Some people have asked me why I don't use OpenPlotter for this, and the simple reason is performance. This creates a powerful computer that will plug directly in to your NMEA 2000 network where it will get power and essentially be self sufficient. We'll also be installing Grafana and Influx and creating a test dashboard and graph. I will be installing various Signal K plugins I consider to be essential to effectively use the server, and those related to Grafana and InfluxDB. I will be using a Raspberry Pi 4 with the PICAN-M add-on board that I discuss in the article below. If you're using another operating system, you'll have to adapt some of these steps. I will be using a Mac for all of my steps. If you're doing it on some other system, you will have to check your permissions. Most all commands require sudo privileges as well, which if you are using the default “pi” user isn't an issue. You need to have some skills with computers to be able to download software, issue terminal commands, and understand the general parts of what I'm doing below. This article goes through my recommended steps to set up the base operating system and common programs for those items. Signal K is very powerful, but most people I talk to want to go a step further and have Grafana graphs and dashboards, along with other plugins and features. With the advent of streamlined Raspberry Pi + NMEA 2000 hardware, building a dedicated Signal K server has never been easier.
