MMM-PIR-Sensor black screen

@Stef with the black screen and a keyboard, press ctrl-shift-i (letter I),
to open the developers console, select the console tab, and scroll up to find errors, red text

@sdetweil thanks for the headsup - but this does not work… i see the mous coursor though, but that’s it.
I even can’t “cancel” the fullscreen mode of the magic mirror by pressing F11 (usually this brings me back to the desktop) :/

I did a little research and stumbled over severall issues on the github page - this one catched my eye, but didn’t brought me any luck…

So, what did i do excatly?

1. Install:

cd ~/MagicMirror/modules/
git clone https://github.com/paviro/MMM-PIR-Sensor.git
npm install
sudo usermod -a -G gpio pi
sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt
sudo reboot

2. New wiringPI version:

sudo apt-get purge wiringpi
hash -r
sudo apt-get install git-core
cd
git clone git://git.drogon.net/wiringPi
cd ~/wiringPi
git pull origin
./build
sudo reboot

3. reinstall EPOLL:

cd ~/MagicMirror/modules/
sudo npm install --save-dev electron-rebuild ./node_modules/.bin/electron-rebuild

4. recompile Electron:

npm list | grep electron
cd ~/MagicMirror/modules/MMM-PIR-Sensor
npm rebuild --runtime=electron --target=1.4.5 --disturl=https://atom.io/download/atom-shell --abi=50
sudo reboot

Expectation: It Works now…
Reality: It does not…

my Config is:

{
          module: 'MMM-PIR-Sensor',
          config: {
                       sensorPin: 23,
                       powerSaving: true,
                       powerSavingDelay: 120 // 2 Minutes
                       }
},

I just excluded this part of my config - and my mirror displays everything again…

Andy ideas left? :)

Hey all,
turns out, that the MMM-PIR-Sensor Module is buggy - well, at least for me.
Can’t get it to work, but i found an alternative: MagicMirror-Display-Controller

Works like a Charme!

Case closed :)

Have a nice weekend!

@Stef Hi, yesterday i added two Modules to the Showcase Area. On that monitors GPIO Pins and one which controls the Monitor.
My usecase is exactly like yours. I use an PIR sensor to detect user presence and want the screen to be turned off after a configurable timeout.
If you want to try them:
MMM-Screen-Powersave-Notification
and
MMM-GPIO-Notifications
