PIR Sensor won't wake up

jste84

I’m having a similar issue using Mmm-PIR-Sensor

Using a pi 3b+ and it turns the screen off but not back on again…

Having tested the commands it looks like
sudo tvservice -p doesn’t work with my monitor. (-o works though which is strange?)

Vcgencmd works perfectly though…

Could this be a reason why it’s not working?

@jste84 yes change the command the module uses

@sdetweil is it this line

sudo chmod u+s /opt/VC/bin/tvservice && sudo chmod u+s bin/chvt

That I need to change? Would I just change TV service to vcgencmd

@jste84 maybe. dont know. you could try

@jste84
i guess i have the same issue.
you can try easily with this module

https://github.com/bugsounet/MMM-NewPIR

you can change inside the module the mode

mode: 1 - use vgencmd
mode: 3 - use tvservice

in my case it works. But i think i have an adjustment problem.

The screen turns off and also the sensor can wake up the screen again.
But if there is no movement, the screen turn on randomly. Currently i have no solution. I guess there is some wrong settings on sensors Potentiometer.

@sceetch I came to a conclusion to not use any modules which do not show any info on the screen. So, in this case, I use a python script at boot which monitors a PIR and executes an HDMI on/off cmd ;)
