YourStayHub is a web-based smart automation platform tailored for short-term hospitality environments such as Airbnb properties, guesthouses and hotel rooms. The system provides guests with full, intuitive control over a wide range of smart devices—such as lighting, HVAC, water heaters, blinds, and security systems—via a web-based responsive interface, with no app installation or technical setup required. Moreover, guests can create multi-step scenes with customized device behaviors—including delayed actions—, schedule time-based automations, monitor real-time environmental and energy data, and access an integrated security panel that supports “smart” alarm states and live CCTV feeds. Access is granted only for the duration of the reservation and is automatically revoked upon checkout. YourStayHub is compatible with a wide range of IoT devices and communication protocols, offering vendor-independent, unified control through a single platform. Designed with a user-centered approach, it bridges the gap between traditional smart home automation and the specific needs of hospitality environments. It empowers non-technical users to manage smart spaces independently, securely, and efficiently.
