ESPHome component to monitor a DALY Battery Management System via BLE

## Supported devices

* Daly Smart BMS K Series 100A advertised via BLE as `DL-xxxxxxxxxxxx` (e.g. `DL-40D63C3223A2`) or `DL-Fxxxxxxxxxxxx` (e.g. `DL-F28BBED000824`) where the MAC address is the `xxxxxxxxxxxx`

* Probably all models of the Daly Smart BMS H/K/M/S series (start of frame: `0xD2`, Modbus frames)

## Unsupported devices because of a different protocol

* Daly Smart BMS J/T/A/U/W/ND series (start of frame: `0xA5`)

## Requirements

* [ESPHome 2024.6.0 or higher](https://github.com/esphome/esphome/releases)

* Generic ESP32 board

## Installation

You can install this component with [ESPHome external components feature](https://esphome.io/components/external_components.html) like this:

```yaml

external_components:

  - source: github://syssi/esphome-daly-bms@main

```

or just use the `esp32-ble-example.yaml` as proof of concept:

```bash

# Install esphome

pip3 install esphome

# Clone this external component

git clone https://github.com/syssi/esphome-daly-bms.git

cd esphome-daly-bms

# Create a secrets.yaml containing some setup specific secrets

cat > secrets.yaml <
