I made a Python script that logs temperature and progress data to MQTT and let's you publish G-code to your printer.
I've written this script to monitor my printer sensors so I can graph them in Grafana and power the printer off after some idle timeout.
There was a similar plugin available for OctoPrint, but that can't reconnect after a power cycle.
Also this one lets you send your own G-code to the printer via a MQTT message {TOPIC}/gcode.
You can install it with
pip install prusa2mqtt
And then launch it with
prusa2mqtt --help
I've only tested it under Linux where the serial port /dev/ttyACM0 persists over power cycles as long as the USB cable stays plugged in.
Let me know if it works for you under Windows or OSX.
Enjoy
