Creating a sailboat-tracker - bkkrdbkstn - 2017-08-09
I'd like to create functionality which sends my GPS position together with the current SOG and Time to some kind of dashboard. Then the dashboard only shows a map with my full track (past few weeks? preferably as much as I can, but then the dashboard also needs to be able to specify the max length to avoid clutter..). By clicking the track, or actual in-between positions the SOG is displayed.
I think I can achieve this, but for now I don't have any experience in node-red, MQTT, whatsoever. What is the best place where I can start? Or, since I think it's a bit of basic use in these kind of applications; are there any examples/tutorials online? I havent been able to find some basic ones, but maybe I'm just searching the wrong words.
My brain now says something like this; Openplotter gets the GPS position, SOG and Time over one of my NMEA connections. Node-red handles some kind of interval-timing, so I only have to send it in intervals of 30 minutes. It also checks whether I have an internet connection and then sends the data since last connection.
Then the dashboard is able to receive this data, plot the intervals on a map (preferably one in which I can specify the map, thus Gmaps, but also OSM and other WMS). Now, should the map take into account drawing the paths between the positions, or should I already had have handled this before uploading?
Is there anyone who has a live demo, or some tips to point me into the right direction?
