Grocy integration issue(not addon)

[malosaaa]

Describe the bug

So grocy itself works, but the problem is in devices its not loaded, when i try to reload i get that error.

After upgrading Home Assistant OS from 2025.3.3 to 2025.4.1, the Grocy integration fails to set up and throws a JSONDecodeError.

⸻

Expected behavior

Grocy integration should load normally without errors upon system startup or reload.

Full traceback available above — appears to fail while trying to retrieve system config from Grocy via pygrocy2.

⸻

Installed versions
• Home Assistant OS: 2025.4.1
• Grocy: 0.24.0
• Grocy integration: (custom component)

⸻

How is Grocy installed?
Installed via Home Assistant Add-on.

⸻

Additional context
This was working fine before the upgrade. The error started immediately after updating to HA 2025.4.1. Seems like Grocy API is returning an empty or invalid response when queried for system config.

Same thing happens to me. Integration randomly fails to initialize, after reloading it a couple of times it eventually loads.

This occurs intermittently, impossible to predict when it will happen next.

I cannot even install the integration(not the addon). I'm able to logon and use the AddOn ok. But after I create the API key and try and add the integration I get a similar error as above. I've tried using the HA URL, local IP Address, ingress address, and the docked container address. All give an error. Just says something went wrong in the UI but the logs are pretty much identical. I'd like to have the entities to be able to pull into scripts and automations. Let me know if there is anything I can do to assist.

Integration for me seems to fail to load almost every time on system restart. Usually works after restarting the integration. Also happy to provide further info if helpful
