📡 ISS Position Polling Workflow with Static Data
This workflow demonstrates how to use static data in n8n to implement a polling system that detects changes in the position of the International Space Station (ISS). It ensures that only new or updated data is processed.

🔧 Nodes in Use
🕒 Cron Node
Triggers the workflow every minute.

You can modify the interval to suit your needs.

🌐 HTTP Request Node
Sends a request to an API that returns the current ISS position.

Replace the API endpoint if you'd like to track a different source.

🛠 Set Node
Extracts and passes along only the necessary fields:

timestamp

latitude

longitude

You can configure this to include additional fields if required.

🧠 Function Node
Compares the current API response to the static data stored from the last execution.

If the data has changed, the node returns the updated data and stores it as static data.

If no change is detected, it returns a message: "No New Items".

➕ Possible Extensions
Send updates to Slack, Mattermost, or via email

Store the updated data in:

Airtable

Google Sheets

Any database (PostgreSQL, MySQL, etc.)

Trigger alerts or visualizations based on movement patterns

✅ Benefits of Using Static Data
Efficiently avoids redundant processing

Helps track meaningful changes over time

Ideal for polling APIs where only new data matters
