Not from what I've seen or read, UDI has confirmed this is an issue in the past, however, it could be with openzwave and not necessarily UDI. There's an experiment I need to perform to see if i can view the ISY secure key in the other controller, I need to get around to it.
On other news, I am seeing that for every "Synchronize nodes All" that I initiate, random ghost sensors get created each time, not a lot, just a few each time. I'll have confirmation on this from another ISY sometime tomorrow, but if anyone cares to test in the meantime, that'd be cool
