mqtt-monitor-switch

Control the power state of a RPi monitor via MQTT

This requires Paho MQTT to be installed, eg. pip install paho-mqtt

Edit the file to add your broker address, password, etc.

It uses the tvservice and some other hackery to make a HDMI attached monitor sleep/wake in response to MQTT commands.

I use this on a dashboard monitor in my kitchen, so that OpenHAB can switch the dashboard on/off in response to movement from the motion sensor, presence detection, time of day, etc.

If you want the script to run automatically at startup:

1. Copy the service file to /lib/systemd/system/
2. sudo chmod 644 /lib/systemd/system/mon-mqtt.service
3. sudo systemctl daemon-reload
4. sudo systemctl enable myscript.service
5. sudo reboot
6. After reboot use sudo systemctl status mon-mqtt.service to check if it's running
