I use about 30 z-wave devices in my setup. Mostly FGS-222, FGS-223 and FGR-223
You will find comunity drivers do a good job.
I do advise you follow the post instruction best practice to building your Z-wave mesh and include the devices accordingly.
My only real issue with Z-wave right now is that occasionaly upon a scene sending commands to a large number of devices the process takes longer than expected to send data to all devices. This is a known issue and I hope it will be sorted out with the new release announced today (did not check yet).
Good luck in your new challange
