Can you confirm your output for: /usr/local/bin/sfk 192.168.0.175 8899 -listen -noerror -timeout=1000 0x7f0375940049d5c2 -pure +xed "/[eol]//"

The error you are getting is either misconfig or an offline device.

I am afraid there was another typo, it's sfk cudp

It looks like your inverter is not active on that IP or UDP packets are filtered somehow.

Can you let me know what this responds?
sfk cudp -broad 255.255.255.255 48899 -listen -noerror -timeout=1000 0x574946494b49542d3231343032382d52454144 -flat

Is your Inverter's LED burning solid or flashing orange? It seems like there is some connectivity issue with UDP packets from and to the inverter. Perhaps any switch, in your LAN, that does UDP filtering or outgoing traffic to the internet blocked?

[MilanBacaCz]

wifi led is orange solid. I have Linksys Mx5300 router. I can not see there any blocking udp settings.

[dblommesteijn]

wifi led is orange solid. I have Linksys Mx5600 router. I can not see there any blocking udp settings.

Are you blocking anything going out from your router to the internet for the inverter? SEMS portal receiving info from the Inverter?

[MilanBacaCz]

SEMS is working OK.

[dblommesteijn]

It's a pity this does not work for you out of the box. Unfortunately this UDP method is undocumented by GoodWE, and I think they do not really like the fact someone could potentially circumvent their SEMSportal.

You could try to increase timeout to 10000ms, let the inverter go off by itself later tonight, and check again tomorrow. Or force this by going into the inverter's web-interface via: http://192.168.0.175 (admin:admin) and reload the network module (this sometimes works), but usually a system off/ on is better (you could also force reload on the inverter itself, by clicking the button).

The fact SEMS is working can actually mean two things: or it's connected to SEMS and the UDP setting is not activated (went to sleepmode) somehow. Or there is some other issue why the UDP packages are not being received by your homebridge.

PS. while you're in there, it's best to change the default password of the build-in WiFi.

[MilanBacaCz]

I can't receive these udp packages also on other computer.

[MilanBacaCz]

I tried install python library "goodwe" pip install good we

And below script show me many information from inverter.

Maybe it could help you with my problem :-)

import asyncio
import goodwe

async def get_runtime_data():
ip_address = '192.168.0.175'

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())
