I’ve developed an integration to provide a sensor for the current “Vertretungsplan”, i.e. class substitution schedule, of the Heinrich-Hertz-Schule, Hamburg. The integration pulls the official school data from the password protected website and lists the relevant events for your kid as an attribute list in the sensor.
This is obviously only useful when your kid is visiting this special school. But maybe it can serve as an example for other parents as this data is tremendously helpful in a hectic morning and Home Assistant can automate on it by sending notifications, e.g. that the first class is cancelled.
You can install this as a custom repository in HACS:
In Lovelace, I visualize the data like this:
