No data in OpenAPI mode since January 1st

[Brandyellow]

I stopped receiving data on my "Total current day energy" entity 14:00 CET on the 1st of January. Currently when opening the entity I get the following error message: "This entity is no longer being provided by the fusion_solar integration. If the entity is no longer in use, delete it in settings." This is the same for all entities provided by my Fusion Solar OpenAPI integration.

I have my integration configured in core.config_entries:

I am hesitant to remove the integration and set it up again since I don't wanna lose the old statistics.

When trying to add new hub I get the error message "Could not authenticate with the provided credentials.":

Same problem here, all entities are unavailable since 2nd of January, 19:18 gmt+1

Are other entities still updating? Are you willing to share your credentials with me? (‘FusionSolar-ha at verkoyen dot eu’)

I am experiencing the same issue, though in my installation it started randomly on the 4th of January:

Fusion Solar app is working fine on the other hand:

This means the credentials are not valid. Can you check with your installer if they have disabled the credentials?

You can verify your credentials by doing a curl call like below.

curl --location 'https://eu5.fusionsolar.huawei.com/thirdData/login' \
--header 'Content-Type: application/json' \
--data '{
    "userName": "XXX",
    "systemCode": "YYY"
}'

Check if you need to alter the base hostname https://eu5.fusionsolar.huawei.com. And replace XXX with your username and YYY with your password.

The response should look like:

{
  "data": null,
  "success": true,
  "failCode": 0, 
  "params": {},
  "message": null
}

I used Postman to send a login request to Fusionsolar and got the response "northbound system has expired."

For me, no entitites are updating at all. All 128 entities are "no longer provided by the fusion_solar integration".

Should I contact my installer to check if my account is still active? Are you helped by my credentials?

Great work on all of this, @tijsverkoyen!

All entites are in the same state, not available.

Of course I can share my credentials with you, but I do not want to write here, can I send a private message somehow?

Yes. The error means your credentials are not valid anymore.

Feel free to mail the, as mentioned above, to: ‘fusionSolar-ha [at] verkoyen [dot] eu’ Or you can check yourself if they are still valid: How can I verify my Northbound API / OpenAPI credentials?

Yes. The error means your credentials are not valid anymore.

I've added a ticket to my installer (1komma5) and we'll see how they respond.

[ugfus1630]

I have sent my credentials to you.

@ugfus1630 You have the same issue as @Brandyellow. You will need to contact your installer to check your credentials.

oh, I am going to contact with my installer, thank you very much!

[Brandyellow]

I guess this issue can be closed now.

Thank you again, @tijsverkoyen!
