Yes, you can monitor and control your 3D printer from anywhere by connecting OctoPrint or Moonraker to Home Assistant . Both print servers expose APIs that Home Assistant can poll for real-time data - print progress, temperatures, camera feeds, error states - and from there you can build dashboards, fire notifications on your phone when a print finishes, detect failures with AI-powered camera analysis, and even kill power to a runaway printer through a smart plug. The whole setup takes about an hour once you have a print server running on a Raspberry Pi, and the result is a 3D printer that behaves like any other smart device in your home.
