Error when switching to off grid mode

Hi all!

I have the following error when switching to off grid mode. I want to force my goodwe to go off grid to protect the house from power spikes.

I get the same error on the 5048ES.

The service is able to successfully set off-grid mode on the inverter, but because of this error, the integration still think the inverter is in the previous mode (eg. general or eco mode). So if you want to go back to the previous mode, you have to set another mode first. Eg. if you were in general and offgrid mode, you first have to set it to eco, then you can set it back to general to leave offgrid mode.

Is it just problems of reliability of the commands ? (In that case increasing retry-count might help).
Or is it problem that the call to _set_relay_control always fails with your firmware version ?

To the best of my fault finding I belive it is the parameter "set relay control" it always fails. And the HA gives the timeout were it outputs that after 10 tries the parameter has failed.Goodwe has updated my firmware last week to 2525J and the issue is still there 🙂Can you maby disable that relay control for the ES and then I can test for you?On 21 Dec 2023, at 16:56, mletenay ***@***.***> wrote: Is it just problems of reliability of the commands ?

I get the same problem on 5048ES, as @tinuva mentioned change to eco first then normal works.
