 - Device events are streamed in real time into Watson IoT
-- In addition to the real time event pass-through, every 5 minutes the current state of all devices is captured and reported to Watson IoT
 
-State updates are published to Watson IoT in real time and captured every 5 minutes even when no state changes have occured.  The events sent by any device are defined by it's capabilities.  Watson IoT eventId's match 1:1 with SmartThings capabilities, all events are sent in JSON format.
