Looks like everything is on order again:

Tnx for the hard work everyone.
Only the inverter output current stays at zero for the moment. Is this maybe a mismatch in a datapoint?

That is quite strange as for me all devices are being updated:

input - boven and input onder are the 2 strings attached to the inverter
Details for output current:

Bw: there is still a whole bunch of legacy code in the plugin, I'll work a bit on cleaning that up the coming days. You will see in the logfiles now that it default to the old endpoint and then as fallback uses the new one, which is a bit stupid

Watch this :
- My physical Goodwe Inverter says
15,94 Mwh produced (E-Total)
- My Goodwe website says
15.847,30 Kwh produced
Difference about 100 kwh
After the previous update of the plugin i had a negative value in Domoticz, this means that de Total in Domoticz previously was calculated from another variable.
To me it seems that the plugin previously calculated the right value but now uses another variable?
I deleted wrong values but now " Meter_Calender" reads in Domoticz.db :
Code: Select all
2107 10700 15814600 2026-09-20 0
2107 16500 15831100 2026-09-21 0
2107 9600 15840700 2026-09-22 0
2107 0 15840700 2026-09-23 0
2107 0 15840700 2026-09-24 0
2107 10600 15835300 2026-09-28 0

It works now again but it has some strange results.
It seems it sometimes sends values with factor 1000 (Wh -KWh) too much.
The totals for the day are correct so not sure what is going on here. The red bar is because of the few days of errors and not counting.

I made a github issue for this as the plugin resets the counter due to receiving partial values from the portal.

Youre right at that, thats the DC output current, I'm having zero data at the AC output current.

There is probably a Goodwe.log file in your Domoticz home folder. Check the values in that log in a time it is producing more than 1A. I see 0A in Domoticz when the panels are producing less then 1 A. In the graph of the device that should be visible.

I can only find the domoticz log in the domoticz homefolder wich is 70Gb.
Panels are producing voltage and current so thats ok.
For some reason it doesn't want to give the AC value though it is correctly reported last seen.

Where in the Goodwe script i can check if correct calls are assigned to the inverter AC output?
SEMS+ does give the current AC output value but not trough the plugin unfortunately.

The logfile in domoticz folder is the one indeed. Just empty it and restart your plugin then you have a fresh folder. With 70gb you will run out of space at some point. BTW you should enable debug logging only when you have issues otherwise turn it off

This is the debug, AC and Voltage seems to give 0.

I need the logfile content to asses the actual problem. Please create an issue on github with the clear description of what's wrong plus logfile content

Fixed AC-logging of Current and voltages.
For 3-phase models also per phase output reading.
