Was wondering - is there a way to trigger based on the rate of change of a value - perhaps temperature or light ?
The particular application was sensing the drop in hot water temperature in the cylinder - ie knowing that hot water was being drawn. I can't set a temperature threshold as the tank loses heat naturally - so I wanted to know if it was losing above that rate (and potentially just how much).
