I’m getting started with HomeGenie and z-wave at the same time, after years with X-10 and Lightolier Compose. I’ve got an Aeon Z-stick gen5, and a few Vision dual relay modules.
That worked for me! I had to first restart the Multi-Instance program,
then the parameter appeared in the edit box, then after setting it to “2” I
had to restart the server before the two switch instances appeared as
modules.
