We changed the naming of posbox to IoT Box everywhere and renewed the web interface using jinja2 templates in separate html files. A separate configuration for the server and the IoT Box name was added and it shows drivers for both pos and iot. The interface also needs a step to step wizard that is launched when the access point is active for simplified configuration. Thanks to qle and Deep Patel.
