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 […]
NMEA 0183 to Home Assistant: Wi-Fi, Signal K & Serial
đź”— 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 […]
Connect NMEA 0183 to a Raspberry Pi
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
Connect NMEA 2000 to a Raspberry Pi
Connecting your boat’s NMEA 2000 (N2K) network to a Raspberry Pi is easier than you might think. With Home Assistant plus either a low-cost ESP32 CAN transceiver (wireless) or a USB-CAN adapter (wired), you can stream instrument data to custom dashboards, create smart alerts, and automate tasks — all locally and on a budget.
