Hi @vbec27 , you could create two networks -
SSID1 working only on 5Ghz
SSID2 for IoT, working on both bands (or 2.4Ghz only) - they can be bridged to same VLAN.
What you are describing is functionality called zoning (maping network profiles to groups of APs) on 'regular' Aruba Instant and it is not available on AIO.
