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

bibi

@yawns thx! :))

strawberry 3.141

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

bibi

@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 :

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 ?
