Hey Juraj,

I think that you are over-complicating things.
This is rather easy to implement, you simply need to create a pincode-auth
scenario and for limiting the time you can use Max-All-Session attribute.

Be sure to check daloRADIUS as a management platform for RADIUS and Hotspots
deployments (if you're working with SQL databases, MySQL specifically though other
are supported too).

daloRADIUS - http://sourceforge.net/projects/daloradius/

I'll be glad to be of help if you need assistance in implementing this kind of
solution in your network.
