PrusaLink
prusalink
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/MINI+, Prusa MK3.9/MK4, Prusa XL, Prusa CORE One, and with the older Raspberry Pi-based Prusa MK2.5/MK3.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
camera | Camera | Needs its own HomeKit Bridge in accessory mode |
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (temperature) | |
button | Button (as a switch) |
What people report
