The Room Control System is a next-generation, open-source IoT-based automation platform designed to control and monitor electrical appliances in real-time. Unlike traditional smart home systems, this solution is cost-effective, cloud-independent, and fully customizable—empowering users with unparalleled control and security over their smart environments.
Built on a modern tech stack leveraging MQTT, WebSockets, SQLite, and Express.js, this system delivers seamless automation, real-time feedback, and AI-driven voice control without requiring proprietary apps like Alexa, Google Home, or Blynk IoT.
