Problems with previousState

[bbubble62]

I would like to know the time difference between the current time and the time of the previousState of an item, if delta > 10 seconds do something.
Problem is that I cannot get the absolute time of the previous item, I’am able to read the state (working fine) by using

logInfo("sonoff195", sonoff195_Switch.previousState.state.toString)

but I need something like

if (now() - sonoff195_Switch.previousState.time) > 10 then .....

Any hints greatly appreciated!

You must create a DateTime (i.e. new DateTime(now.millis - doorOpen.millis)) but that doesn’t really make sense because that will likely give you a DateTime sometime around 00:05 1970 January 1, not “five minutes” which is what you re…
