FR: Set speed to zero after period of no location updates #94
Description
A usual reason why a device loses the ability to send location updates is because you enter a building.
The current behaviour of composite is to not recalculate speed until a new update allows it to. In the above case, this may be misleading as your speed would be set to a positive value while you're actually still, until you leave the area of no reception.
This request is to automatically set the speed sensor to 0 (or unavailable) after a period of inactivity.
There might be a false case eg of entering a tunnel where the speed would be set to zero with this new feature. However I think it's better to set to a value best representing unknown than to keep propagating the last known value (and also in the tunnel scenario it should be quickly resolved as we tend to spend less time in a tunnel than a building).
I am currently using an automation to fake an update after a time of idle, but it would be great to see this as a native option.
