Nothing there right now.
I want to share what I found. I installed official app for Android, established a connection between it and IT4WIFI. Here is the logs of communication (rename it from xml to txt):
162E9DF9383_TLSv1.2_443_34930__.xml (14.6 KB)
162EDDD4A03_TLSv1.2_443_57914__.xml (21.2 KB)
The source code of the application can be obtained by decompiling the APK file, I do not know whether it can be distributed.
