Summary0000173: Multiple inverters and single smartmeter leads to energy consumption duplication on
DescriptionCurrent setup:
2 SMA inverters configured enabling pvoutput (each inverter has it's own SID on
1 SmartMeter (php)
weather device receives updates for each inverter combined with the smartmeter data. This means that the smart meter data gets duplicated on
Steps To Reproducesetup 2 inverters, each with pvout configured and it's own sid.
setup 1 smartmeter

Marco, please allow me to disagree with the severity, I find it very annoying to have my data to be completely unreliable because websolarlog updates wrong data. Please upgrade the severity to major!

I see two possible solutions:

1. allow smart meters to have their independant upload to (their own sid)


2. add a field to each production device where the user selects whether or not the data from the smart meters should be uploaded, with a clear message stating that selecting this on multiple sids might lead to data duplication.

Gijs, you reported it with this severity!
If I or we have time, we will take a look at it.....

At the moment we have more thing to do.
You could always disable the PVoutput and submit it manually.

I tried the 1690 change set - but now the 1st inverter reports 25,770 kWh for the day and the second reports 12.873 kWh. It seems the total figure is off. Not sure how I can get the data from the database to compare...

You could go to the today.php and navigate to that day.
then check the end of the "cum. YourInverter" lines and see what the inverter produced.

Your WSL shows for 26-2-2014:
Behoudten_Huys_1: 7328W
Behoudten_Huys_2: 6852W

PVoutput shows for 26-2-2014:
Behoudten_Huys_1: 7328W
Behoudten_Huys_2: 6852W

For me this looks great, or do i mis something or did you manually changed these figures?

I think you are looking at the wrong data...

It's the power consumption (not the generation) data that is being duplicated.

check these figures for 28-02-14

device energy used
pvout sid 18854 74.742,00 kWh (combination of Behoudten_Huys_1 and Behoudten_Huys_2)
pvout sid 18838 Behoudten_Huys_2 37.371,00 kWh
pvout sid 18839 Behoudten_Huys_1 37.371,00 kWh

wsl_low 11.796,00 kWh
wsl_high 25.518,00 kWh
wsl_total 37.314,00 kWh

so pvout reports 74742 kWh used for the day and wsl reports only 37.314 (which is roughly half).

OK, What i see;
You have 2 PVoutput devices in PVoutput combined to 1 system.
I see that two devices are submitting usage data to PVoutput.
So my question is;
Did you uncheck the box "Send SmartMeter with device" in Admin::Devices::YourDevice for atleast 1 device?

The last 2 days i made some changes. I Also tried severals ways to contact you but without result.

For what i can see on PVoutput, it looks like its solved.

Could tell me if this problem is solved?

OK - stupid user: I overlooked the checkbox :-). I corrected it yesterday and I can confirm that as of today I have a pvoutput that matches my websolarlog.

The issue can be resolved!
