oglok commented 12 months ago

Describe the issue

With latest Home Assistant version extension is not connecting to the inverter:

Home Assistant 2023.10.3 Frontend 20231005.0 - latest

Bescribe your Huawei Solar Setup

Inverter Type: Inverter Firmware version: SDongle present: no Power meter present: single phase

How do you connect to the inverter?

Via the SUN2000-<serial_no> WiFi

Upload your Diagnostics File

I cannot get the integration done from scratch. I don't have the integration configured to get logs from any device. However, my home assistant has the 192.168.200.100 address and the inverter .1 is reachable.

Upload your relevant debug logs

Please confirm the following:

[X] The problem is still present in the latest release of this integration.
[X] I did not find an existing issue describing this problem.
[X] I did upload the diagnostics-file that I could retrieve from the 'Devices & Services Page'
[X] I did upload the relevant debug logs (via 'Enable Debug Logging'-feature or by manually configuring HA logging)

Plus. Me too.

Please do not use the issue tracker for connectivity problems.

oglok commented 11 months ago

Sorry, but this issue is not a connectivity problem. There is ping between HA and the inverter.

Hi I'm facing the same issue as you @oglok and it seems more complex than a connectivity issue IMHO. I tried all network/port combinations and had these connectivity issues: Failed to connect [Errno 111] Connect call failed ('192.168.200.1', 502) Failed to connect [Errno 111] Connect call failed ('192.168.2.115', 6607) Failed to connect [Errno 111] Connect call failed ('192.168.2.131', 6607) I posted my issue on https://community.home-assistant.io/t/integration-solar-inverter-huawei-2000l/132350/2805?u=usch72 and was finally able to complete the integration while I was trying to debug what could be causing the issue. I installed tcpdump as explained here. I started tcpdump inside the homeassistant docker listening on dst host 192.168.200.1 and with tcpdump running I was able to complete the integration with an installed PW dialogue coming up that wasn't shown in previous attempts. I have no clue which difference it makes to run tcpdump in the container during installation but hope this info is useful for you as well. Also FYI @wlcrs

Thanks for the great work - Ulrich

How does i fix this issue?

Thanks a lot

Same problem here... Working like a charm for many weeks until today. Home Assistant says (huawei_solar.exceptions.ConnectionInterruptedException: Modbus client is not connected to the inverter.) But the ew11 is working perfectly and publishing data through the the mqtt queue.

Edit: Rebooting the ew11 module fixed the problem :/

lakatusch commented 8 months ago

wait an hour and than do a SYSTEM reboot of HA... this work for me...
