I see this confusion come up over and over for new users. I’m willing to do a PR if we can figure out more/better wording. To start with, what do you think of just adding a second sentence?
“This entity does not have a unique ID, therefore its settings cannot be managed from the UI. This is usually because the entity is defined in configuration.yaml, and settings for such entities must also be done in yaml.”
It’d be nice to have something shorter, but I couldn’t come up with anything.
