It looks like a standard on/off relay. No additional command sets or associations. ( although the manual says it has a second Association group, it didn’t have one at the time that it was certified so I’m not sure if that was implemented or not. But normally you don’t use those in a smartthings set up anyway. )
There are a couple of parameters that you can set, one gives you the option to use a standard toggle switch with it, and one causes it to remember its last status after a power outage.
You set those as a one time configuration. If you want to change them from the defaults, you can use the Z wave tweaker DTH just to change the parameter settings, then switch back to the generic on/off DTH
