ESPHome redodo_bms component

An ESPHome external component to read data from Redodo Battery Management Systems (BMS) via Bluetooth Low Energy (BLE)

Inspired by the following repos:

• https://github.com/mirosieber/Litime_BMS_ESP32
• https://github.com/calledit/LiTime_BMS_bluetooth

I tested this with a Redodo 24V 100Ah battery, but it may also work with Litime and PowerQueen batteries as the projects states above.

Warning

Do not use this integration for safety-critical applications. The data provided by this component is not based on an official protocol description and has not been validated by the manufacturer.
