is it possible to change $position.address to last stopped address
You would have to change it in the code.
currently some times position.address not show up on notification
It probably means your geocoding provide failed.
I'm using custom geocoding and the problem is some time device moving notification trigger on out of that red circle
<entry key='event.motion.speedThreshold'>1</entry>
will not help
Not sure I understand the problem.
