Huawei Solar integration sudenly multiple disconnections

Third party integrations
1

Hi. I have this integration for almost one year, no problem setting it to retrieve data at one second.
Suddenly, I have a lot of disconnections:

This is the part of log:

I must remind that almost ONE year worked very well. I did not updated to 1.5.4, because this was the same behavior when I’ve updated, so I had to downgrade to 1.5.3, which worked very well.
What’s wrong?

HAOS 15.2
Core: 2025.5.3
Huawei Solar version: 1.5.3
Huawei inverter: SUN2000L 6ktl l1
with latest firmware - updated when it was released and worked very well till today.

As a workaround, I’ve made an automation which reload the Huawei integration, if one of its entity gets unavailable for 2 seconds, but I don’t want it like this… I want to make it work again like till today.

Hello Vali Matieș,

If you have a problem with a specific custom integration, your first step should be to check the original GitHub post where you found it. The people there know the product and use the software, so they can give you better help with your issue. You might find someone here who can help, but it’s not guaranteed.

4

There is no issue created on the integration’s github.

More than that, it passes about 20 hours and the automation created as workaround to reload the integration has not been triggered anymore. So, seems that was something with inverter’s wifi connection, I think… I don’t know…

5

Then create one, maybe?
