By using the configuration option "use_events:yes" in the device_tracker section,
only 'enter'/'leave' events are considered to calculate the state of a tracker device.
The home zone is defined as the owntracks region 'home'. Other regions may also be defined, the name of
the region is then used as state for the device. All owntracks regions, the 'Share' setting must be enabled in the app.
