You can use this tool to build coffee or restaurants free wifi hotspots, without pay external cloud services. Works with Ubiquiti Unifi controller version 4.X and 5.X
NOTE: I'm working for new Springboot/Angular implementation, with microservices and monolithic versions (this will contain Espresso Admin and Espresso Portal in a single package)
It requires:
- Ubiquiti unifi access points
- Server host and web server with php support (Apache2 or Nginx) and Unifi Controller
- A RDBMS (Mysql o Sqlite3) with PDO support.
