Abstract

Noah MQTT is an open-source Internet of Things (IoT) project. A tool for integrating Growatt Noah 2000 home batteries with Home Assistant via MQTT, enabling monitoring and control of your energy storage system. noah-mqtt is a standalone application designed to retrieve data and metrics from your Growatt NOAH 2000 home battery used in balcony power plants. It publishes this information to an MQTT broker, making it easily accessible for Home Assistant or other applications. It is built using Go, MQTT. The complete source code is publicly available on GitHub under the Apache License 2.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

noah-mqtt is a standalone application designed to retrieve data and metrics from your Growatt NOAH 2000 home battery used in balcony power plants. It publishes this information to an MQTT broker, making it easily accessible for Home Assistant or other applications.

The application features Home Assistant auto-discovery, allowing your NOAH devices to be automatically recognized and integrated with Home Assistant via the MQTT integration.

Adjust these settings to fit your environment and requirements.

2. Objective

A tool for integrating Growatt Noah 2000 home batteries with Home Assistant via MQTT, enabling monitoring and control of your energy storage system.

This project demonstrates how Go, MQTT can be applied to a real-world Internet of Things (IoT) problem.
