Devices\Growatt To MQTT

Hardware

1. USB-B or USB-A cable
2. for models with a DB9 port a DB9 RS232 adapter is required. "Before use RS232 communication, you should make sure the follow PIN1 and PIN2 are OFF"
3. Connect cable to wifi dongle port; if a alternative usb port exists, try connecting to that one first.

Configuration

Follow configuration example for ModBus RTU to MQTT https://github.com/HotNoob/PythonProtocolGateway/wiki/Configuration-Examples#modbus-rtu-to-mqtt

protocol_version = v0.14

HomeAssistant Cards

Here are some example cards. If you want to use them, you will have to change the variable names and others to reflect your configs.
