A small python script that controls the display of a MagicMirror independent from the MagicMirror application. It turns off the display when a given amount of time has elapsed after the last motion has been recognized.
Basically it can control any display connected to a Raspberry Pi which has Raspbian installed.
I added a systemd service file to use it as systemd service and start it at boot time.
Clone the repository to wherever you want:
git clone https://github.com/deg0nz/MagicMirror-Display-Controller
If you want it started as a systemd service, you have to copy the .service file to /lib/systemd/system and reload the systemd daemons.
Here's an example of the commands needed (cwd is the repository):
cp ./pir_sensor.service /lib/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable pir_sensor.service
sudo systemctl start pir_sensor.service
If you cloned the repository somewhere else than your home directory, you have to change line 7 to the location of the pir.py file like this:
ExecStart=/usr/bin/python -u /path/to/pir.py
Line 7 defaults to /home/pi/MagicMirror-Display-Controller/pir.py. So if you cloned the repository to your home folder, you don't have to change anything.
You can see the logs with journalctl -u pir_sensor.service
You can configure the amount of the countdown time via the timeUntilDisplayOff variable. The value is given in seconds.
The pin variable should be set to the connected data pin of the PIR sensor. Default is 14.
