Turn on/off the display output of a Raspberry Pi via MQTT. Works with HomeAssistant MQTT Autodiscovery.
This can be used (for example) to turn on/off the screen attached to a Raspberry Pi running Grafana in kiosk mode via a motion detector.
Add the MQTT credentials and the device name to config.ini.
Install the Package vcgencmd on your Raspberry Pi (if not available already) to control the screen:
sudo apt-get install vcgencmd
After that you have to install the python dependencies using pip:
pip install -r requirements.txt
Run main.py with python3. An example systemd unit is provided to run this script as a service.
If everything works correctly, a switch with the configured device name should pop up in your Home Assistant instance.
