Power off/on alarm

Hi. I have a problem with this event because I need the event as "Engine Off" or "Engine On" (now is registered as "Power off alarm" or "Power on alarm") to check engine hours in the summary report.
The devices are TK103A

To get hours you need ignition value. If your device doesn't report it, you can try to reuse power on/off events using computed attributes.

Here are two examples I established for two different devices:

Thanks Anton and Visiondrive!

I need ignition On and Off so... Do you think the following computed attributes are correct?

Looks correct. You also need to configure attributes copying because ignition needs to be present in every position.

Great! Thanks!
Are you talking about enable this?

Yes.

Thank you very much!
