This document provides some basic guidance on how to customize the Unifi Controller v5.6+ Hot Spot Portal feature. Existing documentation seems to be scarce in this technician's opinion.
This readme is the culmination of some exploration in customizing the portal for business use. Please note, all examples use the installed location of the Unifi v5 Controller software on the Unifi CloudKey.
Some issues have been encountered after upgrading the Unifi Controller to newer releases specifically with the Hot Spot Portal customizations on Unifi Controller versions greater than 5.10 relating to the use of these instructions. You may not have a choice but to upgrade your included default template to the latest version and re-modify your portal files.
