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

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

Removing Channels

Open Channel List node Delete line or comment out with # at start Save changes

Changing Check Frequency

Open Hourly Check node Modify interval 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: Open Filter New Videos node Find: if (videoUrl && !videoUrl.includes('/shorts/')) 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.
