Help Using Computed Attributes

Hi everyone,
I'm looking for someone who understands how to use computed attributes in Traccar and can explain them clearly with a real-world example.

I’ve read the documentation, but I’d really appreciate a practical explanation or use case to better understand how to configure and apply them correctly.

Thanks in advance!

What's wrong with the examples in the documentation?

I used this computed attribute, but it's still showing an error.

Are you trying to remove tampering or keep it?

Yes, I’m trying to remove the tampering alarm

Your expression does completely opposite. You should do something like this:

alarm == 'tampering" ? null : alarm

After correcting the computed attribute expression, how do I link it to the device?

The same way you link anything else.

Thank you! I had to restart the server because it wasn't showing up.
