the outlier removal is based on the following method http://de.wikihow.com/Ausrei%C3%9Fer-nach-Grubbs-berechnen

Really interesting. I will test it. Eventually we can make this a bit more global in pimatic.

I like the idea and @Icesory is right, this would be very useful in other plugins / devices as well.

@torso70 Thank you very much for the implementation. We should get rid of the massive code dublication. Can you refactor the filtering to a single function? Maybe this could be implemented as an device config extension (like xLink, xOnLabel, ...).

I try to refactor it to a function but the coffeescript syntax drives me crazy... I usually develop in Java ;-)

@torso70 Any news on this one? We now have pimatic-filter which might be an alternative. Moreover, it is possible to provide an expression as part of the device configuration for post-processing temperature and humidity values.
