Present an Elgato Stream Deck as a Homie MQTT device
You can specify the MQTT host and port using a file named config.json. This should specify two fields: mqtt_host and mqtt_port. For example:
{
"mqtt_host": "localhost",
"mqtt_port": 1883
}
The program will try to load a PNG image for each key from the current working directory. The images should be named simply <key number>.png,
with the first key (top left) being key 0.
A systemd unit file is provided if you wish to install it as a systemd service.
You will need to edit the WorkingDirectory= line in the file and then copy it into /etc/systemd/system. Once you've done that, you can run the following:
systemctl refresh-daemon
systemctl enable --now homie-streamdeck.service
Alternatively, a Docker image of this is available on Docker Hub.
