In the doco for the traccar component: https://www.home-assistant.io/components/traccar/
It talks about getting traccar events to fire:
device_moving
(string)(Optional)deviceMoving event.
command_result
(string)(Optional)commandResult event.
device_fuel_drop
(string)(Optional)deviceFuelDrop event.
geofence_enter
(string)(Optional)geofenceEnter event.
device_offline
(string)(Optional)deviceOffline event.
driver_changed
Where in home assistant would these show up? I had a look inth edev tools and it can subsccribe to an event. And looking at the traccar documentation it says something about:
as soon as Home Assistant receives those events from the platform, they will be fired as traccar_device_overspeed and traccar_device_fuel_drop. NOTE Specify all_events if you want to import all events
So I tried subscribing to traccar_device_online but no joy.
