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

JoeFranz

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.

Greetings Joerg

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

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…

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

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!!!

@grena
Oh, now another problem:
After switching off HDMI by MMM-PIR-Sensor-Lite the livestream-picture from MMM-RTSPStream is not in the frame when HDMI is switched on again by PIR .

grena

@Volkae, have you updated the module from the testing branch since your last message that it worked?

Volkae

@grena
yes, I did but I did not run RTSPStream while running the testing branch, sorry.

grena

@Volkae said in MMM-PIR-Sensor-Lite does not switch HDMI off:

yes, I did but I did not run RTSPStream while running the testing branch, sorry.

~~No problem, I’ll try to reproduce this issue!~~

MMM-RTSPStream is no longer being actively developed :neutral_face:
So, I refer you to the advice of the author of MMM-RTSPStream to find another solution:

:warning: This module is no longer being actively developed. I will accept PRs and leave the repo active, but will not be directly supporting any issues. If anyone is interested in assuming ownership of the module, please contact @shbatm. :warning:

Why?

I am no longer using this module on my own mirror. After several years, I found that I use the snapshots much more frequently than I streamed the actual cameras, which can be performed by much simpler modules and methods. To enable streaming, WebRTC (like MMM-HomeAssistant-WebRTC) is a newer and better standard with much lower server overhead and latency for delivering RTSP Streams to the frontend than any of the options used here, in the future, this will be the method I focus on and I will not try to shoehorn another technology into this module.

:fire: MMM-PIR-Sensor-Lite 1.2 has just been released! It’s allows you to manage monitor on Debian 11 Bullseye :sign_of_the_horns_medium-light_skin_tone:

Hello Grena… Hoping you or someone maybe able to help. I had to rebuild my MM (using Pi4b). With regards to using a PIR sensor, I’m using a doppler sensor vs. a PIR sensor using the following build thread:

https://forum.magicmirror.builders/topic/11704/update-replaced-my-pir-sensor-with-a-doppler-microwave-sensor?page=1

Everything prior to rebuild worked great… The screen would go into stand-by after 2 mins and flip back on when the sensor picked up presence. The repo I had, originally, used:

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

is no longer supported so I didn’t clone it. Instead, I used yours but having issues getting it to work. I can see the countdown on the screen but nothing happens. I unplugged the doppler sensor but no change. Any ideas? I’m running

Debian v11
MM v2.21

on pi4b. Any help is greatly appreciated

@dkhorse74 another user noticed this only worked for the 1st HDMI port on the pi4.

had to change the code in the node_helper.js for the second port

dkhorse74

@sdetweil
Thank you I will try… I ran:

xrandr -q

which show HDMI-2 is what is currently plugged in… Will report back

dkhorse74

@sdetweil
that did it! Screen goes to sleep… now need to figure out how to get the doppler sensor to “wake-up” the monitor

sdetweil

@dkhorse74 the module turns it back on… another place for the hdmi port…

the sensor just signals movement, usually a high signal…

the module then signals wake up and starts a time…

no more high signals, then sleep…

dkhorse74

@sdetweil
yep, understood… Still not able to wake up the screen… I tested the sensor with a meter and getting correct input voltage… is there anything I could be missing?

dkhorse74

@sdetweil
Found another post where you shared a link on how to run a PY script to test the sensor:

https://projects.raspberrypi.org/en/projects/parent-detector/3

Going to try this later tonight.
