Smart Trigger Execution Framework in IoT Gateway Applications for Home Automation

This paper presents a trigger-based execution framework designed to enhance the responsiveness, flexibility, and reliability of Zigbee-based home automation systems. The framework enables users to define automation triggers—including conditions and corresponding actions-via a mobile application, which are then centrally managed by a local gateway. The gateway processes incoming data from Zigbee sensors in real time, evaluates trigger conditions, and executes actions by interfacing with Zigbee[1] devices. A relational database schema supports structured storage of triggers, conditions, actions, and device metadata. Additionally, the integration of the Paho MQTT [2] client within the Zigbee[1] System-on-Chip (SoC) application allows for direct MQTT[2] communication, improving system autonomy and reducing latency. This architecture minimizes cloud dependency, enhances data privacy, and facilitates dynamic device control, making it a robust and future- ready solution for smart home automation. The proposed system is particularly suited for user-centric environments where intelligent, local decision-making is critical.
