Launch of the JK-BMS RS485 add-on for Home Assistant

[jlm]

Hello!
I'm trying to set it up with an Elfin IP Gateway and I cannot get it to work.
I am confident the Elfin is connected to the JK BMS (PB2A16S30P v19) and working properly, because this alternative project (https://github.com/luisgonzalezgonzalez/jkbms_mqtt)  is successfully pulling the data from the Elfin (this is coming in from this alternative tool).
I wish to use your tool because I am going to have 4 parallel batteries soon with a master/slave.

Bonjour,
Alors vu que tu utilises une passerelle, pas besoin de modifier le  jkbms_pathpar défaut. Mais c'est pas important.

1. Peux-tu vérifier que tu es bien à la dernière version d'hier v3.3.3 C'est important, car j'ai amené beaucoup de modifications concernant les passerelles IP
   
2. Peux-tu installer et utiliser l'application serial wifi terminal pour vérifier qu'il y a bien un dialogue régulier entre le module et la passerelle
   
3. Agrandir le buffer dédié dans la configuration du Elfin. Par contre tu ne m'as pas dit si c'est un Elfin EE10 ou EW10
   
4. Le debug ne montre rien dans le log ?
   

Hello,
Since you are using a gateway, there is no need to change the default jkbms_path. But that's not important.

1. Can you check that you have the latest version from yesterday, v3.3.3? This is important because I have made a lot of changes concerning IP gateways.
   
2. Can you install and use the serial wifi terminal application to check that there is regular communication between the module and the gateway?
   
3. Enlarge the dedicated buffer in the Elfin configuration. However, you didn't tell me if it's an Elfin EE10 or EW10.
   
4. Does debugging show anything in the log?
