Complete Engine Monitoring for Boats
Complete System Build a complete engine-monitoring dashboard with 8 gauges: 4× Temperature (DS18B20) + 1× Tachometer (RPM) + 1× Oil Pressure + 1× Fuel Tank Level + 1× Engine Hours. All sensors feed a single ESP32 running ESPHome, visualised in Home Assistant. 4× Temp gauges 1× Tachometer 1× Oil pressure 1× Tank level 1× Engine […]
Digital Engine Tachometer with ESP32 and Optocoupler
🔗 Full Guide · Transcript Build a simple, accurate digital tachometer for your engine using an ESP32 “remote hub,” a ~$2 optocoupler, and ESPHome/Home Assistant. This guide covers wiring (alternator tacho → optocoupler → ESP32), ESPHome setup with a pulse counter, RPM calibration from real data points, optional engine-hours and engine-active entities, and a dashboard […]
Oil Pressure monitor with ESP32, INA219
🔗 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
🔗 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 […]
NMEA 0183 to Home Assistant: Wi-Fi, Signal K & Serial
🔗 Full Guide · Transcript Build a central boat computer with Signal K (TCP) or USB (Serial) — no YAML. I’ve built two integrations to streamline NMEA 0183 → Home Assistant. They aim for a near plug-and-play experience: no YAML, menu-driven setup, and full sensor autodiscovery via HACS. 📶 Smart0183 TCP (wireless) — TCP/Wi-Fi connectivity (works with Signal K and […]
