Huh... cool. I do see the retry interval on mine, but in the "Default Message Priority" box, I only see Low, Normal, and High, with no Emergency selection. I guess I just assumed that it was Hubitat's implementation of retry, as I think "Emergency" didn't exist when I first set up pushover. I'll have to give it a test. But probably I'm just going to load up your enhanced driver for future use. Thanks for the tip!
