Smart Boat 16: Connect NMEA Instruments to Home Assistant

Published at : 23 Dec 2025

Join me as I guide you through the intricacies of marine instrument integration for our Smart Boat. Curious about the distinctions between the NMEA 0183 and NMEA 2000 networks? I've got you covered. I've personally developed the Smart0183 integration, a tool that seamlessly connects the NMEA network to Home Assistant, creating and populating entities automatically from your instrumentation data.
