PIR sensor to turn monitor off. Nothing works :(

@elleclouds Hi, do you see any output of the Gpio module in the log file?

So I got it working with your tutorial. My only issue now is when the monitor doesn’t have a signal it turns completely off and won’t turn back on unless its unplugged and plugged back in. Is there a way to keep the monitor on, just asleep so that the HDMI signal when signaled, activates the screen?

[wishmaster270]

Hi,
it depends on your monitor. Maybe there is an option in the monitor configuration menu.
If not you can configure the MMM-Screen-Powersave-Notification module to only hide all modules and show the black background instead of turning the hdmi off (hideInsteadShutoff option)

[elleclouds]

@wishmaster270 Since the monitor would stay on… would that have any benefits? I can’t access the menu of the monitor due to taking it apart and not knowing where the button to access the menu is located. Thanks for all the assistance and advice, I appreciate it.

@elleclouds Black causes the display to turn off the backlight which saves energy. But it is surely less effective than switching the display to standby mode.

@wishmaster270 I’m using this in the config file but its coming back with an error. What am I doing wrong?

{
        module: 'MMM-Screen-Powersave-Notification',
        config: {
            delay: 60,
            hideInsteadShutoff:true,
            }
        }
    }

What am I doing wrong?

please use the markup for code or config info

mark the text, and hit the button above the editor </>

[elleclouds]

@sdetweil Did you change it for me, because it looks in the correct format? Any help with the code?

[sdetweil]

@elleclouds yes I changed it… know nothing about the module sorry

[sdetweil]

@sdetweil well, u have 1 more close brace } then u have opens {

{
        module: 'MMM-Screen-Powersave-Notification',
        config: {
            delay: 60,
            hideInsteadShutoff:true,
            }
        }                  //  ---- what is that guy?
    }

before u fix it run the config checker

cd ~/magicMirror
npm run config:check 

so u can learn how to fix them

For those unsuccessfully trying to put the monitor to sleep and wake up with PIR, are you running MM on pi4 with Rapsberian?
I never managed to get this combination to work. Instead I did succeed with Lubuntu on pi4.

Currently I have working PIR on pi3 with Rapsberian. No issue with this one.
Just the pi4 is so different and worse to configure sleep/wakeup.

Honestly, I would resort to an out-of-MagicMirror experience. I whipped up some python code using GPIOZero to replace MMM-Buttons, for instance…

@wishmaster270 Can you help me out with this?

[rafhtl]

I dont know if this is helpful but I use

/usr/bin/vcgencmd display_power 0
monitor off

/usr/bin/vcgencmd display_power 1

monitor on

works flawlessly
(ssh in pi and type the commands to try them)

r

[elleclouds]

@rafhtl Can you give me more context on where to input this and where it should go?

[rafhtl]

ok
if u are using MMM-PIR-Sensor
it should already be in the module
please try from ssh (you have to log in to the pi) and then type
/usr/bin/vcgencmd display_power 0
you should first try this to see if monitor responds to command
so first log in from a pc to your pi using putty
r

[elleclouds]

@rafhtl I was able to achieve this but my monitor stays off after a while and doesn’t come back on. Earlier in the thread I was suggested to just put the monitor to sleep but the code I used came back with errors. I needed help with those lines.

[rafhtl]

@elleclouds ok
You need to acces the monitor’s menu
I think I read you dont have a remote?
You need to access the energy saving menu
It musdt be something simple as that

[elleclouds]

@rafhtl can’t access it. Stripped down the monitor in my build a while ago

[BKeyport]

wait, the code comes back with errors?

do us a favor.

DISABLE the pir-sensor module for this test.

SSH into the mirror when you’re gonna be away for a couple hours.

type: vcgencmd display_power 0 - Monitor should shut off.

Go do whatever for a while. Come back,

SSH back into the mirror, and type vcgencmd display_power 1 Monitor should power on.

If the monitor doesn’t power back up, there’s a good chance the monitor isn’t good for your use. If it does, then we need to look at how it’s interfacing with the PIR Sensor module.

@BKeyport commands that work on pi3, do not work on pi4… many struggling with things that worked, but don’t now
