Hi Tim,

Thanks for the feedback. I’m glad see that it’s still getting some use.

I tried adding Voltage to the printout, but I am doing something wrong:

Voltage_AC_Phase_1 248.9

The above is what I see when I interrogate the inverter for the channel.

I added it to the URL Grab as:
…lute&Channel=PowerReal_PAC_Sum&Channel=Voltage_AC_Phase_1";

Added the extra label:
echo “Time,Energy Generated,Power Generated,Energy Consumed, Voltage\n”;

But I am not sure how to format it in the array section:

$Voltage_AC_Phase_1 = $arr[“Body”][“Data”]["meter:IME - Smart Meter 63A-1 - " . $meterSerial][“Data”][“Voltage_AC_Phase_1”][“Values”][$x];

AS it is not happy when it tries to pull as it does not seem to find a voltage value:

Warning: Undefined array key “Voltage_AC_Phase_1” in D:\Data\Documents\Solar\getFroniusArchiveData.php on line 45

Warning: Trying to access array offset on value of type null in D:\Data\Documents\Solar\getFroniusArchiveData.php on line 45

Hi,

I just tested the CURRENT version of my script against my Symo. I ran it on my iMac using PHP 8.2.12. Both my inverter and Fronius Smart Meter have the latest firmware. I had to make and modifications to the script for quite some time. The same rules apply regarding altering the IP address and required extraction date.

I will re-post the entire script below. The CURRENT script extracts and reports Voltage_AC_Phase_1 AND Temperature_Powerstage by default as I log both of these to PVO.

[EDIT]I was able to extract data from the 1st of May 2023 but not the 1st of April 2023 so it is possible to go back quite a few months.[/EDIT]

Thank you for that. This is my clipped output from my Fronius Primo 5K inverter.
I just used my fixed IP and set teh date and time as usual.:

Exactly what I need. Appreciate the quick response.
The header is not working right, but can work out the columns fine.

#46

Hi. Glad it works. I extract and upload the DC power values of both strings and upload them to my PVO account. You can either amend the script so that it does not output the extra column headers and fields or simply not upload them to PVO.

#47

Yep, I will just disable the additional columns for PVO upload. They make that nice and simple. Thanks again

#48

Thanks for the script grannos, your work on it is greatly appreciated.
I noticed a few issues for my setup stemming from a different smart meter:
“CCS WattNode WND-3D-480-MB”
My simple fix was to change IME > CCS on lines ~64 + 65 from memory. Worked a treat after that.

Log push didnt fill in all days/gaps after wifi glitch

Hi thanks for the feedback. I am glad that the script was of use to you.

Fronius - Automatically fixing lost data
#50

@grannos - Just gave this a go and it worked. Awesome! Much easier than the manual Excel route.

Some feedback:

Could be worth adding an example rather than ‘fronius’ and how you can find this. For me it was via the home network. Probably a simplier way.

$dataManagerIP = “192.168.68.XXX”;

I found it a little confusing to know exactly what to comment out or not on dates and time. Once I got it working I added the two lines below so it is clear on the range.

echo "Date: ", $date, “\n”;
echo "Time: ", $time, “\n”;

#51

One last thing.

I am now trying to upload the output to PVO via the Live Loader. I only need Time, Energy Generation (Wh), Power Generation (W), Energy Consumption (Wh) and Power Used (W).

Is this right?

Date Format = CSV
Output Daye = yyyy-mm-dd
Energy Values = Daily Cumulative or daily interval?
Fields:
Time = 1 HH24:mm
Power Generation = 2 W
Power Consumption = 3 W

echo "Time,v1,v2,v3,MPP1,MPP2,MPPT,InvTemp,v6\n";
// EnergyReal_WAC_Sum_Cumulative . "," . $PowerReal_PAC_Sum . "," . $consumed . "," . $P1 . "," . $P2 . "," . $PTOTAL . "," . $InverterTemperature . "," . $Voltage_AC_Phase_1 
// 1 = Time (HH24:mm)
// 2 = EnergyReal_WAC_Sum_Cumulative
// 3 = PowerReal_PAC_Sum
// 4 = consumed
// 5 = P1 
// 6 = P2 
// 7 = PTOTAL 
// 8 = InverterTemperature
// 9 = Voltage_AC_Phase_1
#52

@grannos Am I right in assuming this script doesn’t work for Gen24 because the GetArchiveData.cgi API doesn’t exist?

#53

You are unfortunately correct. The archive feature doesn’t appear to be available on the GEN24.

#54

How can this script be modified to provide non-cumulative values?

#55

Hi @darrinm81. The script could be modified to return interval ENERGY values rather than cumulative values. The GetArchiveData API returns values at 300 second intervals. When I wrote the script I preferred to use cumulative values as it was easier to detect any gross errors ( sanity check ) before posting the data to PVO.
