Hi,
something is still not ok with the cronjob for shutdown.
The idea is to shutdown the system @01:00 Hrs and 15 mins later power is cut off by a shelly plug S
As you can see the system changes the time and continues to do something until the power is switched off. With that I could life but when the system is started next morning the internet connection is not working. Not internally or externally. Quick solution in the morning is “power off & power on” and bingo everything works as planned.
I forgot to mention that I have also a Raspi 4 which is setup more or less identical ( dietpi up to date , shutdown same time , power off with a shelly Plug ) and but
no problems
