The PrusaLink integration allows you to monitor your Prusa 3D printer and its progress with your Home Assistant installation. This integration is currently limited to the Prusa Mini.
Adding PrusaLink to your Home Assistant instance can be done via the user interface, by using this My button:
PrusaLink can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.
If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:
Browse to your Home Assistant instance.
In the sidebar, select Settings.
From the configuration menu, select Devices & Services.
In the bottom right, select the Add Integration button.
From the list, search and select PrusaLink.
Follow the instructions on screen to complete the setup.
To obtain the API key, on your printer navigate to Settings -> Network -> PrusaLink. It will then be shown at the bottom of the screen.
This integration requires PrusaLink v2. If you have the Prusa MINI, you need to run firmware 4.4.0 or later.
