Since the 2025.6 update, and the subsequent deprecation of the core and supervised installation methods, I decided to migrate my current home assistant setup from the supervised installation method, to the container installation method. As suggested in https://www.home-assistant.io/blog/2025/05/22/deprecating-core-and-supervised-installation-methods-and-32-bit-systems/#how-to-migrate, I made a backup, downloaded said backup, then restored it during the initialization of the new system.
This has worked great, with the exception of the backup integration. When checking the integration in the Integrations, it shows a yellow warning triangle with an exclamation sign, and text indicating it is not loaded. Clicking the integration and then "ADD SERVICE" will result in the following error message:
This integration cannot be added from the UI
You can add this integration by adding it to your 'configuration.yaml'. See the documentation for more information.
I did as a matter of fact check configuration.yaml, but I don't see any relevant section there and I'm hesitant to just randomly starting to edit the yaml when the documentation indicates this should be possible to edit from the UI.
