dilums/gemini-3-smart-home-app — reverse-engineered prompt

Build me a polished smart home dashboard web app. I want it to feel like a futuristic home control center, with a beautiful dark interface, cards for different rooms, and simple controls for common devices like lights, thermostat, locks, cameras, plugs, and speakers. The main screen should show overall home status, weather or indoor temperature, energy usage, security status, and a quick way to toggle devices on and off.

Make it responsive so it looks good on desktop and mobile. Add realistic sample data so I can click around without connecting real devices. Keep the code clean and easy to understand, with reusable components and TypeScript types. It doesn’t need real hardware integration yet, but structure it so services could be connected later. Use smooth interactions and a screenshot worthy layout. Look up current docs online if needed, and make sure it runs locally without extra setup.
