MMM-PIR-Sensor-Lite not switching off
-
Hi guys,
I installed my PIR incl. the aforementioned module.
I have configured the module to xrandr on HDMI-1 and verified whether it works on the command line, which it does.
Test of the sensor works fine too, module also sees movement and restarts the countdown.
However, when it reaches 0, the screen doesn’t turn off. I don’t see any log that it would want to turn off, neither when doing npm run start:dev nor through the pm2 logs.Just updated to v2.22.0, just in case - but no luck.
Any ideas or pointers?Thanks

Found the error - xrandr needs a sudo in front, otherwise it doesn’t execute.

@djlagaffe It’s the one module I’ve never been able to make work… I’ve tried everyone I can find, I’ve check to make sure I have the correct pin number and that the PIR itself worked but I still can’t find one that does the job… I’ve not even had any luck with the EXT-PIR on 4th party modules and not been able to make that one work. I wish you all the best and I’ll be watching and hope you find the problem. I’ve been watching for some answers but not yet…
Good Luck

@N6NG did you run any of the python test scripts to verify that the sensor works outside of MagicMirror?
if it doesn’t, then MagicMirror can’t fix it…

@sdetweil No. are they yours?.. I’ll take a look…

@djlagaffe also note the info in the doc after the options table about problems with bullseye and/or buster

@sdetweil : I did check with the scripts and the PIR itself works. I have also activated the countdown timer, thus the communication between the PIR, the script and MM in general works. What I do not see is that the command to switch off the screen is executed (or even sent).
I have verified the script and the command to check whether the command itself works on my installation, and yes, it does.
So it should be something not triggering the switch-off / on command. However I have not been able to put my finger on it yet… -
@sdetweil : yes, however no luck or any log entry at all in pm2 logs mm - am I looking in the wrong place?
-
@sdetweil Sorry, one add-on no debug messages either in the logs, nor via npm run start:dev
