PIR problem

@Peter
No stupid question more a lack of information/documentation of me ;-)

You can call the script with the GPIO number as first argument. In your case it should be:

./testGPIO.py 17

After some research i am pretty sure the problem is the graphics stack in your case. I am working on a solution for the problem

@wishmaster270 great!
I will try it as soon as I find time …
Have a nice evening!

I was not able to use vcgencmd under bullseye and AFAIK they are using xrandr under the hood for rotating the screen over the web ui menu.

So beside testing if the sensor works you could test if you can deactivate the sceen with xrandr --output HDMI-1 --off and activate it again with xrandr --output HDMI-1 --rotate normal --auto.

xrandr is also the default of commandType option of MMM-PIR-Sensor-Lite (see documentation).

@karsten13 I tried MMM-Pir-Sensor-Lite: counting down works and is re-activated whenever I move my hand in front of the sensor.
But the screen does not turn off.

Just released version 0.0.7 of my MMM-Screen-Powersave-Notification module which supports either vcgencmd, tvservice and now also xrandr.

Peter

@Peter and if you issue the commands yourself(via ssh)

do they work?

Peter

@sdetweil did not try that.

@Peter Hello Peter… I’m not sure I understand… I ran the following test on my mirror and it worked as it should.

/usr/bin/vcgencmd display_power 0; echo “Display should now be off”; sleep 20; /usr/bin/vcgencmd display_power 1; echo “And now it should be on again”

But now I need to incorporate it into my config.js for my MMM-PIR-Sensor-Lite. I see the command type and ‘vcgencmd’ but once I get that in the config how do I do the turn on and turn off?

Thanks for all the help and you also Sam.
