What does the "Last Update" column in "Devices" panel mean?

I have this device that stops sending messages as soon as I turn off the ignition. I can confirm it's behaving like this.
I checked the server log to confirm nothing is being received (even if filtered) by the server.
The web report also confirms that no new points are being stored on the server.
The "State" panel also confirms the last message received was many minutes before.
But the "Devices" panel always show "0 minutes" on the "Last Update" column, and the icon is always green.

So my question is, what triggers the "Last Update"? Is there any way I can check if there is any underlying communication going on?

How did you confirm "nothing is being received"? It seems like you are only looking at locations.

You are right. For some reason. the device keeps sending "I'm alive" messages without location.
