Automated Monitoring and Alerting for Critical Data

This n8n workflow provides a robust solution for real-time monitoring of your critical data stored in PostgreSQL. It's designed to automatically scan your database at regular intervals for specific conditions, such as values exceeding a threshold of 70. Upon detection, it triggers an immediate SMS notification via Twilio, informing you about the specific sensor and its reading. To prevent repeated alerts for the same event, the workflow also updates the database, marking the notification as sent. This ensures efficient data oversight and timely intervention for any anomalies.
