I don't have the device.. I better look it up 
and get some facts straight in my mind.
Fundamentally the question is (now) is this a 4-in-1 (two buttons, plus two relays)
From your initial "it's working" that I read, I was thinking it's just two relays with buttons internally connected to the relays.
The wiring diagram makes it seem like this is a dual relay only. The Fibaro 222 is identical to the Enerwave and Qubino dual relays. Those products support physical switches that drive the relays along with ZWave. All my advice was based on that assumption, and using that assumption, the glass physical switches on the Neo Coolcam device should function the same EXCEPT they also drive the include/exclude ZWave function.
You may wish to give the Enerwave driver a try:
