The firmware update file is the same. What you need is a way to perform the update, as Hubitat's Device Firmware Updater app does not work on the C-5 or earlier. There is a "community" firmware update driver that should work for this. You need the "binary" version for this update (I think--assuming the update is a .GBL or similar format), which can be found in this post: [RELEASE] Z-Wave Firmware Updater - #860 by bcopeland
I didn't do extensive testing with combinations of commands, just verified that each alone with various parameters I tried appeared to work as expected. I assume you mean a bug in the device firmware? I can't imagine anything the driver could be doing that would cause that. Again, you may want to reach out to Zooz to report this. (I don't have easy access to a real device except on weekends, so I'm unable to test this myself now...)
