  • Shorts Exclusion: Automatically excludes YouTube Shorts from notifications
  • Rate Limiting: 30-second delay between notifications to prevent spam
  • Batch Processing: Processes multiple channels sequentially
  • Error Handling: Continues execution even if one channel fails

How to Use

Understanding Workflow Execution

Default Schedule: Hourly

  • Executes every hour
  • Checks all channels
  • Processes videos from last 60 minutes
  • Prevents duplicate notifications

Execution Duration: 1-5 minutes for 10 channels. Rate limiting adds 30 seconds per video.

Adding New Channels

  1. Open Channel List node
  2. Add new URL on new line
  3. Save (Ctrl+S)
  4. Change takes effect on next run

Removing Channels

  1. Open Channel List node
  2. Delete line or comment out with # at start
  3. Save changes

Changing Check Frequency

  1. Open Hourly Check node
  2. Modify interval
  3. If changing from hourly, update Filter New Videos node:
    • Find: cutoffDate.setHours(cutoffDate.getHours() - 1);
    • Change -1 to match interval (-2 for 2 hours, -6 for 6 hours)

Important: Time window should match or exceed check interval.

Understanding Video Sources

RSS Feed (Primary):

  • Official YouTube RSS
  • Fast and reliable
  • 5-15 minute delay for new videos
  • Structured data

HTML Scraping (Fallback):

  • Immediate results
  • Works when RSS unavailable
  • More fragile

Benefits of dual approach:

  • Reliability: If one fails, other works
  • Speed: Scraping catches videos immediately
  • Completeness: RSS ensures nothing missed
  • Videos are deduplicated automatically

Excluding YouTube Shorts

Shorts are filtered by checking URL for /shorts/ path.

To include Shorts:

  1. Open Filter New Videos node
  2. Find: if (videoUrl && !videoUrl.includes('/shorts/'))
  3. Remove the !videoUrl.includes('/shorts/') check

Rate Limiting

30-second wait between notifications:

  • Prevents flooding RocketChat
  • Allows users to read each notification
  • Avoids rate limits

Impact: 5 videos = 2.5 minutes, 10 videos = 5 minutes

To adjust: Open Wait 30 sec node, change amount field (15-60 seconds recommended)

Handling Multiple Channels

Channels processed sequentially:

  • Prevents overwhelming workflow
  • Ensures reliable execution
  • One failed channel doesn't stop others
  • Recommend 20-50 channels per workflow

FAQ

Q: How many channels can I monitor?
A: Recommend 20-50 per workflow. Split into multiple workflows for more.

Q: Why use both RSS and scraping?
A: RSS is reliable but delayed. Scraping is immediate but fragile. Both ensures no videos missed.

Q: Can I exclude specific video types?
A: Yes, add filtering logic in Filter New Videos node. Already excludes Shorts.

Q: Will this get my IP blocked?
A: Unlikely with hourly checks. Don't check more than every 15 minutes.

Q: How do I prevent duplicate notifications?
A: Ensure time window matches schedule interval. Already implemented.

Q: What if channel changes handle?
A: Update URL in Channel List node. YouTube maintains redirects.

Q: Can I monitor playlists?
A: Not directly. Would need modifications for playlist RSS feeds.
