Replay: Build UI for Sustainable Energy Management Systems.

TL;DR: Replay revolutionizes UI development for sustainable energy management systems by automatically generating working code from video recordings of user interactions, enabling rapid prototyping and efficient development cycles.

The Energy Sector's UI Challenge: From Complex Systems to Intuitive Interfaces#

Sustainable energy management systems are inherently complex. They involve intricate data flows, real-time monitoring, and sophisticated control mechanisms. Developing intuitive and effective user interfaces for these systems is crucial for operators, engineers, and end-users alike. The challenge? Traditional UI development is slow, resource-intensive, and often fails to capture the nuances of real-world user behavior.

Existing screenshot-to-code solutions offer a limited approach, only capturing static visual elements. They miss the crucial context of user interactions and the dynamic nature of energy management processes. This leads to interfaces that are visually similar but functionally inadequate. We need a solution that understands how users interact with the system, not just what they see on the screen.

This is where Replay steps in.

Replay: Behavior-Driven UI Reconstruction for Energy Management#

Replay leverages the power of video analysis and Gemini's AI capabilities to reconstruct working UI from screen recordings. This "behavior-driven reconstruction" approach understands the intent behind user actions, allowing it to generate code that accurately reflects real-world workflows. Forget static screenshots – Replay uses video as the source of truth.

Here's a comparison:

Replay's ability to analyze video and understand user behavior makes it uniquely suited for building UIs for complex systems like those found in the energy sector.

Building a Solar Panel Monitoring Dashboard with Replay: A Step-by-Step Guide#

Let's walk through building a UI for a solar panel monitoring dashboard using Replay. Imagine you have a video recording of an engineer interacting with an existing (perhaps legacy) system. This video captures the key workflows: checking panel status, reviewing historical performance data, and adjusting system settings.

Step 1: Record the User Interaction#

The first step is to capture a video recording of a user interacting with the existing system or a prototype of the desired UI. Ensure the video clearly shows all user actions, including clicks, form inputs, and navigation.

💡 Pro Tip: Use a screen recording tool with high resolution and frame rate to capture the details of the user interaction. Tools like OBS Studio or QuickTime Player are great options.

Step 2: Upload the Video to Replay#

Upload the recorded video to the Replay platform. Replay's AI engine will analyze the video, identifying UI elements, user actions, and the overall flow of the application.

Step 3: Review and Refine the Generated Code#

Replay generates clean, well-structured code based on the video analysis. You can review and refine the generated code to ensure it meets your specific requirements. Replay supports various front-end frameworks, including React, Vue.js, and Angular.

Here's an example of a React component generated by Replay for displaying solar panel data:

typescript
// Generated by Replay
import React, { useState, useEffect } from 'react';

interface PanelData {
  panelId: string;
  voltage: number;
  current: number;
  power: number;
  status: 'online' | 'offline' | 'fault';
}

const SolarPanelDisplay: React.FC = () => {
  const [panelData, setPanelData] = useState<PanelData[]>([
    // Initial data (replace with actual API call)
    { panelId: 'Panel-001', voltage: 24.5, current: 8.2, power: 200.9, status: 'online' },
    { panelId: 'Panel-002', voltage: 24.3, current: 8.1, power: 196.8, status: 'online' },
    { panelId: 'Panel-003', voltage: 23.9, current: 7.9, power: 188.8, status: 'fault' },
  ]);

  useEffect(() => {
    // Simulate fetching data from an API endpoint
    const fetchData = async () => {
      // Replace '/api/solar-data' with your actual API endpoint
      const response = await fetch('/api/solar-data');
      const data = await response.json();
      setPanelData(data);
    };

    fetchData();

    // Update data every 5 seconds (adjust as needed)
    const intervalId = setInterval(fetchData, 5000);

    return () => clearInterval(intervalId); // Cleanup interval on unmount
  }, []);

  return (
    <div>
      <h2>Solar Panel Monitoring</h2>
      <table>
        <thead>
          <tr>
            <th>Panel ID</th>
            <th>Voltage (V)</th>
            <th>Current (A)</th>
            <th>Power (W)</th>
            <th>Status</th>
          </tr>
        </thead>
        <tbody>
          {panelData.map((panel) => (
            <tr key={panel.panelId}>
              <td>{panel.panelId}</td>
              <td>{panel.voltage}</td>
              <td>{panel.current}</td>
              <td>{panel.power}</td>
              <td>{panel.status}</td>
            </tr>
          ))}
        </tbody>
      </table>
    </div>
  );
};

export default SolarPanelDisplay;

This code snippet demonstrates how Replay can generate a React component for displaying solar panel data. The component fetches data from an API endpoint (you'll need to replace

with your actual endpoint) and displays it in a table.

Step 4: Integrate with Supabase (Optional)#

Replay seamlessly integrates with Supabase, allowing you to easily connect your UI to a backend database. This is particularly useful for storing and managing the data generated by your energy management system.

📝 Note: To use Supabase integration, you'll need a Supabase project and API keys.

Step 5: Inject Custom Styles#

Replay allows you to inject custom styles to match your brand and design preferences. You can use CSS, Sass, or any other styling language to customize the look and feel of your UI.

css
/* Custom styles for the solar panel dashboard */
body {
  font-family: sans-serif;
}

h2 {
  color: #007bff;
}

table {
  border-collapse: collapse;
  width: 100%;
}

th, td {
  border: 1px solid #ddd;
  padding: 8px;
  text-align: left;
}

th {
  background-color: #f2f2f2;
}

.online {
  color: green;
}

.offline {
  color: red;
}

.fault {
  color: orange;
}

This CSS snippet provides basic styling for the solar panel dashboard, including font, colors, and table formatting. You can extend this with more advanced styling to create a visually appealing and user-friendly interface.

Step 6: Generate Product Flow Maps#

Replay automatically generates product flow maps based on the video analysis. These maps provide a visual representation of the user's journey through the application, helping you identify potential bottlenecks and areas for improvement.
