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. Check out the help at http://commonmark.org/help/ - scroll down to see the various options for using backticks.

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 -

@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
