WebUntis - WhatsApp Bridge/ChatBot

This tool is a chatbot for WhatsApp to retrieve data from the timetable app/website WebUntis for schools and universities.

The repository is still under development and might contain some bugs. Please report these bugs so I can fix them as soon as possible :D

Features

Timetable Live-Updates

If there is a new substitute lesson or a class is cancelled, you will receive a message via WhatsApp.

ChatBot with Untis-Data

You can also chat with this bot via private message or in groups. Below you will find a list of all the commands this bot can use.

Unfortunately, the commands !teacher and !room only work with a WebUntis account that has access as a teacher.

All Commands:

Command	Alias	Description	needed WebUntis-Access
config	configure	configure Chat-Settings and create links to WebUntis	student
eval		execute evaultation commands (only Admin)	/
ping		just a normal Ping :D	/
room	raum	check the current class in a room	teacher
teacher	lehrer	search in which room a teacher is right now	teacher
