Stops reports and engine hours

pic is here

Hi,

I have question
yesterday I added the attribute "Ignition" to a device, where it was reporting "io1" instead
then I noticed that in my stops report, Engine Hours reading start showing up next to the Duration as in the picture, "I thought it must be reported by the device" but is seems like the Traccar starts counting it

Now my question - Is that Engine Hours equal to Idling time?

I am waiting for more explanation if I was wrong

regards.

Engine hours are calculated from the time ignition is ON.

So it is the duration where ignition is ON, within the total stop duration right?

Not sure what you mean by total. It's calculated for each stop.
