2.) The Vizia Beta firmware doesn’t do any polling on initial power-up or otherwise. That’s always been the question “Do we want to offer an option for polling?”
In a word: Yes. I'd love to move from the XZW, but the major reason for moving would be having reliable status support in the M1. Having initial and "maintenance" polling in addition to listening to ongoing status changes would be part of having reliable status.
If this will be a supported direction, I'll order up a RZC0P and another XSP tomorrow!
