newest version in Code no longer works with my GW3600-EH

[janjos0]

Hi, Just to inform that using release version 0.3.3, I can get/read the data from my GW3600-EH. With the newest versions in Code https://github.com/marcelblijleven/goodwe/tree/master/goodwe I always get error messages Unable to connect to the inverter at ... No valid response received ...

Maybe it is just my limited knowledge how to do it. I use your code in a Windows 10 machine where I made a folder that includes the goodwe folder with the files from the library and a .py file with your example code to read the data:

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())

Thanks for feedback ! The redesign I did due to the new TCP stuff was rather big and I might broke something. It worked form my IDE, but I need to re-test it.

[mletenay]

I indeed forgot to add new port parameter to the initial discovery method ! It should be fixed now. Thanks for testing !

You are the one we must thank, so thank you for this code.

Unfortunately still does not work with my GW3600-EH.

This is what I get when using the newest files from https://github.com/marcelblijleven/goodwe/tree/master/goodwe : Traceback (most recent call last): File "c:\users\public\software\python\code\mygoodwev2\goodwe\inverter.py", line 143, in _read_from_socket result = await command.execute(self._protocol) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "c:\users\public\software\python\code\mygoodwev2\goodwe\protocol.py", line 319, in execute response_future = await protocol.send_request(self) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "c:\users\public\software\python\code\mygoodwev2\goodwe\protocol.py", line 106, in send_request await response_future goodwe.exceptions.MaxRetriesException

During handling of the above exception, another exception occurred:

And this is what I get when using the files from the published version 0.3.3:

I connect to the inverter via its own WiFi on IP 10.10.100.253 and, I think, using UDP protocol.

[mletenay]

Is it 100% reproducible ? Since the UDP (and inverter wifi module) is by definition unreliable and it sometimes happen it does not reply in time even after 3 retries (the retry and timeout are configurable). That exception is raised when it failed after 3 attempts. Please try again couple of times and let me know ...

[janjos0]

Yes, it is reproducible. I tested yesterday several times and also this morning, >10. I don't know what is the time between retries and timeout period, but with the newest files it shows the errors like just two seconds after starting the program from a Windows cmd line. If I use the 0.3.3 version it works fine.

Can you please confirm that the example code in the README -> USAGE and after writing the correct IP, 10.10.100.253 in my case, is still valid to test the new files ? I ask this, because like I said before, my programming knowledge is very limited.

[mletenay]

You are using it the correct way, I just introduced there couple of bugs ;-( It should be fixed now, please re-test/

[janjos0]

Now it works. I do have the feeling that the connection fails more often but it surely works. Thank you.

Something else about the data from my inverter, I don't know if you noticed this (wrong) reading temperature_module: Inverter Temperature (Module) = 3276.7 C It always shows this very high temperature value. Maybe it is because my type of inverter does not have this sensor built-in, so the register just reports erroneous data.

[mletenay]

Yes, it seem EH inverter do not support module temperature sensors and return 0x7FFF. I've just fixed that so it is reported as None.
