If i go to Customizations and select an entity I get this message:
It seems that your configuration.yaml doesn’t properly include customize.yaml.
Changes made here are written in it, but will not be applied after a configuration reload unless the include is in place.
and this one (because it is set like it stays)
The following attributes are already set in customize.yaml
When I add a friendly_name it looks like it is working, but just until reboot.
It also looks like when I set friendly_name is it actually the name attribute that is changed.
Not sure if that is the best solution but it almost works.
If I add something in the UI it does not get indented correctly in the file, but I usually just use the yaml anyways…
