Not sure if this is the right place for this, but I’ve spotted it a few times and never though it worth posting as a bug as it doesn’t actually stop anything from working. But, whever I use Configuration > Customizations to add a friendly name to an entity which doesn’t have one by doing the following:
- Select entity from list
- Select Other from pick an attribute to override
- Enter friendly_name as the attribute name and the friendly name as the value
This error appears:
The friendly name does get set successfully and, after reloading the page, the error goes away. So it only appears to be an issue when adding a friendly name to an entity without one. The friendly name can be updated without the error message and other attributes can be added with this error.
I wonder if it is something to do with the list of entities being displayed based on their friendly names and adding a friendly name after the list was populated is somehow confusing it?
Edit: And customize.yaml is defintely included properly (this error doesn’t display until I add the friendly name)
homeassistant:
...other stuff...
customize: !include customize.yaml
