+## Untested devices
+
+* JK-BD6A20S6P
+
+## Requirements
+
+* [ESPHome 2022.11.0 or higher](https://github.com/esphome/esphome/releases).
+* Generic ESP32 or ESP8266 board
+
+## Schematics
+
+

+
+
+The UART-TTL (labeled as `RS485`) socket of the BMS can be attached to any UART pins of the ESP. A hardware UART should be preferred because of the high baudrate (115200 baud). The connector is called 4 Pin JST with 1.25mm pitch.

+## 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-jk-bms@main
+```
+
+or just use the `esp32-example.yaml` as proof of concept:
+
+```bash
+# Install esphome
+pip3 install esphome
+
+# Clone this external component
+git clone https://github.com/syssi/esphome-jk-bms.git
+cd esphome-jk-bms
+
+# Create a secrets.yaml containing some setup specific secrets
+cat > secrets.yaml <= 6.0 and < 11.0)
+ # Please use "JK02_32S" if you own a new JK-BMS >= hardware version 11.0 (f.e. JK-B2A8S20P hw 11.XW, sw 11.26)
+ # Please use "JK04" if you have some old JK-BMS <= hardware version 3.0 (f.e. JK-B2A16S hw 3.0, sw. 3.3.0)
