Auto on/off of the TV (not the Pi)?
-
CEC implementation is far and wide on monitors/tvs. There’s a client for the Raspberry Pi that you would have to install yourself, possibly (re)compile for your specific setup, and see if it is even able to communicate. This part is outside the scope of MagicMirror, like way out there. :)
You can start by reading the rpi forum: https://www.raspberrypi.org/forums/viewtopic.php?t=15749

Re: Auto on/off of the TV (not the Pi)?
@MechMatt This is nearly the exact setup I would like to implement but without the PIR sensor. I’ve already checked and my Vizio TV is CEC compatible and Ive got a Pi3 with Jessie 8.0. Ideally I’d like to display the MM just from 6-9 am and again from 7-10 pm. Did you make any progress with a script or service that would allow timed display power changes?@KirAsh4
I had already found the link you referenced and in trying to go through it the instructions falter. I’m following the setup listed towards the bottom of this site but when I get down to sudo git clone https://github.com/Pulse-Eight/libcec.git I’m prompted to login to get hub but then just get “remote: repository not found.” Any ideas or advice? -
Turn the monitor on and off automatically
To turn the monitor on/off on a daily schedule, grab this script and put it in /home/pi/rpi-hdmi.sh. Next, make it executable:
chmod +x /home/pi/rpi-hdmi.sh
Now we’ll need to add a cron entry to call this script at the desired time, so open the cron editor:
crontab -e
And add the following lines at the bottom of the file:
Turn HDMI Off (22:00/10:00pm)
0 22 * * * /home/pi/rpi-hdmi.sh off
Turn HDMI On (7:00/7:00am)
0 7 * * * /home/pi/rpi-hdmi.sh on
The first number (0) is the minutes and the second number on each of those lines (22 and 7) is the hour in 24 hour time. So in this example, the monitor would turn off at 10:00pm and back on again at 7:00am. Adjust the time for your needs.
Keep in mind: this does not turn the Raspberry Pi off! It just turns off the monitor, saving energy and hopefully extending the life of your monitor. The Raspberry Pi is still on and running however.

The
'sudo'command is local to you (your rpi), so that password is your regular user’s password (possibly the'pi'user, in which case you should not need it as it’s already configured to be allowed to run'sudo'.) I can run it just fine and it clones that repository as expected. -
I use a simple command in my crontab:
0 23 * * * vcgencmd display_power 0
0 6 * * * vcgencmd display_power 1This turns the monitor off at 11pm and back on at 6am.

I’ve configured the monitor off with display_power 0, but the next morning my raspberry pi is also shutdown… Any tips?

@mdissel
Just power your rpi on?
If you want to power on your rpi schedully, you should use poweroutlet with timer function or something like smartoutlet.
If your problem is unintentional RPI’s poweroff, this could be another issue. -
Yeah my project stopped just because of this same reason…
Prob is, that I’ve made MM on my rpi 3 and bought sonoff relays for turning on and off my tv, but the prob is, that when I power my tv it doesn’t start. It just gets its power and I need to use my remote for it. Now… if I would have some sort of remote app of some sort with wich I could control my tv, then this could be the answer (maybe some android remote or something)…
