How to trigger on percentage change in value


Question

I am trying to start the exhaust fan in a bathroom (4 of them) when the humidity changes by a percentage.  I have a simple scene that is using a greater than a fixed value trigger.  This works for now.  However this value will be different in summer / winter and requires permanent tweaking.  What I really want is to turn it on when it increases by more than 1% in say 5 mins.  Similarly I want to stop it when the humidity has not decreased by more than 1% in 30 mins.

 

I can use Lua, but is there any other way that others have done this, or is there a better algorithm ?

Yeah... known issue and complexity.

What kind of humidity sensor you're using... is it Aeon Lab?

Actually the question is do you have motion or light sensor ?
