Scheduling a blackscreen?

[garbleflux]

Your monitor should handle the cec-signal (Consumer Electronics Control).
I use very successfull the following crontrab

Stopp und reboot at 8 am

59 7 * * 1-5 sudo pm2 stop all >/dev/null 2>&1
0 8 * * 1-5 sudo reboot now >/dev/null 2>&1

29 9 * * 0,6 sudo pm2 stop all >/dev/null 2>&1
30 9 * * 0,6 sudo reboot now >/dev/null 2>&1

Anschalten des Monitors Wochentags um 8 Uhr

turn on monitor weekdays at 8 am

0 8 * * 1-5 echo “on 0” | cec-client -s -d 1 >/dev/null 2>&1

Anschalten des Monitors am Wochenende um 9.30 Uhr

#turn on monitor on weekend at 9.30 am
30 9 * * 0,6 echo “on 0” | cec-client -s -d 1 >/dev/null 2>&1

Ausschalten des Monitors täglich um 20.30 Uhr

#turn off monitor daily at 8.30 pm
30 20 * * * echo ‘standby 0’ | cec-client -s -d 1 >/dev/null 2>&1

When u use a RPI… use a relay for power if nothing helps. So you can set the time like described.

2nd possibility - use a Tasmota device and define rules.

@oberfragger STRONGLY recommended NEVER to power off pi as a solution instead of shutdown cleanly…

[OberfragGER]

@sdetweil I agree. But - I said not turn off the RPI. I said- rurn of the monitor with the help of a relay!

@oberfragger ah… got it…
