PIR Sensor ??

I’m not yet that good with Python, so some parts are a bit hard to understand.
I’ve seen a couple of modules/posts over here and gave them a shot.

One was working half. Screen turns of but no way to get it back on.
This was: MMM-Pir-Sensor

Just found a dutch how-to: here so i will give this a shot.

off is easy, PIR doesn’t report , so nobody there, by default, so turn off…

make sure u have ssh enabled, so u can get in from your PC and turn display back on…

put the sensor is not reporting, or the module config isn’t looking at the right GPIO pin .

make it work outside MM… then it will be better

Alright i got i working with this guide.

The only thing i’m now facing is, and i can’t understand this, that i get the message “Cable not connected” on my display.

When i was using it in crontab with “vcgencmd display_power 0” (timebased) it put the monitor in sleep mode and the led’s of the monitor turned off.
Now when using it in a .sh command the monitor stays on with this message.

Do you have any idea?

[sdetweil]

@mdlefevere well, when u ran in cron, you ran as root

in your script do you do

sudo vcgencmd display_power 0

sudo vcgencmd display_power 0

No i don’t
But i tried it already and didn’t make a difference.

Also if i sudo su and then use vcgencmd display_power 0 it’s not sleeping.

@mdlefevere this is where I have trouble… all my displays behave as u describe…

turn off the hdml and then they holler about no input… , and 15 mins later power off (energy start complaince) …

@sdetweil

Hmm alright.
So do you have a “workaround”?. How do you handle this?. I just want the screen to be not on all day long when i’m just home for a couple of hours

[sdetweil]

@mdlefevere I use module hiding. never turn the display ‘off’

[MDLefevere]

@sdetweil

Ahh so. But doesn’t the backlight stay on all nigjt?. Not very energy efficiënt 😋

[sdetweil]

@mdlefevere yes. but can’t turn it off programatically… what else can I do?
