MMM-PIR-Sensor - White Screen

yawns · Oct 26, 2016, 3:34 PM

Everything with at least one tab indent is treated as code and highlighted. ;)

@yawns thx! :))

@bibi you forgot to close the config section in the newsfeed module, add } after showPublishDate: true and you should be fine

bibi · Oct 26, 2016, 8:07 PM

@strawberry-3.141 yeah! thx a lot. at least i can see this white screen now :p :))) have to figure out how to solve this… Only if it’s realllllly really obvious for you/someone, i post my log file. (sorry to ask so much) otherwise not prob, i will reinstall the PIR module…

Ok the problem it’s solved! except the screen is turning on and off in a very strange way… have to figure out why.

For those you would get the same issue as me, what i did after fixing my config file was:

sudo apt-get update & upgrade & reboot,
go in MMM-PIR-Sensor folder in modules folder and run npm install there
3.sudo reboot
cheers

Also had the “white screen” problem. I installed a complete new Raspian (with PIXEL), a new MagicMirror - including node.js in version 7.3.0
As soon as i tried to get the MMM-Pir-Sensor working, it failed (with an white screen). Heres, how i solved my problem.

At first: Theres no need to downgrade the node (i tried this too, and had no luck)

I figured out, that my problem was an MMM-PIR-Sensor installation error i did not recognized at the beginning. When i tried “npm install” i got something like this (an error):

"gyp WARN EACCES user “root” does not have permission to access the dev dir “/root/.node-gyp/5.12.0”

I figured out, that there are two ways of solving this:

CHOWN the directory the install procedure tries to install
use “npm install --unsafe-perm”

Im aware that option two is not the “elegant” way, but it solved my problem (and i did not have to change directory permissions).

I removed all files and git the files again (like described some lines above from banglee) and then just use “npm install --unsafe-perm”

The “–unsafe-perm” option was the key to my problem…

Hi @Medo ,
I have gotten the white screen problem as well and my raspberry pi configuration is similar to yours ( running on PIXEL with the latest nodejs).

However, upon using option 2 from your solution. I have obtained this error :

@zichao92

First things that come to my mind:

maybe a “sudo” is missing? Like sudo npm install --unsafe-perm?
are you executing this from the MMM-PIR-Sensor directory ?

zichao92 · Jan 2, 2017, 11:22 AM

Hi @Medo, Thanks for the reply.
1.) I tried this method and it gives an output of the following error.

Yea it’s in the file directory ( MagicMirror/modules/MMM-PIR_Sensor )

@zichao92
What i also did, was a complete reinstall of the PIR-Sensor

I followed the steps, “Banglee” described some lines above:

ok so lets go step by step:
cd ~/MagicMirror/modules/

now we will remove the PIR folder:
rm -rf MMM-PIR-Sensor

and 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-Sensor

run the following cmd here:
npm install and wait, this can take a few minutes.

Now you’ll have to add pi to gpio
sudo useradd -g pi gpio

and reboot your Raspi:
sudo reboot

Sorry, no further ideas so far (maybe you can open a PIR-Sensor troubleshooting thread)?
