I'm trying to add/include some of the Inovelli LZW42 RGBW bulbs to my Zee S2 running HS4. When I run the Add/Include a Node action from the Z-Wave Controller Management page, it sees the bulb immediately, but then:

Add Node started...
Activate the 'Add to Network' function on the device...
A new node is being added...

Done. Node 42 Added.

All associations for node 42 have been retrieved successfully, it supports associations on these groups: 1.
Root Node Device Node 42 Z-Wave Switch was created for node 42 on network EC46A97A
Internal: Adding association for Z-Wave device Node 42 Z-Wave Switch (Node 42, Group 1) to HomeSeer
7 out of 7 Child devices of node 42 were created successfully.
The bulb then shows up as a Device, with controls for Cool / Warm White, R, G, B, Custom RGB, and Switch Multilevel Channels. Of these, only the Cool and Warm White channels respond to the controls at all. I'm assuming this is at least partially because of the "SECURITY SCHEME" warnings.

Things I've tried based on Google searches:
  • removing/excluding the bulb before each attempt
  • factory resetting the bulb
  • moving the bulb and the HomeSeer within 6" of each other
  • adding the bulb insecurely -- succeeds, but same problem, almost no controls work
  • different bulbs
  • opening a ticket with Inovelli (this evening, no reply yet)
This is early in my learning curve for HomeSeer and Z-Wave, so it's entirely possible I'm doing something dumb, but I'm stumped. The Inovelli site explicitly mentions that these bulbs work with HomeSeer and they have specific instructions for this process (which is what I've been following), so I keep having to think that this -can- work.

Any thoughts? Thanks in advance.
