Hey everyone,   I would like to create a guest wifi which can be accessed by using a free voucher. The voucher has to be limited to a specific amount of time (e.g. two days). The user should connect the device to a non-encrypted wifi displaying a splash screen. There should be no possibility to buy an access code - only the predefined ones should work.   I have set up Meraki with these settings:   Access control / Network access / Association requirements: open (no encryption) Splash page: Billing (paid access)   Access control / Billing plans / Free access: disabled Prepaid access: use fast prepaid login page   Splash page / Splash behavior / Splash frequency: Every day     I can create prepaid cards but they have to be setup with a balance. How do I create a guest wifi like mentioned above without using any balance (I did not set up any pricing/billing plans).   Regards Chris ...
