@Assassins
I would like to see this script. Please.

This is all I use in my crontab -e
15 07 * * * pm2 start mm
30 21 * * * pm2 stop all
Shuts MM down at 9:30 pm
Starts MM backup at 7:15 am
EVERYDAY.
I have a Black background color and the bar at the bottom using black background which makes it look like the screen is off basically.
That way it doesn’t flood the room with light at night.
Also less read / writes to the ssd drive I use for my MM.

My old crontab does not work in debian 12 aka bookworm
Is there something i need to add to it to get it to work again?
Really liked how it worked and the fact that I was getting a fresh restart of mm every morning…

15 07 * * * pm2 start mm
30 21 * * * pm2 stop all

Tried this too.

15 07 * * * pi  pm2 start mm
30 21 * * * pi  pm2 stop all

@plainbroke what userid did the pm2 jobs get created under?

plainbroke

@sdetweil
pi is my user. I know not very original or safe but it is on a closed network.
that is why I tried the pi user in the crontab.
and it shows up when I do crontab -l.
So I think it is setup under pi correctly.
Do I need to do it as root sudo crontab -e and use pi or root as the user?
