This paper presents the development and implementation of an advanced smart home management system based on the Internet of Things (IoT), cloud infrastructure, and a multiplatform user application. The system integrates devices, sensors, and services into a unified intelligent environment that enables real-time monitoring and control of ambient conditions. The system
architecture is modular and consists of three main components: an IoT device based on an ESP32 microcontroller with a DHT22 sensor, a serverless backend implemented using Azure Functions and a MongoDB database, and a Flutter application available across multiple platforms (Android, iOS, and web).
