MMM-PIR-Sensor - White Screen
-
I made an attempt at fixing it but I struggled to find many JavaScript/Node.js tutorials out there. I have however managed to compile a straight forward script in Python that I have set up to run with pm2. A workaround for those who are in high demand for the motion sensor to work and to give paviro some breathing space.
Sorry but I don’t know how to add this as code snippets. If a mod could help me out that that would be great.
Open Python 3. File > New. Paste this code in.
from gpiozero import MotionSensor import os pir = MotionSensor(4) #4 is the Pin? while True: if pir.wait_for_motion(timeout=10*60): #10 * 60 Seconds os.system("/opt/vc/bin/tvservice -p") else: os.system("/opt/vc/bin/tvservice -o")You can if you want edit
os.system("/opt/vc/bin/tvservice -p")
to
print("Motion Detected")
to test if your PIR Sensor is working ok. After changing it, save it and press Ctrl + F5 to run the code. It will then spam up with motion detect or undetected depending on what you’ve changed.Moderator’s note: You can use backticks (`) to highlight code.

Hi there,
I think I fixed the problems now, feel free to give it a try :)Cheers,

@James sure this is because of my plugin? I used the latest and it worked :/
-
@paviro maybe 99% sure. FYI what I did yesterday as follows:
- Format & rewrite the sd card,
- Boot and run
sudo apt-get update & upgrade & reboot, - Install MagicMirror2 with the bash command,
gitMMM-PIR-Sensor in modules folder and runnpm installin MMM-PIR-Sensor folder as well as useradd command,- Add code in
config.jswith
{ module: 'MMM-PIR-Sensor', config: { sensorPIN: 4 } },- After rebooting, run MM with pm2 and shows “White Screen”, I checked the pm2 error log shows something like “Expected 49, got 48” as before,
- Run
npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=49in the MMM-PIR-Sensor folder, - Run
pm2 restart mmand it works.
I found there is another issue when a rebooting finished and MM runs automaticly with pm2, MMM-PIR-Sensor will not work(screen always on) until the sensor captured a motion.
-
this works for me too. without formatting and reinstallation.
I’ve remove the folder node_modules and startet from 4.Thanks a lot.
-
Yes itś working …:)

very interesting, I will try it this weekend. I’m just wondering why this is not documented on any forum or website, even though you can find several users with version mismatch issues.
Great finding, @James -
hello is not working!
i have downgrade the node.js version from v6 to 5v and i dont now why i become a white screen.my pm2 logs

@samydp did you maybe reneamed this folder:
modules/MMM-PIR-Sensor/node_m odules<- is there a space in this name??
you’ll have to remove this -
I have the folder node_modules in MMM-Pir folder .
should I delete the folder? -
Can you post a printscrenn from this folder?
you can also try to go use these commands:cd ~/MagicMirror/modules/MMM-PIR-Sensor/ git pull npm rebuild -

-
That looks fine.
Did you try to remove your folder MMM-PIR-Sensor an reinstall the modul?
-
yes but i dont have the folder node_modules in the PIR Folder :/ i have install WrinPi but nothing works :/
-
ok so lets go step by step:
cd ~/MagicMirror/modules/now we will remove the PIR folder:
rm -rf MMM-PIR-Sensorand from here, we’re going to reinstall the MMM-PIR-Sensor modul:
git clone https://github.com/paviro/MMM-PIR-Sensor.git
cd MMM-PIR-Sensorrun the following cmd here:
npm installand wait, this can take a few minutes.Now you’ll have to add pi to gpio
sudo useradd -g pi gpioand reboot your Raspi:
sudo rebootYou’ll have to connect your PIR Sensor the right way with your Raspi.
I’ve connected my PIR Sensor on the following Pins:

I’ve got a Pi2 and use Pin 2 for power, Pin 6 for Ground and Pin 15 for Data.
– correctin grn pin
and dont forget to add the config :-)
-
you are the best !! i dont become no a with screen !
but the sensor dont work
i have
vcc: Pin 2
Data: Pin 7
Ground: Pin 6and my config in the config and MMM-PIR-Sensor data is:
} { module: 'MMM-PIR-Sensor', config: { sensorPIN: 7, relayPIN: false, powerSaving: true, relayOnState: 1, } },the sensetiv is max and the time is min

-
If you use pin 7 in your config its nr 4
You have to use the gpio nr.
-
Thank you it works fine !!

@Bangee I tried everything regarding the white screen issues. I’m a noob. was able to get magic mirror installed, I also installed the PIR motion detection and can confirm motion is detected.
Downgraded Node JS
Installed the electron
made sure module was added in config.jsI am using the Raspberry PI 3 mode b.
Can somebody confirm this module is working with Raspberry Pi 3.
Any help would be greatly appreciative…
Thanks.
