Missing data in API and VRM portal export

HI,

I am using the API in order to collect status information about my systems (7 in total).

Currently, "bs" (Battery State of Charge) is empty for all systems.

was something changed?


In addition, when I try to export data from the vrm portal in KWH units(15 minutes) - I get an empty file, while if I try to get the kw data (1 minute) - I get all the data

Is there a fault on the server-side?


Thanks

Hi @nir_fsight,

I can query the `bs` for some installations just fine. Can you link me your VRM installation?


Regarding the kWh export: which export are you referring to and do you download it from VRM or the API?

Thanks.

First the bs issue, I just checked your instance and it reports bs just fine:

curl 'https://vrmapi.victronenergy.com/v2/installations/35484/stats?end=1596462000&interval=hours&start=1596402000&type=custom&attributeCodes[]=bs' \

  --compressed
{"success":true,"records":{"bs":[[1596402000000,100,100,100],[1596405600000,100,100,100],[1596409200000,100,100,100],[1596412800000,100,100,100],[1596416400000,100,100,100],[1596420000000,100,100,100],[1596423600000,100,100,100],[1596427200000,100,100,100],[1596430800000,100,100,100],[1596434400000,100,100,100],[1596438000000,100,100,100],[1596441600000,100,100,100],[1596445200000,100,100,100],[1596448800000,100,100,100],[1596452400000,100,100,100],[1596456000000,100,100,100],[1596459600000,100,100,100]]},"totals":{"bs":1700}}

Then the kWh download issue. Just downloaded a kWh export of today, which is not empty:


Please note that for those kWh type of data there are certain requirements:

Hi,

I tried to mimic your API request, and I receive an empty response. How is that possible?

HI,

Those two files downloaded this morning at 8:28 local IL time.

https://drive.google.com/drive/folders/1oZkoeN4XlgPL6OBeqtkTTbfawucaW7Qt?usp=sharing


You are correct: the summary file is not empty - it contains one line of data, while the kw info includes more than 500 lines of data. how can it be?


Thanks

nir

How was this issue resolved. I just compared the energy reading we download via VRM frontend, and the one we downloaded via the API. The API reports lower reading compared to the VRM frontend. How do I correct this?
