Thanks!

some points:

• we should make canteen menu optional, so e.g. if there is no module in school edupage instance, than there is no entity for it. Do you think it's possible?
• when I test this branch I dont have any grade sensors anymore and student_name is None in notifications sensor (it crashes unidecode) and also calendar is no more functional. Even if remove integration and reinstall.
• I dont have lots of spare time atm due to real life work but I see you are getting deeper into the rabbit hole day by day :) thanks man

• Im afraid we don`t have the information from edupage-api if lunches module is on/off
• do you see any error in your log? (coming from custom_components/homeassistantedupage/homeassistant_edupage.py, line 134)

• "failed to fetch timetable:" word "timetable" is to be removed cause the try/except block handled all data. Maybe we should try/except all steps alone, but in this case its because of the missing data of get_lunched():

2024-12-17 13:42:30.120 ERROR (MainThread) [custom_components.homeassistant_edupage] INIT Failed to fetch timetable: EDUPAGE error updating get_lunches() data for 2024-12-17: list index out of range

• next error is because unidecode tries to access a None object:

2024-12-17 14:22:45.286 ERROR (MainThread) [homeassistant.components.sensor] Error while setting up homeassistantedupage platform for sensor

• We can return None if there is an exception in get_lunches(self, date): method. But Im not sure if this is proper way to go as Im new in python and also cannot really reproduce. What do you think?

• Regarding unidecode error - I dont see a point why this happened as unidecode was not added or changed in this PR.

• the get_lunch problem should be handled in init.py by catching the error with try/except and only create lunch sensor if there is data
• the unicode error happens because the student_name is of Type None, this must be catched

Regarding "unidecode" issue - I guess its related to this bug #70 and should be solved separately. Would someone be able to overtake that pls?

I'd go for it but have 2 full range offsite working days and will not be back before friday.
