I have set up virtual device trackers for vehicles that “copies” the location of the person driving it (via their person device trackers), while they occupy the vehicle[1]. As a part of that functionality, on becoming unoccupied, this virtual device tracker will wait for one more update (as we are assuming a location provided /after/ leaving the vehicle is more useful than the last one received).
To help this process, I want to request an accurate location from the HA companion app of the driver when they leave the vehicle, rather than waiting for the next non deterministic location update.
