How to download data? in web dashboard and app

Hi

I’m having problems with data exportation. I have a template with about 70 Virtual pin datastreams, feeding 18 charts and 8 labels. All looks good by looking at the charts on the web dashboard, all data appears as I expected. In the web dashboard, when I try to ‘Download report’, I get a zipped file with 3 files within, a csv for the data, anotehr for the connections made (Online…offline timeline) and a metadata file. My interest is only in the data file which comes out blank, always. How is that possible when I can clearly see data in the charts?
I saw a few posts about downloading a csv file from the superchart in the dashboard , I went to Blynk IOT app and made a superchart with 2 of the datastreams I use and see in the web dashboard, I can see the data being plotted in this chart but I can’t see a way to extract the csv data, is it only in the previous app?
I’m probably missing somethng big here =\

Can anyone tell me possible reasons for the web dashoard report data come empty?
And how to doenload t from the app as well? Although I rather just stick with the web dashboard.

Thank you.

Cheers, Luís Pereira.

report widget

I can’t find that widget on the app or the web dashboard.

I just saw a ‘Save Raw data’ switch button on each datastream ‘Advance settings’ and it was turned off…
The info about this switch says data is stored as 1 average per minute by defaut, so my raw report data would always come blank. But the 1 minute average comes out ok. The csv with the data comes with all datastreams on the same collumns …could have separated these in different collumns no? 1 per datastreams would seem more logic and easy no analyse.
Still haven’t figured out how to download data from the app though.

What type of Blynk subscription do you have?

I purchased Blynk Plus.

That’s how the report is structured. You can filter or pivot the data if you want it in a different format.

I don’t think it’s possible (yet).

Pete.

Thank you.
The collumn thing is easy to solve with a quick R script. The app download option doesn’t bother me, I rather the web dashboard anyway.

What file comes blank?

Did you try to select “avg” aggregation instead of “raw”?

Hi Dmitriy

Yes, that solved it, I hadn’t notice the default of 1 min avg, hence the raw data csv always came blank.
Thank you.

Cheers, Luís Pereira.
