Public Presentation

Display information screens on TVs, monitors, and digital signage without requiring login.

What is Public Presentation?​

Public Presentation lets you show HMI pages on public displays like lobby TVs, monitoring walls, or kiosks. The pages automatically rotate at intervals you set, perfect for:

  • Building lobby information displays
  • Factory floor monitoring screens
  • Meeting room dashboards
  • Retail digital signage

Getting Started​

Creating Your First Presentation​

  1. Click the menu icon (☰) in the top-left corner
  2. Go to Settings → Public Presentation Settings
  3. Click the Add button
  4. Fill in:
    • Name: Give it a descriptive name (e.g., "Lobby Display")
    • Code: A number that becomes part of the URL (e.g., 14)
    • Interval: How long each page shows before switching (in milliseconds, so 30000 = 30 seconds)
    • Enable Animation: Turn on for smooth transitions between pages
  5. Click Save

Adding Pages to Your Presentation​

  2. Click Add Page

  5. Click Save

Viewing Your Presentation​

  1. Click the Preview button (eye icon) next to your presentation
  2. A new browser tab opens with your presentation running
  3. Copy this URL for your display devices: http://your-server:5000/present/14 (replace 14 with your code)
tip

Set this URL as the homepage on your display device so it starts automatically when powered on.

Adjusting Video Display​

If videos appear cropped or have unwanted black bars, you can adjust how they fit:

Changing Video Fit Mode​

  1. Go to Settings → Video Settings
  2. Find and select the video you want to adjust
  3. Look for the Video Fit dropdown
  4. Choose from:
    • Cover - Fills the entire area, may crop edges (default)
    • Contain - Shows the complete video, may show black bars
    • Fill - Stretches to fit exactly
  5. Click Save

When to use each mode:

  • Use Contain when you need to see the entire video content
  • Use Cover when you want edge-to-edge display and slight cropping is acceptable

Testing Without Live Data​

If you want to test your presentation before connecting to live data systems:

  1. Go to Settings → General Settings
  2. Find Enable Demo Mode and turn it ON
  3. Click Save

Demo Mode shows simulated data that updates automatically, letting you see how your presentation looks and functions.

Common Questions​

How do I change how long each page displays?​

  1. Go to Settings → Public Presentation Settings
  2. Click on your presentation
  3. Change the Interval value (in milliseconds)
    • 15000 = 15 seconds
    • 30000 = 30 seconds
    • 60000 = 1 minute
  4. Click Save

Content Ideas​

Mix different types of content for variety:

  • Banner pages - News, announcements, messages
  • Summary pages - Key metrics and highlights

  • Use charts and gauges to show data visually
  • Test your presentation from where viewers will actually be standing
