MMM-PIR-Sensor (black screen)

Stabber

Hello,
I have a problem with (I think) the PIR-Sensor module. It works fine, when the mirror wakes after 10-15 min up. But when the pause is longer (a few hours) I have a black screen with the cursor on it. I can’t see any modules and need to restart the Mirror. Do someone know how to fix it?

@Stabber what is in your config.js for the module?

		{
			module: 'MMM-PIR-Sensor',
			config: {
				sensorPIN: 4,
				powerSavingDelay: 25,
			}
		},

Hi,
I’ve a similar Problem with MMM-PIR-Sensor. However, my MagicMirror already starts with a black screen as soon as I insert the module. The config is almost identical.

Hey,

I’ve had the same problem and I solved it with Crontab and Python. The Module from paviro made some trouble with my mirror.

@conkhidot Hi, do you maybe have some links or could give instructions how to do it? I would be grateful.

was this solved?
i just installed everything from this tutorial: https://howchoo.com/g/ntcymzbimjv/how-to-install-magic-mirror-on-your-raspberry-pi
everything works EXCEPT this pir module. once i remove the module, off course everything is back to “normal”

but if i add the module back in with

{
			module: 'MMM-PIR-Sensor',
			config: {
				sensorPIN: 4,
				powerSavingDelay: 25,
			}
},

i get nothing but a mouse cursor and a totally black screen. it doesnt turn off or on via the PIR either.

never mind…
i got it now. i reinstalled everything again.
cd ~/MagicMirror/modules
git clone https://github.com/paviro/MMM-PIR-Sensor.git
cd MMM-PIR-Sensor
npm install

sudo usermod -a -G gpio pi

sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt
to allow turning on/off the hdmi output.

sudo reboot

sudo nano ~/MagicMirror/config/config.js


                {
                        module: 'MMM-PIR-Sensor',
                        config: {
                                sensorPIN: "4",
                                powerSavingDelay: "25",
                        }
                },
