NEXA AN-179 Input switches

Hi,
This device has 2 switch inputs and 1 output. When I add it to Vera the switches won’t show up as devices. I try to understand the manual to see if there are any statuses I can check to detect the state of the switches, but I can’t find that. I am by no means a z-wave expert.
So my question is
Are the switches’ states detectable in some way?

I want to use the inputs to start the device for two different time periods, i.e. one button should leave it on for 1 hour the other for 4 hours
