Bluetti inverter cloud API and BLE protocol, bridged to Home Assistant

What was done

Claude Code read the decompiled Android app and built a cloud-to-MQTT gateway in an evening, then a full Bluetooth control implementation on a Rust ESP32.

Where the human stepped in

Claude struggled with the authentication crypto until told to read the decompiled Java more closely, and it mixed up the Modbus and proprietary pathways for different battery types.
