<![CDATA[Auto on/off of the TV (not the Pi)?]]>Hey Everyone,

I was wondering if anyone had any ideas on a good way to have the monitor/tv turn on and off automatically at specific times. I know there is an auto on/off module for the raspberry pi, but I was thinking this for the screen itself.

My mirror is set up with a non-smart tv that doesn’t have any options for auto on and off. I have a logitech harmony remote that I haven’t had a chance to try yet , but some quick googling makes me think it doesn’t have the auto start functions. Anyone have any (preferably cheap) ideas?

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)…

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.

I use a simple command in my crontab:
0 23 * * * vcgencmd display_power 0
0 6 * * * vcgencmd display_power 1

This 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?
(no other scheduled tasks running)

@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?

What are you logging in as? 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.

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.

@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?

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

Example setup: The pi is always powered on. I walk into the room, the PIR senses me, and sends a power on signal to my TV via HDMI CEC command, and the mirror modules are displayed.

After a set duration, if no activity sensed by PIR sensor, a power off CEC command is sent to the TV by PI.

Has this been done before?

Any guidance would be much appreciated.

Work/Family life has prevented me recently.

Slow and steady wins the race :)

@paviro just did want you probably want :)

https://github.com/paviro/MMM-PIR-Sensor

With this you can either turn of the HDMI signal (maybe your monitor goes to sleep then), or you can cut off the power signal of your monitor with a simple relay.
