Geofence of Device

Hello friends,

is it possible to create Geofence around a moving Device, so if another device come into Geofence or go out of it I can trigger something.

Thanks in advance

For security reasons it will be a huge capability

Not possible currently.

Will it be possible any time in the future ?

This huge capability will cost you a huge amount of resources on the server. Because it will have to calculate the distance between all tracked devices. This feature should be an option or a plugin.
