However,
could you explainwhat  part of the software creates
"/var/cache/vdr/acpiwakeup.time". Is it automatic as soon as you have
scheduled recordings?
   

It is written by the script S90.acpiwakeup that is called from the vdr on
shutdown.
 

As I read the scrip given in the link there is no way to use the scheduled recording time to automatically deduce the next wakeup time.

vdr provides the time in UTC unix time to the script as first parameter.

Or should a take a break or coffee?

yes
