Connection impossible via SerialServer

[bagl3y]

Bonjour,

J'utilise SerialServer pour me connecter à mon module TIC via le réseau.

Quand je tape mon url : rfc2217://192.168.42.239:2217 , j'ai une erreur : Erreur inattendue

Coté Logs HA, j'ai une error suivi d'une stacktrace :

Essayé avec la version 2.0.7 et 3.0.0-beta4

Bonjour, il s'agit bien d'un bug de l'intégration, qui n'affecte à priori que l'utilisation via rfc2217

L'implémentation rfc2217 de pyserial utilise des appels bloquants à sleep, qui est empêché par HomeAssistant si appelé depuis la boucle d'évènement principale. L'intégration utilise un thread séparé mais l'initialisation de la communication au démarrage et le test de connexion lors de l'ajout d'un appareil ne s'exécute pas dans le contexte de ce thread.

Je travaille sur le correctif

[tomleglaunec]

La pre-release 3.0.0-beta4 3.0.0-beta5 ne devrait plus présenter le problème, j'attends vos retours

You probably mean 3.0.0-beta5 ;)

Works for me thanks!
