Authenticate as an Operator and read a Thng object:

var operator = new EVT.Operator(OPERATOR_API_KEY);
var thngResource = operator.thng('{thngId}');

Subscribe to property updates of a particular Thng:{

Publish property updates:'key').publish(value);

Create an action:


Update a Thng:

  name: 'My new cool name'

Unsubscribe to a subscribed topic:;


Check all the available subscriptions on the EVRYTHNG Pubsub documentation.
