Smart Home Energy Consumption Real-Time Monitor

Build a smart home energy monitor that feels like a precision instrument. A circular gauge with a smooth sweeping needle occupies the center, displaying current draw in watts with exact numerical readout beneath. Below the gauge, three appliance cards sit in a row showing consumption for HVAC, lighting, and always-on devices with crisp icons and color-coded status indicators. The background is midnight blue with electric green accents for active states and amber for alerts. Use realistic consumption numbers with proper units and clear energy flow indicators. Avoid placeholder text, overlapping elements, decorative clutter, and exaggerated visual effects.
