A Integration for Home Assistant and Elegoo Printers using SDCP
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 |
|---|---|---|
light | Light | |
fan | Fan | |
camera | Camera | Needs its own HomeKit Bridge in accessory mode |
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (temperature, humidity, air quality…) | |
button | Button (as a switch) | |
select | Mode picker (as switches) |
What people report
Elegoo resin and FDM printers (Mars, Saturn, Centauri Carbon) work over the local network and MQTT. Centauri Carbon 2 needs LAN Only Mode and has had camera hiccups.

Please describe. After installing the Canvas unit on the Centauri Carbon (1) and changing the toggle Canvas/AMS installed on this extension's configuration, new fields were shown, such as A(1-4) Attributes, Color, Name and Active Filament Color, but there is no current tray id. ### Describe the solution you'd like Adding a current tray id would be very helpful for a better spoolman integration, as you could have a helper field with the spool for each tray, and update the usage based … Excerpt saved from GitHub on 2026-10-23. | Issue #395 · 2026-07 | |
