I don't think AeroHive has this capability. I have setup the system to email me a report every month to help me track this info.
Selected Reports:Unique Wi-Fi Clients over Time Top 10 Aerohive Devices by Wi-Fi Client Usage

I am using On Premise and run reports several times a week. I am currently tracking BYOD usage between 8 and 5 to show impact on our business operations for those guest devices. I'm able to pull up a report for that criteria for a 1 month time period w/o problem. Just does not have the drill down I'd like to see for who was connected at the time, but the bandwidth usage does exists.
