Automated SMS Alerts for Postgres Outlier Data via Twilio
This workflow queries a Postgres database every minute for outlier readings without notifications, sends SMS alerts via Twilio, and marks them as notified.
This n8n workflow automates database monitoring and alerting by running a Cron trigger every minute to query a Postgres database for records where a value exceeds 70 and no notification has been sent (notification = false). Upon detecting such outliers, it immediately sends an SMS alert via Twilio to a specified phone number, including details like sensor ID and value. Finally, it updates the database record using a Set node to mark the notification as sent (true), preventing duplicate alerts.
