Is your tank running too low ? Are your programs draining too much from it?

Hi all,
here you will (hopefully !) find a solution to address the question in the topic title.

Last year I did not pose the question to myself, since I did not have the evapotranspiration corrections available.

In these days, where my local Zimmermann corrections are in the 150 % range, I was forced to answer to the question !
In fact, some days ago in the morning, I noticed that, after one hour or so from the last irrigation session, the flowmeter of the water supply was still running.

I made an R script (sorry. It’s the only program language I know) to calculate the possible water deficit.
Since I think that R (https://cran.r-project.org/) is not much known in this community, the script is commented, to help you in the customization process.

It’s a matter of fluxes: the very large one for some stations (38 lt/min) and the very small flux from the water supply (3lt/min).
The two fluxes are the combined with the frequency of the irrigation sessions.

I hope you’ll find it useful.

Thanks for sharing the script. If I understand it correctly, this script analyzes the log data to check if the water consumption is within the acceptable range, is that right?

Yes. It analyze only the past.

I realize that is not easy to modify the backup.json file.

If needed, I can modify the script to:
export the data into a more readable and editable form as csv.
modify the data (by the user)
reimport the modified data and get the results for simulated programs
