Help! Probem using PIR Sensor on raspberry pi zero to turn on/off screen
-
Hi all,
i followed every step of this post :point_down:
@randombullet said in How I got my Magic Mirror working on a Raspberry Pi 0 (zero):I’ve been working on this for a little bit and I’m sorry for all the incoming questions and posts on here.
On sudo npm install, I get npm ERR! code EPEERINVALID.
I’ve tried googling some answers but I’m not confident enough to figure this out. Also I’m writing the steps in a more linear way to make more sense of it this is what I have so far and I’d like some input so that I can help other people.
Step 2
My Jessie Lite didn’t allow me to create files for some reason. I posted on reddit here.Anyways the way of going around this is to put in a “wpa_supplicant.conf” file into your SD card and put the following in:
network={
ssid=”YOUR_WIFI”
psk=”WIFI_PASSWORD”
}This is what I have so far. Please look over this. Thanks in advanced!

I’ve a python script to test the pir sensor. Motions are detected but my mirror still turned off.does anybody have an idea ? :expressionless:

Pir sensor module works fine. Screen wakes up.
I stil have nothing on screen, no smart mirror. -
@Petal0u did u ever get to solve the problem? I’m currently in the same boat.
Cheers,
Mike -
Have you disabled screensaver? That can cause the screen to remain blank.
Easiest way is to install xscreensaver then disable it from the desktop (yes this seems counterintuitive but it works)

Hey! Thanks for getting back to me.
My MM works pretty well, can’t get MMM stock to work though.
My major problem is getting my PIR sensor to function properly. I have it working properly on a pi3 but not the zero.
What code did u use for your PIR?Thanks,

If I remember correctly, that module’s API is no longer working, thus, killing the module. :-(

@Mykle1 Good day!
That’s interesting, I have MMM stock working on my Pi3. I am running an older version of Jessie though.
For you know of any stock ticker that would work on Pi Zero?Thanks,
Mike -
Obviously, I am mistaken then, and I apologize for an old man’s faulty memory. :-/
I don’t know if this is what you are looking for or if it works
on a Pi zero -
@Mykle1 Many thanks, I’ll give it a try!
I have a few more avenues to explore I respect to the PIR sensor and will report back if successful.
Cheers,

maybe this is helpful
The very important thing is, that your monitor supports HDMI-CEC or ARC. Otherwise u will not be able to turn it on or off via HDMI. To reassure you, most monitors do this ;) To check if it works just go into terminal via ssh and type: sudo tvservice -o to turn off sudo tvservice -p to turn on edit: for some monitors the following commands work better. Please use them if your monitor needs it: vcgencmd display_power 0 to turn off vcgencmd display_power 1 to turn on
