HAPCES

HAPCES is a system designed to increase interaction variety for the home automation platforms via a REST API and Android Timer App.

API

• Provides REST endpoints and resources that integrate with a platform to simplify inspection and control of connected smart-devices
• Supports platform authentication
• Endpoints are validated (e.g., URL parameters)
• Allows testing without platform via mock data
• Automatically generates interactive documentation
• Includes a unit test suite for all endpoints
• Demonstrates API usage via a command-line client to inspect or toggle on/off all connected switches

Timer App

• Integrates with the API to provide timed-control of a home automation platform’s smart-devices
• Integrates with home automation platform
• Provides users with a timer via account creation
• Smart-devices can be linked to the timer
• Timer duration and label are customisable
• Simple design consistently incorporates Material Design
• Lists devices and their current state
• Achieved an above average System Usability Score via usability testing
