How see by second data for a historical date

[rowan.bradley]

I need to see the by second data for last April, since that’s the last ime my solar PV array and the Emporia Vue were both working correctly. How do I do this? It seems that both on the app and on the website I can only see data finishing with the current date. So if I select by second data, I can only see the data for the last few minutes. I would have expected to be able to scroll back in time, or to display the month of April last year, and double click it (maybe several times to get to seconds) to expand the view. Can I do any of thee things? How?

Thank you – Rowan

Second data is only saved for a short amount of time.  I forget the specifics, but thought it was saved for a few hours (3 maybe?).

They used to save this to the cloud, but they made a change a couple years ago to not do so.  Believe due to storage reasons.

Sorry, but any seconds data from a year ago would not be saved.  What are you looking to see from your solar data that minutes would not cover?

I need to calculate whether adding a batery to my solar system will save me money, and if so how much. To do this I need to know how much “spare” energy is generated by the solar PV that we are not using (that could be used to charge the battery) and how much we draw from the grid (which could potentially be supplied by the battery). If the Vue could give me Watt-hours, then I would not need second by second data, but as far as I know it does not, so I think I need the second by second data to calculate the surplus watt-hours.

How best do I do this?

If it is true that Emporia only stores the second by second data for a few hours, then I can potentially download the data every hour and thus build up the history that I need, but if possible I would like to use historical data, rather than have to wait for a wole year to build up new data.
