This is a long-awaited feature and we have added this by popular request.
You can now see who has valid account to a hotspot, and you can also see, who is currently logged-in.
Go to 'Hotspot Locations'. You can see a router icon on the right, with two numbers next to it. It shows how many users have valid account (first number) and how many are logged in (second number). When you click on these numbers you can get a list of the users in details, with expiration, last login date and usage.
