Victron BLE → MQTT → Home Assistant (No VRM) – Full Offline Pi4 Setup w/ Guide

curtalfrey · August 8, 2025, 12:42am

Hey all,

I’ve built a fully offline, headless Raspberry Pi 4 integration that scans Victron SmartShunts and MPPTs over BLE and publishes them to MQTT for use in Home Assistant. It’s ideal for setups without a Cerbo GX or cloud connection.

# Victron BLE to MQTT Integration Setup Guide

This guide walks through the complete setup of a Raspberry Pi 4 running Raspberry Pi OS Lite to scan Victron BLE devices (e.g., SmartShunts, MPPTs), publish the data to MQTT, and integrate with Home Assistant. No GUI required. Copy-paste friendly.
