It appears Home Assistant’s official PrusaLink integration is not yet compatible with the PrusaLink API shipped with a MK4 printer. This project was put together as a temp solution to fix my existing automations requiring various metrics from the Printer’s API.

Wait. You’re telling me I can connect home assistant to my printer in since way… I’ve been missing out.
If you are using OctoPrint there is also a Home Assistant integration for that.
Same with MainsailOS/Klipper. It’s been great being able to view my PiCam from anywhere to see how the print is doing. Now I just need a reliable lighting solution.
My most important automation is turning on my exhaust if the temp starts to rise on the bed or nozzle.
