Still no go. Using even the default device handler (Z-Wave Switch) still locks up after frequent use. I say frequent because doing anything intensive (turn on all lights, turn off all lights, etc) reproduces the issue almost every time. Otherwise it just appears normal usage over a couple of days causes it. I removed them last night and installed a hardware GE outlet. Since the handler was already set to Z-Wave Switch and that’s the same type of handler for the GE, I was able to do a replace function without any issues. I ran 3 repairs (15 min apart) and each one completed successful.
