Any clever trick to find the previous breach time?

[JanJoh 1]

Lets say i have a script that when fired needs to know when the triggering sensor was last breached previous to the triggering event.

Do i need to create a global var which is compared to current time on breach and then updated.. or is there a shortcut?`

Basically i want a "Ok, someone has entered this room. How long has the room been empty?"

Hm, I suppose I shpuld just create a second script that fires when the sensor has been "safe" for the desired amount of time, and update a global var (room_empty) at that point ?

I'm using this code to switch off some lights when the motion detector has not been breached for a specified time:

Please login or register to see this code.

86 is the ID of the motion detector you want to test for when it was last breached.

Apparantly, this only works with certain versions of the firmware, as some get the "lastBreached" returned as 0 always, but it might be worth a shot to avoid having to use a global.

That logic will not work for me, as i do not want to keep a script running. (bad coding form if you ask me)

I want to be able to trigger a scene and ask the system "So, how long has this room been empty before this triggering event?" And chose a nummer of different scenarios depending inch the length of that time span and a number of different other factors.

Be that as it may, you won't reach your goal with "good" coding practice.

I agree that it is bad coding practice to keep a script running, but with the possibilities you have with the fibaro unit, I don't think there is much else you can do if you don't want to use globals. If you are okay with globals, check the thread called "somebody home" - it does almost the same.

Oh, I never said that i did not WANT to use globals. I was however curious to if there was a more clever way of doing it.
