Bambu Lab X1 X1C MQTT

Configuration
206

Sure! The current full way we’ve come up with here goes as follows:

  1. Requirements/Assumptions
    • Home Assistant is setup
    • MQTT broker setup and connected to homeassistant
    • Node Red ready to use
2) NodeRed Setup
  • NodeRed Palette Requirements
    • I think none for just the base flow. Let me know if this isn’t the case.
  • Download the first file from here bambu-mqtt.json Node-RED Flow - BambuLab X1 MQTT Relay for Home Assistant MQTT Auto-Discovery · GitHub
  • Open it up in a text editor such as NP++ and get ready to do some replace-alls
    • The top comment of the gist link has the information you need for replacing. Anytime I update this gist, replacements for that main flow will be edited in that comment, and I will always comment with changes down below linked to a revision number.
  • Once all is replaced, import the JSON into NodeRed (top right hamburger menu → Import)
  • If your MQTT server for HA has any credentials, you will need to edit them.
    • Click on any pinkish/purple MQTT node that is for HomeAssistant (Name probably contains it)
    • In the edit for that node, click the edit icon next to the “server”, then enter credentials in the new window, save and close.

I suggest ignoring the second json file in the gist for now, that is for a more complex setup I have that requires PostgresDB, and/or setting up the FTP server connection, hosting an HTTP endpoint etc, and requires more palettes.

3) HomeAssistant Setup

  • Requirements

    • MQTT is connected
    • If you have the node red flow setup, and the printer is ON, then go to the devices/integrations tab, MQTT, then you should see your printer and all attached AMS units as separate devices if everything is working.

  • Dashboard Yaml

    • Requirements
      • HACS repos
        • card-mod
        • lovelace-layout-card
        • hui-element
        • button-card
        • mushroom
        • config-template-card
        • FontAwesome Icons (to load custom_icons)
        • custom-ui* (Maybe, I can’t remember)
      • Device Requirements
        • Smart Plug/Switch printer is connected to (if not, then can edit the yaml to remove)
    • Download this yaml from the gist Bambu X1C + NodeRed HomeAssistant YAML Snippet · GitHub
      • More replacements to do, marked in a comment a bit lower down, but essentially just {PRINTER_NAME}. Replace all cases of it with the LowerCase version of your printer name like in the nodered json. This is for the sensor/entity naming.
      • Find {PREVIEW_URL} and remove it + the picture hui-element it’s in. This is only if you have the advanced FTP stuff setup with the second flow.
      • Go to the third comment in the gist and download each of the attached images of the AMS and X1C. Save them in the locations in homeassistant mentioned in the comment. (/local/media is /config/www/media for HA structure)
      • Create a folder in your homeassistant config called custom_icons (right next to custom_components) and copy this SVG into it. Rename it to filament-1.svg.
    • If you have a smart plug for the printer, change the sensor entity to it (replace switch.bambu_printer)

Then just copy and paste the yaml into a new dashboard. Also restart home-assistant after putting in the custom SVG icon. I put the dashboard into a grid layout custom layout dashboard myself, but it’s up to you for any customizing!
