Ignition event changes by itself

Hello!
Have an issue with a tracker.
The ignition settings set to:
ignition? false: true
The tracker has been constantly triggering the event "Ignition On" and "Ignition Off" with delay in a minute or so.
Can you please tell me what to do and how can I fix it?

Your screenshot doesn't match your original post and neither of those make any sense to me. Let's start with logic you want to use first.

Thanks for the answer
I will write more precisely

Hello Anton!
First of all I want to say thank you for your job

The last version of the Traccar is installed on the Ubuntu 20 LTS.
The tracker is connected via protocol Teltonika, it works great, but doesn't show ignition status at the software.
When the engine is started or stopped only the variable "Di1" at the tab "STATE" from 0 to 1, but the variable "ignition" stays the same.
Also there is no data at the tabs "events" and "reports".
I've tried to use different attributes, but it hasn't helped. Which settings or attributes are needed for the "Ignition" feature?
Could you please help me to connect this feature to the Traccar system?

The expression should probably be just

di1 ? di1 > 0 : null

Thanks for your help

Can you please help me, where I can find the full list of all available attributes?

There's no list of all possible attributes, but you can see the ones that your devices report in the status panel.
