How to Set Up Bambu Lab Printers in Home Assistant

In this tutorial, we will show you how to integrate your Bambu Lab 3D printers with Home Assistant.

Home Assistant Bambu Lab

Bambu Lab is a company that produces a series of high-quality yet affordable 3D printers.

By integrating your Bambu Lab printers with Home Assistant, you can easily view and control the status of your printers.

Using this extension, you can see almost every piece of information that the printers expose. This includes little things such as the Wi-Fi signal. You can even view and track the AMS.

By using the information this integration provides, you can perform automation that controls your 3D printer or even use this information to perform automation around your home. Or you can use it to check in on your 3D prints easily.

Over the following steps, we will walk you through integrating Bambu Labs with Home Assistant. To achieve this we will be using the Bambu Lab integration by Greg Hesp

Getting your Access Codes for Bambu Lab Integration

This section will show you how to get the values you need to set up the Bambu Labs Home Assistant integration.

In particular, it relies on the LAN access code and the Bambu Lab 3D Printer serial number. We only have a Bambu Lab X1C, so that is the only model for which we will have steps.

The exact values you require to connect locally to your printer are the following.

  • Printer Serial Number (S/N)
  • LAN Access Code
  • Device IP Address

No matter your model, the required values will be under the “Settings” screen. Where they are located within settings differs drastically between each 3D printer.

For example, on the P1P you will find the LAN code in the “Wi-Fi” menu, and the serial number at the bottom of the settings menu.

Please note that if you are using a P1P and have it connected using your LAN access code to another device already, you will only need your serial number. This is because the P1P only allows one local LAN connection. You must rely on the cloud connection if you have already used this.

Getting the Access Code and Serial on the X1C

1. On your Bambu Lab X1C, start by changing to the settings screen.

This is represented by the nut icon on the left side of the touch screen.

Open Settings on Bambu Lab X1C

2. Next, to find the serial number that the Bambu Lab Home Assistant Integration requires, change to the “General” tab.

Change to General Tab on X1C

3. Now that you are in the general tab, you will see the serial number following the “Device info” (1.) text. Write this serial number down, as you need it to connect to your Bambu Lab.

After grabbing the serial number, we must also know the IP address and LAN access code. To get these values, change to the “Network” tab (2.).

Copy Device Serial Number for Bambu Lab Home Assistant Integration

4. The final two values are located on this screen. Copy down the “Access Code” (1.) and the “IP” address (2.).

These two values are required for Home Assistant to connect to your Bambu Lab printer without needing to rely on their cloud service.

Installing and Setting Up the Bambu Labs Home Assistant Integration

This section will show you how to install and set up the Bambu Lab Home Assistant integration.

For this integration to work, you must have the access code, IP address, and serial number of your Bambu Lab printer.

Preparing Home Assistant

1. Before starting this tutorial, you must install the Home Assistant Community Store

This store allows you to easily add third-party integrations to your system, such as the Bambu Lab integration we will be using within this tutorial.

As this can be a bit of an involved process, we highly recommend following our guide on installing HACS.

2. You should now have HACS set up and ready to use. At this stage, you can continue to the next section.
