Much, much delayed: after messing with this thing for months I *finally* figured out how to get my Enerwave ZWN-SC7 included and working with openhab.
I performed all of the following operations manually using my usb stick and zensys-tools (google for the Windows download).
1) Enable Network Wide Include (that's the big asterisk) on the controller.
2) Associate the SC7 by holding the big button, then pressing top left, middle left, bottom left in order. The tool won't exist NWI, but in the log it should say "node added to network".
3) *manually* configure the association groups for the controller. zensys-tools appears to have a bug where a single node can't appear in more than one association group, and/or multiple groups aren't properly defined. The only way to do this is manually sending the following z-wave commands from the "command class" tab:
a) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 1, Node ID = [your controller ID]
b) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 2, Node ID = [your controller ID]
c) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 3, Node ID = [your controller ID]
d) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 4, Node ID = [your controller ID]
e) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 5, Node ID = [your controller ID]
f) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 6, Node ID = [your controller ID]
g) COMMAND_CLASS_ASSOCIATION_V2/ASSOCIATION_SET, Group ID = 7, Node ID = [your controller ID]
4) Now, manually set the scene controller configuration so it sends the scene activation commands to your controller. Again, from the "command class" tab:
a) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 1, Scene ID = 1, Dimming duration = 0
b) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 2, Scene ID = 2, Dimming duration = 0
c) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 3, Scene ID = 3, Dimming duration = 0
d) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 4, Scene ID = 4, Dimming duration = 0
e) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 5, Scene ID = 5, Dimming duration = 0
f) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 6, Scene ID = 6, Dimming duration = 0
g) COMMAND_CLASS_SCENE_CONTROLLER_CONF_V1/SCENE_CONTROLLER_CONF_SET, Group ID = 7, Scene ID = 7, Dimming duration = 0
Now, when you tap buttons on the SC7, the last one you tap should stay lit. You should also see the SCENE_ACTIVATION_SET messages in zensys-tools. At this point you should be able to go back to openhab and bind to the scene messages.
good luck!
