Expected end of the current Toies via MQTT

[FragForward]

Is your feature request related to a problem? Please describe.
I would be delighted if I could see via MQTT (Homeassistant) how long the current Tonie will (presumably) continue to run. Since I need to check on my children after Tonie ends, if they are not yet asleep, I would like to be notified 5 minutes beforehand.

This is nearly impossible to implement, as we do not get the data from the Toniebox.
This would be hard guessing.

OK, I understand, but would it be possible to output how long the current Toni would run in minutes? This data should be available on the server, right?

This would be a great enhancement if I could display the expected end time (without doing a fast-forward or pause)
