BMS JK Grafana dashboard

Tableau de bord énergie temps réel sur écran tactile 800×480 — ESP32-S3, solaire, batterie, routeur, Home Assistant

ESP32 touchscreen controller & dashboard for JK-BMS battery packs — live monitoring, settings & MOSFET control over RS485, 12-language UI, Home Assistant (MQTT), built-in web app + OTA, and a no-hardware Web Bluetooth dashboard.

Adaption to use mqtt to control your Inverter via CAN

Passive multi-pack JK BMS RS485 bridge for Home Assistant

This is how JK-BMS UART can be read.

ESPHome component that spoofs a ghost JK BMS battery on RS485, so real packs can actually reach 100% and reset their coulomb counter instead of the inverter stopping charging early on drifted SoC.

One-shot JK-BMS BLE poller in Go — scans, connects, reads one JK02_32S cell-info frame, writes JSON, exits. For Pi/Linux + Home Assistant.

Raspberry Pi + Node-RED suite: reverse-engineered RS485 (Deye/Pylontech style) plus JK-BMS BLE->MQTT gateway for LiFePO4 BMS (PAPOOL/DR48100 etc.).

This ioBroker adapter integrates PACE BMS, JK BMS, and TDT BMS into ioBroker, allowing real-time monitoring of battery health, individual cell voltages, state of charge (SoC), and warning alarms.
