Oil Pressure monitor with ESP32, INA219

đź”— Full Guide · Transcript Build a digital oil-pressure monitor using an ESP32 “remote hub,” an INA219 board over I²C, and Home Assistant/ESPHome. This guide follows every technically relevant step from the video: soldering the INA219, wiring to the ESP32, tapping the existing oil sender’s “Gauge” terminal, adding INA219 in ESPHome, calibrating volts→bar from two […]

NMEA 2000 to Home Assistant: ESP32 & USB-CAN

đź”— Full Guide · Transcript Turn your boat’s NMEA 2000 (CAN bus) into live dashboards, alerts and automations in Home Assistant. This guide covers two integrations you can add via HACS: 🚦 Smart2000 ESP — Wireless bridge using an ESP32 + CAN transceiver (place it near the N2K backbone, stream to your Raspberry Pi over […]

Connect NMEA 0183 to a Raspberry Pi

Boat monitoring interface showing aggregated NMEA navigation and system metrics

Connecting your boat’s NMEA 0183 data to a Raspberry Pi is straightforward with Home Assistant and my menu-driven integrations. Choose TCP/Wi-Fi (no extra cables, works with Signal K or Wi-Fi gateways) or go USB Serial (RS232/RS422) for a robust wired feed. Either way, you’ll stream instrument data into custom dashboards, create alerts, and build automations
