RSS Function

Using RSS in SenseCraft HMI

Introduction

The RSS function in SenseCraft HMI allows you to transform your screen-based devices into real-time information displays. By connecting to RSS feeds from news outlets, blogs, weather services, and more, you can create dynamic displays that automatically update with the latest content. This feature is perfect for creating news tickers, information boards, or personal dashboards that keep you informed without manual intervention.

This tutorial will guide you through understanding RSS feeds and using the RSS function in SenseCraft HMI to display content on your device.

This article will use the reTerminal E1002 as an example to explain how to use this feature on the SenseCraft HMI platform.

Understanding RSS

What is RSS?

RSS (Really Simple Syndication) is a standardized web feed format used to publish frequently updated content such as:

• News articles
• Blog posts
• Podcasts
• Video updates
• Weather forecasts
• Stock market data

RSS feeds allow users to stay updated without having to visit each website individually. Instead, new content is automatically delivered to your RSS reader or, in this case, your SenseCraft HMI-enabled device.

How RSS Works

1. Content publishers (websites, blogs, news outlets) create RSS feeds that contain their latest content in a standardized XML format
   
2. Feed readers (like the RSS function in SenseCraft HMI) regularly check these feeds for updates
   
3. When new content is published, the feed reader retrieves and displays the updates

Benefits of Using RSS

• Real-time updates: Get the latest information without manual refreshing
• Content aggregation: Combine multiple sources in one display
• Filtered information: Only receive the content you’re interested in
• Bandwidth efficient: RSS feeds contain only essential content, not full web pages
• No advertisements: RSS typically delivers clean content without ads

Getting Started

Accessing the RSS Function

Step 1. Navigate to the SenseCraft HMI platform below.

Understand the RSS Interface

The RSS interface consists of two main sections:

2. Display Area: The main section where RSS content will be displayed after configuration
   

Configurate RSS Feeds

Add an RSS Feed

Step 1. Locate the RSS Configuration panel on the top of the screen, Find the RSS URL input field
Step 2. Enter a valid RSS feed URL in the field (e.g., https://news.google.com/rss)
Step 3. Click the Set button to validate and apply the RSS feed, If the URL is valid, the system will begin fetching and displaying content from the feed

Display Set and Customization

Once your RSS feed is configured, you can adjust how content is displayed: Step 1. Use the same interval and dither mode settings found in the Gallery function:

• Interval(min): Sets how frequently the display refreshes with new content
• Dither Mode: Choose between “Full Color” or “Black and White” based on your display type

Step 2. Click Save to store your configuration
Step 3. Click Preview to see how the RSS content will display on your device
Step 4. Click Deploy to send the configuration to your connected device

How to Find RSS Feeds for Websites

Many websites offer RSS feeds, but they’re not always easy to find. Here are some methods to locate RSS feeds:

• Method 1: Look for RSS Icons
  Many websites display an RSS icon (usually orange) or links labeled “RSS,” “Feed,” or “Subscribe” in their footer or sidebar.

• Method 2: Add “/feed” to Blog URLs
  For many WordPress-based sites, adding “/feed” to the end of the URL often works:
  

  https://example.com/feed

• Method 3: Use Browser Extensions
  Browser extensions like “RSS Feed Reader” for Chrome or “Awesome RSS” for Firefox can detect available feeds on websites you visit.

  

• Method 4: Check Source Code
  

  1. Visit the website
  2. Right-click and select “View Page Source”
  3. Search (Ctrl+F) for “rss” or “feed”
  4. Look for links with “application/rss+xml” in the type attribute

• Method 5: Use RSS Feed Finders
  Services like:
  

  • Feed Finder
    
  • RSS.app
    These can help discover RSS feeds for websites that don’t advertise them prominently.

Advanced RSS Display Tips

Optimizing RSS Content for Your Display

For the best experience with RSS feeds on your SenseCraft HMI device:

1. Choose feeds with appropriate content length:

   • Feeds with short titles and descriptions work best for small displays
   • Full-article feeds may be too text-heavy for e-paper displays

2. Consider update frequency:

   • Match your interval setting to the feed’s update frequency
   • News feeds may update hourly, while blog feeds might update daily

3. Test different dither modes:

   • “Black and White” mode works best for text-heavy RSS feeds on e-paper displays
   • “Full Color” is better for feeds with images on LCD displays

4. Be mindful of image content:

   • Some RSS feeds include images that may not display well on all devices
   • Feeds with large images may load slower

Troubleshooting

Common RSS Issues and Solutions

1. “Invalid RSS Feed” Error:

   • Verify the URL is correct and includes the http:// or https:// prefix
   • Check if the feed is accessible by pasting the URL in a browser
   • Some feeds may require authentication or have access restrictions

2. Feed Loads but No Content Appears:

   • The feed may be empty or not currently publishing content
   • The feed format might not be compatible (try an alternative feed)
   • Try a different, more active feed

3. Content Appears Garbled or Incorrectly Formatted:

   • Try a different dither mode
   • The feed might contain special characters or formatting that isn’t supported
   • Consider using a feed filtering service to clean up the content

4. Feed Stops Updating:

   • The source website may have changed their feed URL
   • There might be temporary server issues
   • Try removing and re-adding the feed

5. Deployment Fails:

   • Ensure your device is properly connected to SenseCraft HMI
   • Check your device’s internet connection
   • Restart your device and try deploying again

Conclusion

The RSS function in SenseCraft HMI provides a powerful way to turn your screen-based devices into dynamic information displays. By connecting to RSS feeds, you can create automatically updating displays for news, weather, technical updates, or any other content available via RSS.

Remember that the quality of your RSS display depends largely on the feeds you choose. Experiment with different feeds, update intervals, and display settings to create the perfect information display for your needs.
