[RELEASE] Z-Wave Universal Device Scanner <-- Here is the scanner, Get Info and Refresh both will get the version info and update the data. It does not support the wakeup from a battery device so you would need to wake it up and then press the command button within a few seconds.
If you look in the code on that, in the refresh() function it calls getRefreshCmds(), which in turn calls versionGetCmd() and sends that command out to the device.
Then the zwaveEvent(hubitat.zwave.commands.versionv2.VersionReport cmd) function catches the reply and saves it to the data.
