Good evening

I’d like to see my MagicMirror restart at a certain time each day. What should I enter in the crontrab? I have already tried x variants, but unfortunately it never worked.

27 17 * * * Command pm2 restart mm

The sudo reboot command works fine.

27 17 * * 5 sudo poweroff

Did you forget to write the full command? Try pm2 restart mm.sh
By the way: I prefere the online crontab generator (https://crontab-generator.org/). It’s very easy.

Thanks for the link, but it still does not work

Sounds strange. Maybe you first have to stop the pm2 process before restart, with pm2 stop mm.sh. Don’t forget to complete the line für den reboot am Samstag - sudo reboot >/dev/null 2>&1

Why do you want to restart MM? Maybe pm2 reload mmis the better option.

Why … that’s actually a good question. The problem is that if I bring the screens for about 5-6 hours and then turn back on that no picture appears on the monitors. Therefore, I would like a regular restart of my MagicMirros.

Are you using the GoogleMapsTraffic module? In that case the pm2 reload mm will do. Or a simple Ctrl+R on the mirror. The cronjob should then look something like 55 19 * * * pm2 reload mm (mine is 0 6 * * * pm2 reload mm and it works flawlessly).

Exactly, I use the modules GoogleMapsTraffi on these two monitors and these two monitors will not wake up after a while, if I turned off the monitors for several hours.

Then tonight I will try pm2 reload mm. Unfortunately, the command pm2 restart mm did not work. Then I’m curious.

Depennding on the other modules you’re using it might be good to reload MM more than once a day. In my case once is enough. Without reloading the screen turns black after more than one day. Depending on your setup it could be better to reload it twice or 4 times a day. In the end the reload is very quick and you won’t notice anything.

Perfect, did not know that I can reload the MagicMirror. Have always made a restart in the past. I’ll give feedback this evening on whether the cronjob works with the pm2 reload mm command
