Only 4/5 inverters show up

[Pasimk]

Installation found only 4 of my 5 hms-1800 inverters - which are showing as 1600-T models.

Thanks, @LuucA80 has experienced a similar issue.

It seems that the DTU does not report back all inverters to some reason. Can you maybe run the get-real-data-new command from the https://github.com/suaveolent/hoymiles-wifi library?

Thanks, that is exactly what I thought it would look like: sgs_data describes the connected inverters. And only 4 of them are reported back by the command.

Can you maybe also run the get-real-data and app-information-data to see if the remaining inverter shows up somewhere else?

If not, I fear there is nothing really I can do, except maybe ask hoymiles directly why the 5th inverter is not reported.

@Pasimk I also noticed that the DTU serial 10FD... is not currently listed in my mapping. Which DTU do you have?

Thanks. In that case, I probably could add the 5th inverter, but it will not show any data since get-real-data does not report anything. Might be a limitation of the DTU?

I will leave the issue open for now. Maybe I can find something to force the DTU to report all inverters.
