GoodWe

Library for connecting to GoodWe inverter over local network and retrieving runtime sensor values and configuration parameters.

It has been reported to work on GoodWe ET, EH, BT, BH, ES, EM, DT, D-NS, XS and BP families of inverters. It may work on other inverters as well, as long as they listen on UDP port 8899 and respond to one of supported communication protocols.

(If you can't communicate with the inverter despite your model is listed above, it is possible you have old ARM firmware version. Usually the ARM firmware (not inverter firmware) has to be >=13. You should ask manufacturer support to upgrade your ARM firmware to be able to communicate with inveter via UDP.)

Usage

1. Install this package pip install goodwe
2. Write down your GoodWe inverter's IP address (or invoke goodwe.search_inverters())
3. Connect to inverter and read all runtime data, example below

import asyncio
import goodwe


async def get_runtime_data():
    ip_address = '192.168.1.14'

    inverter = await goodwe.connect(ip_address)
    runtime_data = await inverter.read_runtime_data()

    for sensor in inverter.sensors():
        if sensor.id_ in runtime_data:
            print(f"{sensor.id_}: \t\t {sensor.name} = {runtime_data[sensor.id_]} {sensor.unit}")


asyncio.run(get_runtime_data())

or the old way (for XS inverters only), create a processor and inverter instance:

import asyncio
from goodwe import GoodWeInverter, GoodWeXSProcessor

async def get_data():
    ip_address = '192.168.200.100'
    processor = GoodWeXSProcessor()
    inverter = GoodWeInverter(inverter_address=(ip_address, 8899), processor=processor)
    data = await inverter.request_data()
    print(f'power is {data.power} at {data.date:%H:%M:%S}')

asyncio.run(get_data())
