Still a little bit rough around the edges, but there's now a plugin to integrate Signal K with the Meshtastic LoRa mesh network. What now works: * Updating Meshtastic node position from Signal K * Sending Signal K alerts as texts to a configured set of Meshtastic nodes * Sharing telemetry (wind, temperature, etc) to the mesh * Controlling digital switching with text messages https://github.com/meri-imperiumi/signalk-meshtastic#readme
