The definition of insanity is said to be:
“ doing the same thing over and over again, but expecting different results.”
What about when you don’t expect a different result but you still get one ?
Well, that’s the definition of home assistant.
I have about 30 automations defined.
Wanted to try out lovelace ui.
Copy/pasted a card from groups.yaml to ui-lovelace.yaml.
Running hassOS 1.9 / HA .75.3
The included screen captures taken in the same session
I don’t see the Lovelace missing entity in the dev-state view.
???
Lovelace says that automation.eteinde_lumiere_aqua is missing.
Your list shows no such entity - the one you highlight is automation.eteindre_eclairage_aqua.
If that’s not your problem, maybe more words and less pictures will help 
Your second word doesn’t match:
automation.eteinde_lumiere_aqua
Yet you point to (in other config)
automation.eteindre_eclairage_aqua
EDIT: I Just realized I said the same thing as @Tinkerer… my bad.
I wish HA has spell check feature
