The Libri GmbH The Complete Open Source Smart Home Guide

Build a Private, Flexible Smart Home Using Open Technologies You ControlA modern smart home should not be limited by separate applications, locked ecosystems, or constant dependence on outside services.A better approach is to create a system where your devices communicate together, your automations run reliably, and your important household functions remain under your control.The Complete Open Source Smart Home Guide teaches you how to design, build, and maintain a flexible smart home using proven open technologies.This practical guide takes you from understanding smart home architecture to creating a complete connected system with sensors, lighting, automation, dashboards, and custom devices.You do not need previous experience with advanced programming, electronics, or networking. Each technology is introduced individually before being combined into a complete working environment.Inside this book, you will learn how to: - Understand the architecture behind a modern smart home- Compare local, cloud-based, and hybrid approaches- Plan your network, hardware, device placement, and installation strategy- Install Home Assistant on a Raspberry Pi- Understand integrations, devices, entities, dashboards, and automation logic- Create a reliable MQTT messaging layer- Work with brokers, topics, payloads, publishers, subscribers, and message delivery- Build visual automation workflows with Node-RED- Create reliable Zigbee networks using coordinators, routers, and end devices- Connect ESP32 and ESP8266 boards for custom sensors and controllers- Use Tasmota firmware for compatible locally controlled devices- Build addressable lighting systems with WLEDThe book follows a simple design philosophy: Choose the right technology → Build one layer → Test it → Connect the next layer → Expand carefullyYou will learn why each technology exists, when to use it, and how information moves from a physical sensor to a final automated action.By the end, you will understand how to create a smart home where: - Sensors collect information- Networks move data- Controllers make decisions- Automations create useful behavior- Devices respond locally and reliablyWhether you are starting with a single Raspberry Pi or planning a complete household automation system, this guide gives you the foundation to build a smart home that is understandable, maintainable, and independent.Create a connected home that works the way you want-not the way a manufacturer decides.
