        abstract = {The Internet of Things (IoT) has fundamentally transformed residential environments into intelligent, connected ecosystems. This paper presents a multi-layered, edge-computing-enabled smart home automation system built on Raspberry Pi 4 and Node MCU ESP8266, integrating MQTT, Wi-Fi, Zigbee, BLE, and Z-Wave protocols. A seven-layer security framework employing AES-256 encryption, JWT multi-factor authentication, RBAC, and Hyperledger Fabric blockchain is implemented and evaluated. The prototype achieved local command response of under 100 ms, 99.4% uptime over a 30-day test, and 32% lighting energy savings versus manual control, validated across five performance dimensions. The global smart home market trajectory from USD 127.8 billion (2024) to USD 537.3 billion (2030) underscores the critical importance of scalable, secure, and interoperable IoT architectures.},
