Note

Anycubic have been attempting to block MQTT access, see here

I'm moving on to another printer brand and won't be active on this project as much but will still be fixing issues.

MQTT access is now available using Slicer Next (windows version) tokens.

Still works as of 01/12/2024.

Anycubic Cloud Home Assistant Integration

Component is working very well so far with:

• Kobra 3 Combo
• Kobra 2
• Kobra 2 Max
• Kobra 2 Pro
• Photon Mono M5s (Basic support still)
• M7 Pro (Basic support still)

If you have success with other printers please report it, or if you don't please report that too :)

Anycubic Cloud is polled for data updates every 1 minute, whilst MQTT updates can be received multiple times per second.

If you find updates for any sensors are only received every minute, please open an issue.

How to Install

1. Pick a method of authentication and grab your logon token.
2. Add this repository to HACS under ... (menu) > Custom Repositories as an Integration
3. Restart Home Assistant
4. Go to Settings > Integrations > Add New and search Anycubic
5. Select your chosen authentication mode
6. Paste your token into the User Token or Slicer Access Token box.
7. Select your printer, then you're good to go!
8. Optionally configure more options in the home assistant integration configure menus.

Slicer authentication

Important

Only tested / supported with Slicer Next for Windows

1. Make sure your installation of Slicer Next is logged in, then close it.
2. Locate your AnycubicSlicerNext config directory.

Note

This is found in:

%AppData%\AnycubicSlicerNext\AnycubicSlicerNext.conf

or

C:\Users\<USERNAME>\AppData\Roaming\AnycubicSlicerNext\AnycubicSlicerNext.conf

3. Copy/save the whole access_token string without the quotes, it should be a 344 character string.
4. Ideally you should now clear your login config for the slicer to prevent it logging in at the same time as Home Assistant. This can be done setting your access_token to an empty string in the config file, e.g. "access_token": "",

Web authentication

Important

Unfortunately web authentication no longer supports MQTT updates.

1. Go to the Anycubic Cloud Website
2. Log in
3. Open Developer Tools in your browser
4. Paste window.localStorage["XX-Token"] into the console
5. Copy/save the long string of numbers and letters without the '' - this is your token.

Re-Authentication

If you log yourself out or your token expires you'll get a re-authentication warning in Home Assistant, just grab a new token as above.

Thanks

Thanks to @dangreco for his original work on threedy which I first modded and then completely rewrote with Lit instead of React.
