Turn off screen after certain time

[danielkastberg]

I would like to turn off the screen after midnight. Is it possible since flutter pi runs without X11 or Wayland?
I read online but all posts are mentioning something related to X11 or Wayland like "xset", "tvservice" or "xrandr" but no use since they require X11 or Wayland running.

Can this be done or do I have to turn the power off the PI during nighttime?

You can take my example of turning the screen on and off on the Pi4 https://github.com/DisDis/dslideshow/tree/master/deb_factory/template_build_arm64/opt/dslideshow/scripts

Thank you! I'm away from my PI but will test it when I get back. I used tvservice before and got "Can't find display" but then I know it should work for the flutter pi
