@gmrza: I had to look at your data in the database and noticed an anomaly. The entries do not appear to be in order, which I suspect may be an artifact of how it was created or imported.Since you have a reasonably small dataset, could you attach the file you are using for importing the data? I would like to check if the issue is in the data itself or is a bug in our import process.
The data I uploaded is here:
http://www.rehmet.alt.za/wp-content/uploads/flowlog.csv
The steps I followed we essentially to clear the feed, start uploading of new data (the daemon which logs flow data calls a script which then uploads the reading via the API), and then populate the old data by uploading the CSV. This meant that I had a couple of data points uploaded via the API before I uploaded the CSV.
There is one other issue I am running into in that when I do a daily sum, the sum for each day runs from 11:00 AEDT to 19:59 AEDT the next day - i.e. from 0:00 UTC to 23:59 UTC, where I actually want to sum from 0:00 to 23:59:59 Melbourne time.
This is happening even when I specify the timezone in the URL:
(Sydney and Melbourne are in the same timezone.)
Aside from the timezone issue, the result is looking quite good.
(It has been raining, so I have not had to water the garden in the last couple of days.
