MQTT data manipulation

[leif_klasson@hotmail.com]

Hi all,

The eagle has landed ... being an EE engineer I should have cached that the server wasn't listening. 

When I came home today the first thing I did was to change the port to one that was allready defined, I took 55558 (OPnotifications) and the magic happened.

Hi, I can send you an example of UDP package I have sent from EspEasy to Openplotter via UDP. In the delta message, you also need to set source simply.
And no, you only need to send delta as far as I have seen.
See also manual for SignalK, go down to delta:
http://signalk.org/specification/1.0.0/d...model.html
Example from manual (for vessel, use vessel.self instead):

Code:

{
 "context": "vessels.urn:mrn:imo:mmsi:234567890",
 "updates": [{
   "source": {
     "label": "N2000-01",
     "type": "NMEA2000",
     "src": "017",
     "pgn": 127488
   },
   "timestamp": "2010-01-07T07:18:44Z",
   "values": [{
     "path": "propulsion.0.revolutions",
     "value": 16.341667
   }, {
     "path": "propulsion.0.boostPressure",
     "value": 45500.0
   }]
 }]
}
