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.
