Kobra X LAN for Home Assistant

Home Assistant integration for monitoring and controlling an Anycubic Kobra X through KX-Bridge.

This project was coded with AI assistance and should be reviewed before use in production.

Architecture:

• printer <-> KX-Bridge <-> this integration <-> Home Assistant

Requirements

• Running and reachable KX-Bridge-Release
• Bridge endpoint accessible from Home Assistant at http://<bridge-host>:7125

Installation

Option 1: HACS

1. In HACS, add this repository as a custom repository (category: Integration): https://github.com/gangoke/kobrax-lan-hass-component
2. Install Kobra X LAN from HACS.
3. Restart Home Assistant.
4. Go to Settings -> Devices & Services -> Add Integration.
5. Search for Kobra X LAN.

Option 2: Manual (local custom_components)

1. Copy the kobrax_lan folder into your Home Assistant custom_components directory: <config>/custom_components/kobrax_lan
2. Restart Home Assistant.
3. Add Kobra X LAN from Settings -> Devices & Services.

Configuration

The config flow asks for:

• Host: KX-Bridge host and port (example: 192.168.1.50:7125)
• Printer name: Friendly display name in Home Assistant

Notes

• This integration communicates with KX-Bridge HTTP endpoints and does not connect directly to the printer.
• Keep KX-Bridge and Home Assistant on a trusted local network.
• Camera streaming prefers the bridge H.264 endpoint (/api/camera/h264, MPEG-TS passthrough) on newer bridge releases, with RTSP/MJPEG fallback for older releases.
• Native WebRTC is not implemented. For WebRTC in Home Assistant, point go2rtc (or another WebRTC-capable add-on) to the camera source you prefer (H.264 bridge endpoint or RTSP).
