Logg off from wifi after successfull initialization

[Miroslavgapa]

Describe the issue

Hi, i mean i found a bug with which i am dealing already 2 days. When i succesfully login to inverter AP everything seems fine but after app 3 minutes - wifi is log off. After that integration is showing initializing but is not able to connect through pymodbus to inverter.

I try latest beta 7 version.

Bescribe your Huawei Solar Setup

Inverter Type: Huawei SUN200L 8KTL M1
Inverter Firmware version:V100R001C00SPC146
SDongle present: yes but connection through him is not working, firmware V100R001C00SPC125
Power meter present: no
Battery: None
Battery Firmware version: none

How do you connect to the inverter?

Via the SUN2000-<serial_no> WiFi

Upload your Diagnostics File

I dont have there diagnostic package because initializing status of integration

Upload your relevant debug logs

Please confirm the following:

• The problem is still present in the latest release of this integration.
• I did not find an existing issue describing this problem.
• I did upload the diagnostics-file that I could retrieve from the 'Devices & Services Page'
• I increased the logging configuration, restarted HA, and have copied all relevant log lines from the 'Full Logs' into the textarea.

This is with a probability of 99% a network problem. The integration will periodically retry to restore the connection, little more it can do.

hm i updated sdongle to version V100R001C00SPC133, nmap showing to me that the port is open on port 502 but connection unsucesfully. I am totaly lost and siting behind PC whole day.

[alexualbu]

i did some testing with the huawei-solar package directly in python.
turns out i had to use slave_id 1, but if you start the HA add integration flow and add the wrong values I believe the client does not close properly (it continues to output debug logs). I could only get it to work after restarting home assistant (after validating it works directly in Python with the huawei-solar package). might be a similar situation in your case after the connection drops.

[wlcrs]

@alexualbu interesting observation. I've been suspecting a problem with the underlying pyModbus library in that regard. Hopefully it is fixed in their new version (3.x.x): I've already implemented the upgrade to this version in the beta-releases, but it needs more testing to be deemed stable enough...

[alexualbu]

@wlcrs - it might be something that can be fixed in the config flow of the custom_component here. I didn't have time to dig into it, but given that a connection is established but it throws an exception due to the disconnect, the variable might not be None (I didn't see the successfully connected message after the assignment, so it's probably not the case)
LE: obviously this is the case for the integration setup phase anyway :)

[Rhysgh]

Don’t you need port 6607 for modern fm

[alexualbu]

I have 502 on the same dongle version 🤷
