Geofence not being reported

Hi,

I have the latest traccar server running from dockerhub and I notice that the geofenceIds field is not being updated for any of my trackers.

Is there something I need to do to get this to update?

I have several geofences created but trackers moving in and out of them dont have a value wether they are in or out of them. The value is always blank

Thanks!

Have you linked geofences to your devices?

No, I dont think I have. Is there are description to do this in the documentation?

Yes, of course:

Thanks, your comment pointed me towards groups so all sorted now
