Check that S05 timseries is monotonic for each meter

[antonroman]

S05 should give the value of the meter at the end of everyday and it should always be equal or higher than the day before. If there is a negative delta it can be a meaningful input variable to detect anomalies.

Thanks!

I've created a script for this purpose called check_monotonic_s05.py. The output of this script is here, and I can tell you it's not empty, or said with other words, there are some negative deltas.

I will check why there are negative deltas

I have manually checked what happens when the deltas are negative, so I share with you some screenshots of the reactive values of some affected meters the days before and after this issue:

I can make some appreciations here:

• It usually recovers the monotonic value just the day after (or two days after).
• The value for the affected row is not 0, as we thought it would be.
• In the last screenshot, for the R1 column, the 192nd and 193rd rows seem to be the error, rather than the 194th (where the delta is negative), since in the 194th the previous accumulated value is recovered.
