Openhab 3 binding Automower DateTime

Hi

System Openhab 3 on Windows 10

I would read the items from the Automower binding.
It workswith Battery state, Activity state but I can’t read the DateTime state from NextAutoStart.

I have changed the item State Discription with “%1$tA %1$tH:%1$tM Uhr”, so I the there
the weekday and time.

Thanks for reading.
