**Is your feature request related to a problem? Please describe.**
HTWK changes with Projektmotor the Event information infrastructure and we have to adopt our fetcher to gether all data from https://stage.luna.htwk-leipzig.de/api/docs

**Describe the solution you'd like**
Rewrite fetcher in v3 for additional Event Fetching.
Projektmotor said that its the "single source of truth"

**Describe alternatives you've considered**
Alternative is to contact HTWK internals to get own access or rewrite internal infrastructure, because this api isnt a reactive one. Information Updates are done by fetching and getting informations from an manual file. Best case every 10min or every hour.
