This is a large number which uniquely identifies a trigger or action.  Any trigger or action that shares the same eventid will be linked such that activating the trigger will send this eventid across the network and cause the linked actions.

More details:

  • An eventid is 64 bits, and is represented as hex pairs, eg:
  • All nodes have preconfigured unique eventids associated with their inputs and outputs.
  • In many cases eventids are used in pairs assiated with an input or output, one representing a transition to active/1/high and the other a transition to inactive/0/low.
