{HowTo} turn on/off your monitor (Time based, PIR/Button, App)

Hey dude,
sorry for not answering, but i am only rarely here :(
First i would try to edit the config file:
sudo nano /boot/config.txt
try to uncomment “hdmi_force_hotplug=1” and try to uncomment “config_hdmi_boost=4”
maybe play around with some other settings.
https://www.raspberrypi.org/documentation/configuration/config-txt/video.mdRebooting the pi once a day is not the best solution :/
But however, if necessary:

@cruunnerr Thanks for the reply, apreciate it. I now have a 5050 LED strip wired up with the mosfets.
working with the pir script (removed the module as you advised others)what method did you use to run pigpiod deamon on startup. i added this in my crontab, guess that will do unless theres a better way.
@reboot /usr/local/bin/pigpiod -
If u followed the guide i posted, your PIGPIOD installation path should be “/usr/local/bin/pigpiod”
For autostart when booting u must edit the rc.local. Mine is like this:
pi@MagicMirror:~ $ cat /etc/rc.local #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. # Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi iwconfig wlan0 power off & sleep 5 & /usr/local/bin/pigpiod sleep 10 & /usr/bin/python /home/pi/pir.py & exit 0
So enter this via ssh:
sudo nano /etc/rc.local
and just put this into the file:
/usr/local/bin/pigpiod

@richland007 This wont be helpful but I will say I had a similar problem a few months back but now it works. Must be some configuration that changed in the mean time on my pi but I dont know what.

Hello there,
I’m currently planning my project and will integrate PIR sensor + related 2.1 method through HDMI.There is one thing confusing me :
- we talk about HDMI CEC in method 2.1
- nevertheless, it seems the PIR Sensor module is “only” turning HDMI output off and that is triggering "issues such as “powersaving / no input”.
But is HDMI CEC not allowing us to send a “turn screen off” command to the monitor instead of disabling the rasp. HDMIoutput and relying / hoping on the monitor’s behaviour?
Sorry once more if I mssed the point, but would like to understand before moving forward.
Regards

@bolish said in {HowTo} turn on/off your monitor (Time based, PIR/Button, App):

as I understand it, not many monitors/tv’s provide support for external power off/on commands…
none of my TV’s used for MM support this…
-
@sdetweil Maybe you’re right! I didn’t considered that.
But seems possible, correct? By changing the actual commands to the ones defined by the libcec librairy?
-
@bolish I do not know… as I said, none of my TVs support ANY commands to turn off/on…
in my MMM-SleepWake module, I use module.hide() to hide everything, leaving a blank screen… for those devices that do not provide external control…

OK, I will then try myself when I will receive my stuff and let forums knows if working or not.
