Now the only issue you may have later down the road is that those Fibaro Dimmer 2 modules do not support S2. Because of that it's very likely they will have included with S0 security which is very bad. Apparently S0 is very chatty and will slow down your network. I'd strongly recommend getting hold of a USB Z Wave stick and the SiLabs Simplicity Suite software (and load Z Wave Controller module). That will enable you to to include them with security set to 'none'
Unfortunately once they're included you can't change the security - you have to start again - excluding and then including the device without security. With a C7 or C8 that is only possible using the aforementioned method. It's nothing to do with Hubitat, it's down to how the SiLabs SDK works on the 700 and 800 series chips (enforcing inclusion with S0 where S2 is not available). I have about 16 of the Dimmer 2's and had issues early on.
