3D printers have long been popular in the maker community and with those that create their own electronics projects. Thus, it is no surprise that OctoPrint has been integrated with Home Assistant for a long time. In fact, the integration first appeared in Home Assistant 0.19. With the recently released 4.4.0 Firmware for Original Prusa MINI/MINI+ you can now skip OctoPrint altogether and integrate Prusa Research's smallest offering directly using PrusaLink v2.
This integration couldn't come at a better time, seeing as Raspberry Pis, which are generally used to run OctoPrint, are still as rare as hen's teeth. All that is needed to bring the Original Prusa MINI/MINI+ on to your network is an ESP-01 or ESP-01S (the latter is largely recommended) and a short amount of spare time.
