A bridge over (not) troubled waters: Collecting marine data from your couch
summary
A homebrew telemetry stack called Anode homebrew chart plotter runs on a Raspberry Pi with a RAK Meshtastic node and a Yacht Devices NMEA 2000 bridge, ingesting Zigbee, Bluetooth and NMEA sensors into Signal K → MQTT → Home Assistant via Mosquitto and Tailscale. It reports cabin and bilge temperatures and humidity, battery state, and boat GPS on live maps for a 27‑ft Tollycraft kept 4.5 miles away, and uses adaptive heater/dehumidifier control; a Meshtastic mesh node is planned to keep telemetry when marina Wi‑Fi drops.
