Moonraker Integration 1.11.0 Breaks Anycubic Kobra S1?

by SLV Team 55 views

Hey guys, have you ever encountered a situation where a software update seemingly breaks everything? I recently ran into this with the Moonraker integration for Home Assistant, specifically when updating to version 1.11.0. My Anycubic Kobra S1, which I've been happily using, suddenly lost a bunch of its sensors and controls. Don't worry, I'm here to walk you through what happened and how I troubleshooted it.

The Problem: Moonraker 1.11.0 and the Missing Sensors

My primary issue was a significant drop in functionality. After updating to Moonraker integration 1.11.0, I noticed that several crucial sensors and controls were gone. We're talking about essential stuff, like the bed and hotend temperatures, and all the controls associated with them. The fan speeds and related controls also vanished. It was like my printer had gone silent! To add insult to injury, the few sensors that were still showing up weren't even refreshing. I checked my poll rate, thinking maybe that was the problem, but everything was set up correctly. This made me suspect the update itself was the culprit.

Now, for those of you not familiar, Moonraker is a crucial piece of software in the 3D printing world. It acts as an API server, allowing you to control and monitor your 3D printer (in my case, the Anycubic Kobra S1) remotely through a web interface or, as I do, integrate it with Home Assistant. Home Assistant, in turn, allows me to create automations, monitor my prints, and generally keep tabs on things. The loss of these sensors and controls was a major setback.

I also want to emphasize here that the Creality K1C, which I also have, runs perfectly fine with version 1.11.0, but it is rooted. This highlights that this is not a general problem with 1.11.0 but a specific compatibility problem with the Anycubic Kobra S1 and its Rinkhals firmware.

To summarize, the core problem was the loss of essential printer data and control after the update. This meant I couldn't monitor or control critical functions like temperature and fan speeds, which is, well, pretty important when you're printing. So, after some quick troubleshooting, I determined that the update was at fault.

My Setup: The Players Involved

For those of you who are curious, here's a quick rundown of my setup. My Anycubic Kobra S1 is running the Rinkhals firmware, which is key because it enables Moonraker and Fluidd. I use Fluidd as my web interface to monitor and control the printer, which works perfectly. I've also got Home Assistant set up and configured to talk to my printer through the Moonraker integration.

  • Printer: Anycubic Kobra S1
  • Firmware: Rinkhals (Enables Moonraker/Fluidd)
  • Web Interface: Fluidd
  • Home Automation: Home Assistant, with the Moonraker integration. This is where I experienced the issues.

This setup had been working flawlessly until the fateful 1.11.0 update. The Creality K1C is a different beast and is not affected by this update. So, the key takeaway is that this issue is specific to the Kobra S1 with the Rinkhals firmware.

The Quick Fix: Reverting to 1.10.0

After experiencing the issues with 1.11.0, I decided to revert back to version 1.10.0. Guess what? Everything worked perfectly again! All the missing sensors and controls returned, and my printer was back to reporting and responding as expected. This was a clear sign that the issue was with the 1.11.0 update and not with my printer or my Home Assistant configuration.

The Solution: Downgrading the Moonraker integration to the previous version, 1.10.0, immediately resolved the problem. This confirmed that the update itself introduced a compatibility issue with the Kobra S1 and its Rinkhals firmware.

I'm now waiting to update the integration to see if a newer version might address the issue. The main purpose of this article is to share this experience and potentially help others who might run into a similar problem. I'm hoping that a minor change or obvious change was introduced from 1.10.0 to 1.11.0 that caused this.

Troubleshooting Steps and Logs

I didn't want to leave you hanging without some suggestions, so here's what I did in terms of troubleshooting:

  • Verified the Moonraker Integration Version: Checked the version of the Moonraker integration in Home Assistant (HACS). Made sure it was indeed the updated version (1.11.0 initially, then verified the downgrade to 1.10.0).
  • Checked Printer and Moonraker Logs: Since I could still use Fluidd, the printer itself was working fine. The issue was with the sensors and controls within Home Assistant. I knew the issue was not with the printer itself. I wanted to see if there were any error messages in the logs that might indicate what went wrong, but there were no relevant errors.
  • Reverted to an Older Version: After confirming the issue, I reverted to the previous version and everything worked again.

Next Steps and Future Updates

Since downgrading to 1.10.0 resolved the issues, I'm now taking a
