An ESPHome external component that monitors and controls Jikong (JK) Battery Management Systems over UART-TTL or Bluetooth LE. It exposes BMS telemetry such as cell voltages, temperature, and state of charge to ESPHome and Home Assistant.
Use cases
- monitor JK-BMS battery cells from Home Assistant
- read BMS telemetry over BLE with ESP32
- control JK battery management system settings remotely
- log lithium battery cell voltages and temperatures
- integrate DIY solar battery BMS into home automation
- monitor JK-BMS via UART-TTL serial connection
When to choose
- you run ESPHome/Home Assistant and own a JK-BMS with software version 6.0 or newer
- you want local, wireless-free (UART) or BLE monitoring without vendor cloud apps
- you need cell-level telemetry and BMS control in your automation setup
When to avoid
- your BMS is not a Jikong/JK model or runs software older than 6.0
- you don't use ESPHome and prefer a standalone MQTT bridge or vendor app
- you need a different balancer brand like Heltec or Neey (separate components exist)
