It is interesting it doesn't work on your device. The difference between the in-box and my driver is that it sends a basic OFF command, whereas I dump the switch to 0 level via the setLevel command.
My de vices are mainly:
applicationVersion:5.26
zWaveProtocolVersion:4.34
So mine are older than yours. It would be easy enough to switch the off to a basic set command, though. Maybe this weekend.
