React智能家居能源监控仪表盘

I’m building a frontend-only Smart Home Energy Monitoring Dashboard using React, Tailwind CSS, and ShadCN UI, styled in a GitHub-dark theme. The interface displays real-time metrics like temperature, voltage, power, and load in responsive cards, includes smart ON/OFF control, a simulated barcode scanner to register devices, and shows AI-generated energy-saving suggestions and alerts. I want to expand it by adding live barcode scanning via webcam, energy usage charts (using Recharts), a scheduling UI for automation, and an AI chatbot panel for usage tips. The goal is to make the dashboard fully interactive, responsive, and ready to integrate with future backend or IoT data.
