I need a sleek, mobile-first interface that hooks into my smart-home ecosystem and streams each device’s status the moment it changes. The back-end APIs are already in place (REST with optional MQTT for push), so your task is purely the front end: design, build, and wire up a responsive dashboard that can poll or subscribe for updates and paint them on screen without perceptible lag. Core requirements • Mobile optimisation is mandatory; the UI must feel native on both iOS and Android, whether you choose React Native, Flutter, or another cross-platform approach. • Real-time monitoring is the single focus—lights, thermostats, locks, and sensors should update instantly, with clear visual cues of values • Clean, modern visuals that suit a consumer smart-home app, including dark-mode support. Deliverables 1. Source code with clear component structure and comments. 2. Build instructions plus one signed release APK/IPA for test install. 3. A brief README explaining how the app discovers devices and handles live updates. 4. Short demo video (screen capture) proving real-time refresh against our staging server. Acceptance criteria • Device state changes reflected in under one second. • No crashes or major UI glitches during a 30-minute continuous run. • All text and colours pass basic accessibility checks (WCAG AA). If you have questions about our endpoint schemas or sample payloads, let me know and I’ll share them right away.
