The PrusaLink integration allows you to monitor your Prusa 3D printer and its progress with your Home Assistant installation. This integration works with Prusa MINI and Prusa MK4. This integration requires PrusaLink v2. If you have the Prusa MINI, you need to run firmware 4.4.0 or later.
When adding the integration, you will be asked to provide a hostA device that participates in your network. If asked for the host, enter either the device’s IP address or host name. If you don’t know those, check the list of hosts in your router.

To obtain the host name and API key/password:
- On your printer, navigate to Settings > Network > PrusaLink.
- Find the device’s IP address. Alternatively, you can look for the printer’s IP address or hostname on your router.
- Depending on your model, the entry may not be called API key, but Password.
