I found that firmware updates for Inovelli devices are only working for me using the Z-Wave FirmWare Updater and that requires items to have no security. (I cannot get anything to update using the built in Device Firmware Updater). I'm also having issues with the hub becoming non-responsive and it was suggested I remove all security for all my devices.
When I went to exclude one of my Inovelli Fan+Light, LZW36 switches it wouldn't do it. I got the flashing blue LED when I held button A and tapped button B 3 times, but it was never excluded. I then went into the device and did a Force Exclude, which did make the device go away. I was unable to get it to be re-included, even though I got the same flashing blue LED when I held button A and tapped button B 3 times. I didn't have any trouble including it when I originally did it, and the range test (holding buttons A and B for 5 seconds) gave me a solid green light.
I then rebooted the hub. This time inclusion worked, but it skipped past the part where it asked for the DSK # and Security level. So it was included again with S2. BTW, this device is not being used by any Hubitat rule or an association, so I know those aren't creating any issues.
I'm 1/2 afraid to go through this again in case it doesn't re-include. But if I was to do so, what do I have to do to set it to ask me for the security level?
