A Home Assistant Integration for Bambu Lab printers.
Want to contribute to ha-bambulab? Great! We have a few small asks though!
- Please create your patch pull requests against the
mainbranch. - Please be verbose in your description of your changes in your pull requests.
If you feel this integration was valuable and want to support it in other ways, you can buy me a coffee.
To install this integration, add this GitHub Repo to the HACS Custom Repositories, or click the badge above.
For configuration, you'll ideally use your Bambu Credentials for the simplest setup and the most features as some sensors are supported by data from your Bambu cloud account print history. You can also, optionally, provide the printer's local IP address to enable the more efficient and reliable direct to printer connection for the printer sensor data and to enable the P1/A1 chamber image support.
However, the Bambu cloud connection doesn't support 2FA and passwordless social media accounts at this time. And it obviously does not support printers explicitly set to Lan Only Mode. If you fall into any of these categories, select the Lan Mode Configuration connection option. You will need to manually provide:
- Printer Serial Number - can be found in the printer settings or in Bambu Studio.
- Local printer IP address - can be found in the printer network settings (LAN).
- Access Code - can be found in the Printer settings.
If you signed up using any OAuth method, you need to set a password for your Bambu Cloud account:
- Login to the Bambu mobile app using OAuth.
- Tap the person icon at the bottom right.
- Tap Account Security > Change Password.
This will allow you to set a password. Now you can login to the HA integration using your Bambu username and password instead of OAuth.

| Total Usage Hours | * See Note |
* This is a running estimate that will be imprecise. Starting hours can be read of the printer screen and provided during initial printer setup or updated later via the configuration flow. And the integration must be running when a print completes to update the value. For non-X1 printers, if the integration is restarted mid-print and Bambu cloud connection isn't setup, the usage hours will not be added as print start time won't be known. It's expected that you'll need to adjust this value occasionally to fix drift from the value the printer itself calculates.

This integration implements a handful of device triggers to make some common automation scenarios a little easier. See device triggers.
- Send Command: Sends arbitrary GCODE to the printer. Be careful as it does not check if the printer is running a job or not so before invoking this action, you should check the printer state to ensure it is not running a job.
You can find an amazing web configurator to easily create a Dashboard for your Bambu printer like the one below at https://www.wolfwithsword.com/bambulab-home-assistant-dashboard/.
If you run into any issues, we now have built in diagnostics. To grab the latest information, hit the "Force Refresh Data" button under the Diagnostic section.
Then on the device info page for the printer entity, you will see a "Download Diagnostics" button. Make sure you upload this to your Bug ticket/GitHub issue.
When logging a bug, always ensure you send us the debug logs.
If you are hitting issues during initial integration setup, you will need to enable logs in your configuration.yaml file by adding the following and restarting Home Assistant:
logger:
default: info
logs:
custom_components.bambu_lab: debug
If you have previously successfully installed the integration, debug logs can be enabled from the integration page within Home Assistant:
The debug logs will appear in the standard Home Assistant logs.
