Lutron LEAP Smart Hub and Proximity sensor

I have OpenHAB 3 running. On it I have TPLink tcp/ip electrical plug controllers, some Phillips HUE bulbs and Phillips HUE hub, I also have Lutron Caseta light switchs / remotes (These are AWESOME as they work flawlessly with my old wiring).

One of the functions I would like to make use of is the Lutron sensing that I have come ‘home’. When this is triggered I would like a script to run on OpenHAB. My problem right now is trying to find a way in OpenHAB 3 to sense that the Lutron hub has detected me.

Anyone have any ideas on this?
