Bonjour,

j'ai mi à jour Proxmox en 9.2.20 à la place 9.2.11 et depuis HA fonctionne plus correctement.

Quelqu'un aurait une piste de dépannage ?  
Étrangement l'heure ne correspond pas à la coupure pour mise à jour.

Sans doute rien à voir avec la mise à jour de Proxmox si ce n'est un redémarrage de HA ...

Tu as un souci dans ton fichier `sensor.yaml` qui doit dans doute être inclus dans `configuration.yaml`

```auto

```

Oui, j'ai regardé l'erreur. J'ai impression qu'il bloque sur un accent. Je vais l'enlever.  
Sinon pour le reste j'ai pris une sauvegarde de deux avant et c'est reparti.  
C'est vraiment très étrange.  
Merci

Dans les outils de développement il y'a un outil de vérification de syntaxe du fichier de configuration yaml pour éviter ce genre de désagrément
