Is SignalK json available directly from device over http/https?

[kevrmParticipant]

Is there a direct api to call for the JSON, ie/ REST GET

Hi Kevrm,

Absolutely, there are two methods to get Signal K JSON from iKommunicate, either via an HTTP RestAPI call (currently no support for HTTPS but watch this space!) which is good for polling data or by opening a websocket to constantly stream Delta Message updates as new NMEA data is received and converted.

A typical RestAPI call like http://192.168.0.80/signalk/v1/api/vessels/self/propulsion

Will return the following Signal K JSON about the status of the Engines, in this case a single Yamaha outboard connected to iKommunicate via the Yamaha NMEA2000 interface.

{
  "0": {
    "oilPressure": {
      "value": 296000.000000
    },
    "engineTemperature": {
      "value": 322.000000
    },
    "alternatorVoltage": {

    "runTime": {

    "coolantPressure": {

    },
    "revolutions": {
      "value": 11.066667

    "boostPressure": {
      "value": 38900.000000
    },
    "engineTrim": {
      "value": 29
    }
  }
}

Note that all Signal K values are in SI units i.e. Pascals, Kelvins, Hertz, etc.

Best regards
PAUL
