Build scalable, secure IoT devices for your home automation system using advanced tools, protocols, and frameworks Free with your book: DRM-free PDF version + access to Packt's next-gen Reader\* Key Features Master automation logic using YAML, Jinja2, Node-RED, and scripting in Home Assistant Build custom ESP32 IoT devices, sensors, GPS modules, and cameras with ESPHome and MQTT Secure and expand your smart home network using Zigbee, Golioth, and other best practices Book DescriptionAdvanced smart home setups often require more than standard configurations to achieve performance, security, and flexibility. This book helps electronics engineers and advanced home automation enthusiasts extend Home Assistant with deeper control over devices, networks, and integrations. You’ll begin with performance tuning and advanced YAML and Jinja2 configurations, then move on to secure network design using Zigbee and cloud integration with Golioth. You’ll build custom IoT devices with ESPHome, use MQTT for communication, and develop ESP32-based touchscreen displays and camera systems. By the end of this book, you will also have covered advanced automation patterns using Node-RED and AppDaemon, along with AI-driven techniques to analyse user behaviour and optimize automation workflows. Written by an expert with over 25 years of experience, this book provides practical methods to design, secure, and scale modern smart home systems. \*Email sign-up and proof of purchase requiredWhat you will learn Implement complex YAML and Jinja2 automations in Home Assistant Secure your home network using VLANs, segmentation, and firewall rules Deploy and manage Zigbee networks with Zigbee2MQTT and ZHA Develop custom ESPHome firmware for sensors and touchscreen displays Use MQTT tools to build and test device communication flows Integrate cloud IoT platforms such as Golioth with Home Assistant Create interactive dashboards and camera-based smart systems Design AI-based automations to learn and suggest behaviors Who this book is forThis book is for electronics and embedded engineers working with advanced sensors and automation, as well as IT and networking professionals securing and scaling smart homes using Home Assistant.
