If you have created an entity manually in Home Assistant, you might have seen the message “This entity (‘abcde.fghi‘) does not have a unique ID, therefore its settings cannot be managed from the UI. See the documentation for more detail. Some entities can’t be fixed, but you can fix some. Like for example light groups.
If you create a light group in configuration.yaml, you might see this message. But, rest assured, there is a simple solution. Just add the “unique_id:” attribute to the group, and you have solved this issue.
To create a unique id, you can use an online tool like uuidgenerator.
