Hide ignition icon for specific devices

Is there a possibility to hide the ignition icon for specific devices?
We use the Mictrack MT710 device for personal and pet tracking where no ignition indication is needed for the user interface. It actually does not even apply at all.

You can use computed attributes to clear any attribute by passing null value.

I'm not sure, but i think you mean "ignition" in the info white popup that appears when you click on a device. If you refer to that "Ignition", you can hide it just removing it from the attributes on your popup (in your account preferences).

If you really mean you want to discard saving of ignition attribute completely, then as Anton told you : you need to use Computed Attributes to convert ignition 0 or ignition false to NULL.

Greets.

Sorry, was not following up on this topic. Let me jump in again.
Would it be something like that for gt06 to hide the ignition icon fully:

Ignition
ignition ?  1 : null
Boolean

and

Ignition
ignition ?  0 : null
Boolean

Cheers,

No, you just need to return null.
