Failed to load setup wizard:500 Internal Server Error Server got itself in trouble

Has this happened again?
What version of HA?
What version of the integration?
Try the latest beta, which contains a lot of minor fixes

This happened again and again
HA v. 2026.1.3
Trying last release, and today latest beta, but nothing helps

What setup wizard are you guys talking about? What exactly are you doing? You need to provide more info.

The "setup wizard" is the config flow dialog that appears when you add the integration via Settings > Devices & Services > Add Integration.

The 500 Internal Server Error - Server got itself in trouble message comes from the OpenPlantbook API server (open.plantbook.io) itself - it is not a bug in the integration. During setup, the integration calls the API to validate your credentials, and if the API server returns a 500 error, that gets shown in the dialog.

This typically means the API server was temporarily having issues when you tried to set up the integration.

Could you please:

1. Confirm you can access https://open.plantbook.io in a browser
2. Try setting up the integration again - the server issue may have been temporary
3. If it still fails, add this to your configuration.yaml and provide the logs after a failed attempt:

logger:
  logs:
    custom_components.openplantbook: debug

After enabling "API-Key Authentication (For Developers Only)" in https://open.plantbook.io/ integration successfully setup. Thank you
