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

[jlm]

    I am pleased to announce the release of a new Home Assistant add-on dedicated to managing JKong BMSs via a wired RS485 connection.

And as usual, it remains free of charge.          (The source code is available on the Github)

   

This module allows you to supervise and centralize the monitoring of several JK-BMS (up to 15) directly from your Home Assistant installation.
This can be done without the need for multiple specific hardware modules. Only RJ45 cables are required.


Main features :

• Multi-BMS compatibility: simultaneous support for multiple JKong models (PBA16S20P, PB2A16S15P, PB1A16S15P, PB1A16S10P) connected to a single RS485 bus.
  

• Seamless integration with Home Assistant: simple configuration via the interface with automatic creation of entities for each BMS in Home Assistant
  

• MQTT interoperability: all collected data is published on an MQTT broker (of your choice), allowing it to be used in other home automation solutions such as Jeedom.
  

• Preconfigured dashboards: Two ready-to-import dashboards are available for quickly viewing essential information without having to go through a long and tedious configuration process. A contribution is requested for these.  
  

• Easy installation: add the GitHub repository, install via the add-on store, configure the main settings (USB port, number of BMS, MQTT access), and the module is up and running in minutes..
  

Distinctive features:
Unlike current solutions that require one ESP32 module per BMS, this module allows centralized, wired management of all your JKong BMSs from a single Home Assistant add-on, for simpler and more reliable installation.

Recommended use:
This module is intended for all users who wish to effectively monitor multiple JKong BMSs in a Home Assistant environment, while limiting hardware and prioritizing the stability of the RS485 connection.
