The "Smart Home Assistant Integration Platform" 
Facilities under Smart Home Assistant control: (1) Motorized window.
Facilities under Smart Home Assistant control: (2) Drying Rack.
Facilities under Smart Home Assistant control: (3) Water leakage detection and water tap control.

The Smart Home Assistant Integration Platform (SHAIP) represents a comprehensive solution that seamlessly integrates LifeSmart lighting switches and custom-designed WiFi-based IoT sensor nodes to facilitate the control of a range of home appliances, including: 1. Motorized windows (with functionalities for opening, closing, and stopping); 2. Drying racks (with controls for raising, lowering, stopping, and toggling the integrated lighting); 3. Water leakage detection and automated water tap control; and 4. Lighting management.

This system encompasses both hardware and software components. The hardware architecture is founded upon ESP32 IoT modules equipped with customized firmware, while the software leverages the widely recognized open-source Home Assistant platform to ensure robust and flexible operation.

Under the guidance of the Health & Social Care Team at the Industrial Centre of The Hong Kong Polytechnic University, two student assistants successfully developed the complete user interface and backend for the Home Assistant segment of this system. Their work was implemented in the Living Lab at the Elderly Resources Centre, Hong Kong Housing Society.

The implementation of this platform significantly enhances the convenience and accessibility of age-friendly home environments for elderly residents and their caregivers. Additionally, the system is capable of storing data from various IoT devices, thereby providing valuable resources to support ongoing research initiatives.
