NITROGEN MESSAGING

var message = new nitrogen.Message({ type: '_lightState', body: { on: false } });

var message = new nitrogen.Message({ type: '_lightLevel', body: { ambientLight: 51 } });

NITROGEN MESSAGE{

"body":

DEMO

Sending Telemetry to Nitrogen

COMMAND & CONTROL Nitrogen enables sending messages or subscribing to message streams

Any device with permission can send a message to a specific device

Any device with permission can subscribe to the message stream of a device

NITROGEN COMMANDMANAGER The CommandManager enables interrogation and execution of commands

for a device.

CommandManager should be sub-classed for the specific implementation.

Sub-classes must override five (5) functions: isRelevant() isCommand() obsoletes() executeQueue() start()

IMPLEMENTING COMMANDMANAGER isRelevant

Should I care about the message?

isCommand Do I need to execute the message?

obsoletes Do I care any more? (e.g. have I already processed this)

executeQueue Do whatever needs to be done based on the message

start Get things going

PERMISSIONS Permissions enable control over which Principals can interact (or not) with

other Principals

Permission Types admin view send subscribe

Permissions enable explicit authorization control n2 permission add --action subscribe --authorized true --issueTo <PRINCIPAL ID> --principalFor <PRINCIPAL ID>
