is nice that a user forum exists, but it is like searching for the holy grail buried on a beach somewhere in the world. Once a problem has a verified good answer in the forum the information should be cleaned up and placed in the official documentation so hundreds of people are not tripping over the same rock in the path to the information they need.
Now on to my next search for information. How to set up the UD Mobile app with accounts for unsophisticated users that should have the ability to do simple tasks (like dim a light) without mucking up the entire ISY. Are the users programmed into the ISY the same ones programmed into the app. I doubt it. But I haven't a clue, and I am not sure I want to invest all the time to find out.
Sincere Thanks,
Hopefully someone will read this and get a clue. OR... give me better clues.
