Newbie - Honeywell VAM & Vista 21iP & Zwave

I want to operate all devices from one system.

Devices I have:
Honeywell HRDP DVR camera system
Honeywell VAM
z wave devices
Honeywell Vista 21iP

My issue is that the Honeywell VAM doesn’t support all of my z-wave devices. It seems that it is more limited than I expected.

Can anyone direct me on how I can start?
I thought about using the Alarm Decoder AD2PI but I’m not sure of everything I would need.
Help is greatly appreciated!
