@BlazeStar hey there,
as @johnpoz already mentioned:
set up VLANs on switch and pfsense, make sure it is working
create new networks with PVID (as set in 1.) on your cloudkey controller software (under networks)
create (under wireless networks) your new wlan networks with ssid mapped to network > VLAN1, 2, 3 etc
Done.
:)
