Reliable way of location tracking

How does presence detection work when multiple “detectors” are used?

It seams to me it’s just last report = current state?
It would be nice if it could be configured to work like this:
Any one detector reports home => HOME
All detectors report away => AWAY

I think you can achieve this by placing all of your “detectors” in a group. The group’s state will remain “home” until the last device that is tracked is marked as away.

So, like this?

FAMILY (GROUP)
– Person 1 (GROUP)
---- Phone NMAP
---- Phone IOS APP
– Person 2 (GROUP)
---- Phone NMAP
---- Phone OWNTRACKS

Yes, though you can merge the nmap and OwnTracks trackers, see here, so that you’ve only one tracker for that person.
