Ok, so I’m still digging on this… I also found this reference on the HomeSeer board:
If you scroll down, there are some good pics showing the zwave info. One in this one also indicates something else happening. Though, in this one, it calls it a channel (Channel 2 specifically), not a device… Doing a little digging on the ST boards relating to multi-channel, instead of sub-device, I came across this:
It looks like the CT100 may be using an older style(?) of zwave communication for this. If so, there’s some code in there that might help. I’ll keep digging and see if I can find anything more solid.
