Lancement du module complémentaire JK-BMS RS485 pour Home Assistant

[j_ofen]

Bonjour,

Excellent add-on que je découvre et que je suis en train d'implémenter dans mon home assistant.
Toutefois, je suis en difficulté pour le paramétrage. Vous pourrez peut-être m'aider.

Je cherche à connecter mon JK-BMS à mon instance Home Assistant en RS485 <> NB114 <> ETHERNET.
La configuration de l'interface semble correcte (je parviens à lire des datas avec Modbus Poll).

ça se corse sous Home Assistant. Voici les symptômes :
- aucun JK-BMS n'est visible dans MQTT explorer
- quels que soient mes paramètres de configuration, Coud Broker est actif dans les logs (avec un id qui n'est pas le mien, donc un doublon et une coupure connexion - j'ai pourtant paramétré sur false cette fonction)
- comme un chemin de port série est obligatoire, j'ai également essayé avec et sans interface RS485<>USB branchée.

Ci-dessous une coupe du journal.
D'avance, merci pour votre appui.
