ESPHome JBD (Redodo / PowerQueen) BMS Monitor (BLE)

This project provides a robust ESPHome integration for monitoring Redodo LiFePO4 batteries and other JBD-based BMS (Jiabaida) via Bluetooth Low Energy. It is compatible with both 12V and 24V configurations.

Supported Hardware

• Batteries: Redodo & PowerQueen 12V/24V LiFePO4 with Bluetooth, or any battery using JBD BMS.
• Controller: ESP32 (DevKit V1, WROOM, etc.) - Bluetooth is required.

Features

• 📊 Dynamic Cell Monitoring: Automatically reports voltage for each cell (4S for 12V, 8S for 24V).
• 🔋 Full Battery Stats: Total Voltage, Current, SOC (%), and Cycle count.
• 🌡️ Health & Safety: Temperature monitoring and BMS status.
• 🛠️ Diagnostics: Integrated Web Interface for standalone monitoring without Home Assistant.

How to use

1. Copy secrets.yaml.example to secrets.yaml.
2. Fill in your WiFi credentials and the MAC address of your BMS.
3. Flash the ESP32:

   esphome run esp_redodo_bms.yaml
   

🏠 Integration

• Home Assistant: Automated discovery via the native ESPHome API.
• Other Systems: Supports MQTT, Prometheus, and REST API for integration with Node-RED, OpenHAB, or custom dashboards.
• Standalone: Real-time dashboard available via the ESP32's web interface (IP address).
