How SignalK Demo - How its Set up and How to View Data
This demo is running live from our boat (SNAFU II). The boat is on a swinging mooring in the UK - systems powered by solar panels - access via 4G and the VPN. If you are interested in viewing
your own boat systems via a VPN, all the software is free and Open Source. We charge a small subscription to enable users to use the VPN. Note that this is a VPN
which allows you private access your boat systems, not a VPN to use from the boat for privacy whilst browsing.
To view the feeds, select Data Browser
from the menu on the left. This will show you a table of feeds,
- Value - updated every 2 seconds
- Date/Timestamp - updated on every read i.e. every 2 seconds
- Source - this is named "skippersmate" and is running on SNAFU II
Signal K is an open data format allowing you to utilise the data from
a wide range of standard sources. For the purposes of the boat we have, or plan to have, inputs from instruments using
NMEA2000, NMEA 0183 and Modbus. Please Google for information about SignalK - it is both clever and complex so we won't be
discussing the details here.
We currently have :
- NASA BM1 - Bluetooth
- Epever Triron MPPT solar panel controller - RJ485 and Modbus
