The ha-smart2000esp integration lets Home Assistant receive live NMEA 2000 (CAN bus) data over Wi-Fi using an ESP32 with a CAN transceiver. Place it near your N2K backbone and stream engine data, tank levels, wind, depth, GPS, and other marine instruments directly into your dashboards. Perfect for Raspberry Pi-based central marine computers and boat automation projects where running cables is difficult or you want a flexible, wireless solution.
