Averaging measurements...

#1 Post by grovkillen » 14 Feb 2019, 09:51

A question arise on GitHub in terms of averaging measurements making them less "jumpy". This is how I would do a 10 sample averaging filter:

Code: Select all

On Temp#Value Do
  Let,10,[VAR#9]
  Let,9,[VAR#8]
  Let,8,[VAR#7]
  Let,7,[VAR#6]
  Let,6,[VAR#5]
  Let,5,[VAR#4]
  Let,4,[VAR#3]
  Let,3,[VAR#2]
  Let,2,[VAR#1]
  Let,1,[Temp#Value]
  TaskValueSet,12,1,([VAR#1]+[VAR#2]+[VAR#3]+[VAR#4]+[VAR#5]+[VAR#6]+[VAR#7]+[VAR#8]+[VAR#9]+[VAR#10])/10
EndOn

Also need to filter out off values. e.g ds18b20 often gets either a max (120?) or min (-60?) *C. Might want to filter those out as they will bump your 10 point avrg significantly

I'd say that the 10 point average would swallow those pretty good but yes adding some if to that Let,1,[Temp#Value] could be a good thing. Thanks for suggesting that.
