Some very good ideas. The units can be flagged as mobile, for instance the A3 is a fixed unit, yet the first 10 units installed on buses in Cluj Napoca function as mobile units. The busses also provide real time GPS coordinates via separate HTTP Posts. So this would be possible for the KIT1 as well.
Also I’m working on a new frontend, that will show mobile units separately. There there is also a switch to toggle offline units off.
Finally, we’ll slowly move to dynamic IDs, and that implies the need for an expiration time before an unused ID can be re-assigned, taking the unused stations off the map automatically.
Lots of lines of code for all this, but getting there.
