So it is possible to reset an Insteon interface thru the GUI, I don't see a way to do that with the Z-Wave interface. And try as I might, I occasionally get stuff looping endlessly, and it always seems to happen when I'm not at home. Clearly the "fix" is to find what causes my looping action and change it, but thats almost impossible to do from my phone when away from home.
Even a python script to disable the Z-Wave interface, and then re-enable it a few seconds later would be a huge help.
