Required and Extra fields:

- Device Auto Provisioning: checkbox with same function as "Application Auto Provisioning" but with DevEUI;
- Application*: same function as "Preset Application" field of MQTT Broker;
- Name*: the Name of the Websocket Client;
- URL*: the URL of the Websocket Client.

Structure:
Differently from MQTT Protocol, Websocket's message isn't split into two parts, infact its directives are represented by a JSON. To recognize the type of the message, there's a JSON field called "Command" that describe the action. The Command description format depend from the Server. ResIOT has some pre-configurated models but if you want to use your own server you have to set the JSon Data Patterns table in Websocket Edit based on the documentation.
