Read out of GridProfile failed / how to request it again.

[Elektron79]

What happened?

After restarting the openDTU at night (when the inverters are offline) I was able to reproduce the issue.
At the morning after the Inverter started the wrong (default?) GridCode is shown.

the content of the GridCode is only 02 00 00 01 5c c0 and it is mapped to „US - NA_IEEE1547_240V“. I don’t know if the is correct or if it should simply be „not set“ or „not able to read“?

To Reproduce Bug

Restart the openDTU at night and wait for the inverter to start, most likely when the power is low the inverter is replaying with „garbage“?

Expected Behavior

The openDTU recognizes that the received Data is not valid and requests the data after some time again.

Install Method

Pre-Compiled binary from GitHub

What git-hash/version of OpenDTU?

24.3.22

Relevant log/trace output

No response

Anything else?

Hi @tbnobody ,

I’m not sure if this fix is a good idea. Before I configured the correct Grid code (for Germany) there was „no grid code“ set (at least it was shown as if there was no grid code set in the Hoymiles Cloud connected via a Dtu Pro).

the value received via OpenDTU was the same.

just want to avoid that the OpenDTU ends up in an endless loop for all people which didn’t have a dtu (pro) to set the grid code…

I have no better idea but wanted to highlight this, to start a discussion…

Best regards Michael
