Connect your JK-BMS in Home Assistant wired with an RS485 & CAN adaptator

Published at : 18 Dec 2025

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

You can install it from: https://github.com/jean-luc1203/jkbms-rs485-addon

Main features :
Multi-BMS compatibility: simultaneous support for multiple JKong models (PBA16S20P, PB2A16S15P, PB1A16S15P, PB1A16S10P) connected to a single RS485 or CAN 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. [Image: githubbutton_sm.svg]

Easy installation: add the GitHub repository, install via the add-on store, configure the main settings and the module is up and running in minutes..
