I am thinking it is version 1.1 (or shown as 1.01 depending on formatting) in the firmware file. The .0.9 is an extended version they are tracking. Not sure why the heck they would do that, makes it so you have no idea what version you actually have on the device... but I remember seeing this before, possibly from Leviton, in the past.
In other news, a universal z-wave switch/dimmer driver set that pulls in all the settings from the device itself is almost ready for testing.
