Boot/Shutdown on timer

[captainmorgan]

The brut solution would be a timer directly on the power plug ! But it is no a nice solution.

I think I'll try this. Sounds like the simplest solution. But I'm also interested in your first idea, what kind of controller would I need?

There are many timer projects with arduino (comprizing arduino pico) on the web, but unfortunately I have no time to try. The advantage with a timer on the power supply is that you cut all sources of power consumption (even the 12V converter) only the timer would consume energy (hopefully less than rockpro64 at idle).

Thanks, yes I went with a digital timer for the socket and that's working great!
