Database Alerts: Notion Monitoring with SIGNL4 Notifications

This n8n workflow automates industrial machine monitoring by polling a Notion database table that simulates sensor data (e.g., temperature, pressure, or binary up/down status). On a schedule, it checks for 'down' items; if detected, it triggers an alert in SIGNL4, a mobile alerting app for teams, and marks the Notion item to prevent duplicates.

SIGNL4 status updates—like acknowledgments, closures, annotations, or escalations—are captured via a webhook listener, which processes them using custom function logic to update the corresponding Notion record. Alerts auto-close when the machine status returns to 'up' in Notion, ensuring seamless team coordination.

Benefits include real-time notifications reducing downtime response times, automatic synchronization eliminating manual tracking, and scalability for various databases or sensors. Ideal for IT/DevOps monitoring, manufacturing IoT, production lines, or sales pipeline alerts simulating critical events. Easily adapt for SQL/NoSQL DBs or other integrations.
