Just a heads up to Garrett (and all),
I have updated to the latest 4.1.1 (although, I guess it isn't officially released yet!)
I have the Z-Wave module for my ISY. I have started updating the code for Z-Wave items. Currently, everything looks like a binary switch or lock (no dimming of lights). I have binary lights working, and dimmers (as binary on/off). No locks yet.
It is a little odd, since so far, all device are Category 4, with different subcats (relays=16, dimmers=17, locks=64). This sort of goes against the Insteon categories, but for now, I am going with it.
I will wait to post any updates until more is worked out tonight/tomorrow (regarding the beta/untested status).
