new Events not viewable

[ghost]

I have two HM-1500 (West, Ost) connected to the OpenDTU. I can see the red numbers for both of the inverters in case of new events.
If the numbers exceed a certain number of events they are not listed when trying to open them, it's just an empty list. If there are only small number of events it works without any problem. I do not exactly know what is the breaking number. I must be someting greater than 3 or so. My impression is also it works more stable for the first inverter, I have seen on West more that 10 events listed without any problems. On the 2nd inverter Ost the list is always empty when there more than 3-4 events.

Could you please open the URL: http://<OpenDTU IP>/api/eventlog/status in a browser and post the output? I assume that maybe the buffer for the json output is to small and therefor the entries get cut off.

If you have already compiled it yourself and if you want to test it you can try to replace the line:

OpenDTU/src/WebApi_eventlog.cpp

Line 25 in 85d08e0

AsyncJsonResponse* response = new AsyncJsonResponse();

by the following:
AsyncJsonResponse* response = new AsyncJsonResponse(false, 2048);

This is only a workaround as for more (up to 10 supported inverters) inverters the 2048 will be also to small. I think I have to rework the API a bit.

Ok, I will test that and update here, thanks for the great support and your work!

Looks good now....I will post again here if there are any issues.

@locke981 Danke für die Meldung, ja es gibt noch ein paar Unbekannte / unknown Fehlermeldungen.
U.a.

• 12 (Event Log: ID 12, Unknown #1068),
• 14 (new Events not viewable #131),
• 12, 13, 14, 36, (Event ID 36 #121),
• 12, 14, 36, 46, 47, 73 Unknown alarm codes #590

Ich bin in den assets/warn_code.json der Hoymiles S-Miles Installer App fündig geworden. 🥳

Hier mal die bisher aufgetretenen Fehler oder Warnings aus dem in #121 angehängten warn_code.json (GitHub versteht nur ZIP ?).

11: Grid voltage surge
12: Grid voltage sharp drop
13: Grid frequency mutation
14: Grid phase mutation
36: INV overvoltage or overcurrent
46: FB overvoltage
47: FB overcurrent
71: VW function enable
72: FW function enable
73: TW function enable

Es wird von @tbnobody im Rahmen von #121 in OpenDTU implementiert und daher kann dieses Issue als Duplicate geschlossen werden.
