Multi inverter owners have a bit or a lot more traffic and will struggle if they might recognice a flaw or issue in the tab with the protocol .
Then the current amount of lines shown there is too limited and usually stops somewhere randomly in the middle where you have seen an error but further details (lines) are missing like in my case the MiC that caused a full stop.
If you read the lines and then press actualize the next page of protocoll will be shown, but not the following lines after the issue. You will get the lines of the moment you pressed actualise and that will not help any further cause the time for reading will be too long and new messages will have past meanwhile.
Therefore I suggest to offer an option in the configuration tab to set the amount of lines shown in the protocoll - at least offered for Multi inverter owners which you might detect by the lines {}.
Yes, I guess there is a log file deep down to be found in the file system under /config/grott that might deliver all the data, BUT
I simply want to have the same opportunity as a single inverter user who can read along what is coming from his inverter stick and passed over grott add on and therefore I would need more lines. I do not believe that a choice option between 50 or 100 or 200 lines would be more usefull. I guess each multi inverter owner will choose it differently to his needs in case he faces issues .
I have 8 and there is a lot going on when all inverters / stricks are sending messages every single minute, cause sometimes 3 inverters will send their messages within 2 seconds and then 30 seconds nothing, before the next wave of 2 inverters will report.
I am writing this due to a mistake I had made cause I had copied my multi inverter line with the {} from my notes and not a grott.ini Therefore I pasted a line which still had 2 mic inverters inside
The grott add on worked fine in the beginning til the mic message arrived and then stopped until watchdog caused a restart without a notice so after 5 or 10 minutes i believed everything was fine cause the growatt cloud showed most recent data as I believed.
When I finally recogniced that something was wrong I checked the addon and saw it was grey, i opened the addon and saw the red circle on the top which meant not running. I pressed start / restart and it turned green again so everything looked normal cause my whole roof, I mean 13 strings were updated instantly. And that is an impressive moment at least if you went from not available in the screenshot below to all data displayed like here within a second.
I use these power sensors to calculate the key figure power / kWp to be able to compare strings and see what is going on and investigate what like a shadow or a bad mc4 connector and what not cause a power / kWp underperformance has to have a cause in case of similiar orientaton, pitch and same panels. Same for kWh / kWp which is the long time comparison for example of a day to make sure that planning was right.
And when I pressed restart inside the grott ha add on seconds later I got this
ATTENTION: the upper part on the strings side is showing power per kWp BUT in the lower part there is a summary of the green and yellow inverters which belong to 2 different "accounting" systems with the sum or total in the middle and these 3 figures are in kW for the accounting unit , not a kW / kWp
Back to the point: when I had restarted grott ha addon I went back to the protocol and found something like this but with a mic error which caused a full stop of the integration which then restarted due to watchdog being active. And those watchdog restarts supplied the data to growatt cloud and let me believe it was working now.
Attention: this screenshot is only representing the spot where I had faced the issues it so not the moment or second the MIC inverter had cause the server / grott add on to stop cause I was not able to find that moment where i could see the mic stop happening. I had seen that error only once, read through the lines and when I pressed actualize all these lines were gone and the new lines were from minutes or seconds later.
Hard to explain, but all multi inverter owners can face the same issue and will struggle without a protocoll length that is usefull for them.
