Averaging values

[tripode]

Hello, I have an analog value from a level sensor, wich has some oscillations I want to filter, in order not to have too many events/alarms when it reaches high or low values. I am trying it by checking the “average” box, but I dont get the expected results. How caould it be done? Thanks in advance.

Hi,
If you tick the Averaging checkbox, it affects on minute and hourly data stored in the archive. But not affects current values. You need custom formulas or develop module that perform averaging.
What averaging algorithm do you need?

OK, understood, so averaging only has something to do with stored archives.

I would like a time averaging value algorithm, just to filter the peaks I have in my analog input.

What period of time and how many points should be included in average value?

Mikhail, 5 minutes and 100 values would be nice.

It is possible to solve the task by creating formulas in the configuration database. Formulas are based on C#. Do you know C#?

I know C/C++, now I will try to learn C# and post here a new function for averaging 🙂

Good 🙂
