it did first steps in adjusting a sensors warn and error level by analysing historic data. So I read about and started some historic data reports with different adjustments of percentile type, average interval and mode.
First, the outcome of the report was not clear to me. First it switched to calculating a medium value even though I said I want to see raw data. This happens even if I choose a very short time window just containing a few measures.
Second problem is, I could not see which values are used for calculating a medium value. So if my sensor has a interval of 60 seconds and I set the average interval to 180, which measures belong to the medium calculation.
Third, the impact of choosing medium, maximum or minimum mode of the channel to the outcome of the report was not explained.
I found nothing special in the documentation about that, just rough documentation.
Could anyone explain that.
