Under "Serial" what are you men RS232 ? Because Growatt use Modbus RS485
Under "Serial" what are you men RS232 ? Because Growatt use Modbus RS485
I'm using RS485, I mean Serial during the configuration as Communication Layer, then I defined the serial port parameters, but I checked the log and found this warning:
WARNING (MainThread) [custom_components.growatt_local.API.growatt] Inverter Modbus version not default supported.
The full logs should actually give you more info about the device data received.
You could also make an example.py with the following code which should be located in in the growatt_local/API folder. In order to run it make sure you have the dependencies installed
import asyncio
from growatt import GrowattSerial, get_device_info
growatt = GrowattSerial("/dev/ttyUSB0") # optional other serial port configrations
1 # Inverter modbus adress
async def main():
await growatt.connect()
modbus_address = 1 # default address should be 1 but depends on inverter
result = await get_device_info(growatt, modbus_address)
print(result)
asyncio.run(main())
If the result from the above example is nothing check modbus_address or the physical connection

Hi @WouterTuinstra,
I created and executed the python file, and got the following error:
WARNING growatt:368 Inverter Modbus version not default supported. Check full logs to get device information using the supported protocols. None
Off course annoying Python default logging starts at warning while on info level it would actually show you the device info it gets. Do you get to the device info screen? because if configure your protocol it should make a entry.
Only other reason I can think of does Home Assistant have rights to access to the device /dev/ttyUSB0?
import asyncio
from growatt import GrowattSerial, get_device_info
import logging
logging.basicConfig(level=logging.INFO)
growatt = GrowattSerial("/dev/ttyUSB0") # optional other serial port configrations
1 # Inverter modbus adress
async def main():
await growatt.connect()
modbus_address = 1 # default address should be 1 but depends on inverter
result = await get_device_info(growatt, modbus_address)
print(result)
asyncio.run(main())
Hi,
I'm creating a new integration to Growatt Model M6000HX-48-BP using Home Assistant and serial port /dev/ttyUSB0. Once I defined the serial port parameters I checked the log and found the following error:
WARNING (MainThread) [custom_components.growatt_local.API.growatt] Inverter Modbus version not default supported.
Any hints?
