MMM-PIR-Sensor-Lite does not switch HDMI off

[Volkae]

My MM works fine but I have a problem using MMM-PIR-Sensor-Lite. The modul is running, the countdown is shown on the MM but when the countdown shows 0 it does not switch HDMI off so the monitor is still alive.

What can I do??

[sdetweil]

@Volkae this module requires python3, which is not installed by default… and not listed in the requirements

[Volkae]

@sdetweil
Python3 was already installed (up to date).
Module seems to work fine but does not switch HDMI off…

[sdetweil]

@Volkae so have u tried the command it uses, on the terminal window

from the code

/usr/bin/vcgencmd display_power 0

make sure to do this over ssh, so you can turn it back on

/usr/bin/vcgencmd display_power 1

[Volkae]

@sdetweil
then it shows me:

display_power=1

HDMI is still alive…

[sdetweil]

@Volkae those two were off and on

if you do off

does it turn off?

[Volkae]

@sdetweil
No, it does not switch HDMI off

[sdetweil]

@Volkae works perfectly on my pi 4…

what pi version are you using?

[Volkae]

@sdetweil
I´m using a pi3.
Maybe that´s the problem??

[sdetweil]

@Volkae worked on my pi3 as well…

[sdetweil]

@JoeFranz @Volkae this appears to be a problem related to the raspi os kernel level

Thanks @sdetweil for the link :-)
It is probably due to the current firmware 5.15
With

rpi-update b976c54917e240630c05a9b383010f1492bc61b4

I installed version 5.10. It now works again with the standby on the HDMI connection.

all these modules and all these guides you can find online all fail to tell you that at some point a kernel or driver update broke vcgencmd and tvservice commands for the newer pis or Rasberry OS. I spent so many hours making mine work.

xrandr --output HDMI-1 --off

xrandr --output HDMI-1 --auto

these worked for me, maybe they’ll work for you, I dunno.

[sdetweil]

@blouzbee cool…

yeh tvservice went away in bullseye

they are trying to get rid of all the old ‘raspberry pi’ unique stuff to maintain

[Volkae]

@sdetweil
Seems that there is no way for me to swich off HDMI via PIR-Sensor :-(

Maybe I will find a way to do this with a python-Scrip out of MagicMirror but I´m a just a beginner and it seems to be not easy…

[sdetweil]

@Volkae did u see @JoeFranz post about changing the OS firmware down a couple levels?

@sdetweil
I will try to downgrade

Hello all,

I think I have restored the compatibility of MMM-PIR-Sensor-Lite with Bullseye (lastest firmware). See issue on GitHub and more information in ReadMe

Can you install the testing version to confirm the resolution of this issue?

cd ~/MagicMirror/modules/MMM-PIR-Sensor-Lite
git pull
git checkout testing

Thanks for your feedback!

@grena
Hey grena,
seems to work fine on my Raspi 3!!!
Thank you, great support!!!
