When writing the code for an Edge Action, you will usually base your logic around the value from the incoming Event being Observed such as the value of a sensor reading.

When an Event is received in an Edge Action, the event parameter contains the Event's data:

function(event) {

}

The Event is received as a JSON object on the Octave Edge device and contains the following fields:

{
  "value": value,
  "timestamp": 1582827837.235676
}

• value: the Event's data (e.g., a sensor reading).
• timestamp: The date/time when the event was received.

The JavaScript in an Edge Action can read this information via the event parameter. For example, the following code reads the value of a light sensor:

function(event) {
  var lightReading = event.value;
  // ...
}

After reading the Event's value, you may then want to perform some logic and then set a value. For additional information see the Edge Action Runner Reference.
