Help detect ignition off with TK303-Coban equipment

With my TracCar6 configuration onwards, the platform doesn't detect the "ignition off" status; it only detects the "on" status. I have it configured for Alarm and Ignition as well, adding calculated attributes.

What would be the expression for "off"? ignition ? "powerOff" : null ???

Probably what you want to do is ignition ? "powerOn" : "powerOff".

thanks for the help.
