signalk-raymarine-autopilot

signalk-raymarine-autopilot signal is composed of 2 modules:

• A graphical interface that emulates a Raymarine remote control
• A back-end API described below.

API

All messages to plugin are done as POST requests which take a map as input in the form:

{
  "action": "someAction",
  "value": 10
}

The POST should be sent to /plugins/raymarineautopilot/command

Advance Waypoint

{
  "action": "advanceWaypoint"
}

Set Autopilot State

The value can be auto, wind, route, or standby

{
  "action": "setState",
  "value": "auto"
}

Change Target Heading or Wind Angle

The value is in degrees and is the amount to change. So when in auto at a heading of 180, a value of -10 will change the target heading would be changed to 170

{
  "action": "changeHeading",
  "value": 1
}

Change Target Heading or Wind Angle by key

The value is a direct key (+1, +10, -1, -10, -1-10, +1+10). The key +1 add +1 degree to heading, +10 add +10 degree... The special key -1-10 and +1+10 is dedicated to take a tack to port or starbord.

{
  "action": "changeHeadingByKey",
  "value": "+1"
}

Take a tack to port or starboard

The value is port or starboard. This command must be send only when your pilot is in auto or wind mode.

{
  "action": "tackTo",
  "value": "port"
}

Silence alarm

This command silence a Raymarine alarms. You can silence alarm directly by the numeric code or by a signal k notification path. This command does not silence a signal k notification. It is your Raymarine equipment that receives the acknowledgement command and returns a new notification status on the NMEA2000 bus with the normal state value. See the code in index.js for the complete list of raymarineAlarmGroupCodes and alarmsId keys / values.

In acknowledgement by the numeric code, the value is :

{
  "action": "silenceAlarm",
  "value": {
    "groupId": "0x01",
    "alarmId": "0x47"
  }
}

In acknowledgement by signal k notification path, the value is the path you receive in your websocket :

{
  "action": "silenceAlarm",
  "value": {
    "signalkPath": "notifications.autopilot.PilotWarningWindShift"
  }
}
