History prior to 2025-03-25 missing in downloaded Variable data

I just downloaded my cloud variable data, but it only included data going back to March 25th, 15:41 GMT. Has the data prior to this been lost?

Thanks.

Hi @ttl7400. It seems somewhat similar to your other report:

Problem with iOS Graph Widget Not Displaying Beginning of Cloud Data History

(New to the Arduino world - hope this post is appropriate here.) There seems to be an issue with the iOS IoT Remote app when it comes to displaying the history of cloud variables in the Graph Widget of a Dashboard. This issue is in the recently released 3.7.4 (226) rev and the prior release. Here are screenshots to illustrate the issue: [PC Dashboard] [IOS_Dashboard] In the first image, the desktop Graph Widgets correctly display the full history of the linked cloud variables. In the se…

It looks like the data also starts at 2025-03-25 in the iOS IoT Remote app screenshots you shared there.

Is the history you downloaded for the same Variables as the ones in those screenshots?

The short answer is yes. The history that I downloaded is for the same Variables in the screenshots.

I have repeated the data download and what I see is that only the last 24 hours of data is included in the .csv files. (The oldest data, from the post I made a couple of hours ago, is now gone.)

In looking at the iOS IoT Remote Graph Widgets, the 7 Day and 15 Day graphs only show data from the prior 12 hours or so. In all cases (on the PC based Dashboard and the iOS Dashboard) the most recent hour’s data is missing from the 7 Day and 15 Day graphs.

Also, I should note, the PC Dashboard still shows all data in the 15 Day and 7 Day graphs. (More or less – as I mentioned, recent data is missing from these graphs.)

Some background context, I’m using the UNO R4 WiFi board to monitor four sensors keeping tabs on fermenting beer. This is the first “production” test.

All the Cloud Variables used in the Sketch were deleted and then recreated with the same names and parameters using the Thing Editor. The Sketch was recompiled and loaded onto the UNO board just as the run started to ensure that the Cloud Variables did not contain old test data.

The graphed variables are all INT types that update only upon changes.
They are also R/W. They are used as Read-Only variables, but setting them as R/W seemed the only way to preserve their values between board re-boots and not have anomalous zeros show up in the Cloud Variable data.
