Full protocol coverage: binary sensors, energy, hardware version
Sensors added:
- energy_stored (kWh = V × Ah / 1000) for energy dashboard
Binary sensors added (all from existing 0x03 frame, no extra BLE requests):
- Charge MOSFET / Discharge MOSFET (MOS gate status)
- Cell Balancing (any balance bit active)
- 13× protection flags: cell/pack over/under-voltage, charge/discharge
over/under-temperature, charge/discharge over-current, short circuit,
frontend IC error, software lock
Other:
- Hardware version string fetched once via CMD 0x05, shown in device card
- DeviceInfo centralised on coordinator (sensor + binary_sensor share it)
- CONF_ADDRESS removed from sensor.py (coordinator holds address)

Initial commit: Xiaoxiang Smart BMS Home Assistant integration
- BLE GATT communication via bleak (UART-over-GATT, service 0xff00)
- Parses 0x03 (general info) and 0x04 (cell voltages) frames
- Protocol verified against official RS485/UART spec V4
- DataUpdateCoordinator with 5s poll interval (configurable 2-60s)
- Auto-reconnect on BLE disconnect
- Config flow: BT auto-discovery + manual MAC entry + options flow
- Sensors: voltage, current, power, SoC, capacity, cycles, temps, cells, cell delta
- HACS-ready (hacs.json, manifest.json)
