-Trigger all objects with the given connected-id. The trigger is stateful
-and retains state per connected-id.
+Trigger all objects with the given connected-id.
+
+When the state argument is omitted the trigger is stateful and retains an
+internal state per connected-id. There is a limitation to the use of this: The
+state won't be changed when the connection is triggered by other triggers.  So
+be careful when triggering the connection from other objects.
+
+When a state argument is given it should be either 0 or 1. 1 will 'push' the connection
+and 0 will 'release' the connection. This is useful for example when you want to
+let a npc control a door.

+Trigger all objects with the given connected-id by 'releasing' the connection.
