MM to run only between certain times
-
I am building a MM for my child based on a Pico projector and RPI. I would like the screen to come on at a certain time and then switch off at X time. For example start at 06:30 and close at 08:30 to avoid burning the projector.
Basically I’m building this into an R2 D2 shell, which will wake up with a Leia video (dubbed), then display weather/time for an hour or so and then shut off the projector/screen.
In theory I’d like this sequence in crontab:
06:30 switch on projector via USB relay
06:32 play leia.mp4 via omxplayer
06:34 load Magic Mirror
08:30 unload Magic Mirror
08:31 switch off projector via USB relayHow can I control Magic Mirror from crontab??
Should I play the video alarm before MM or within MM??
Any suggestion would be most welcome.
Thanks,
Andrew.

Thank you Jim, I will try those. Ideally I would like to go from Desktop to MM via crontab and back, without having to brute force it via pkill or similar.
Do you have any suggestions?
I need to be able run the relay scripts, or if connected to a monitor the vcgencmd command before and after MM.
Thanks,
Andrew.
