Real-Time Temperature Alerts via SMS
detail.loadingPreview
Automate critical alerts by receiving real-time temperature data from Kafka and sending immediate SMS notifications when thresholds are breached. This workflow ensures prompt action for any temperature-sensitive situation.
About This Workflow
This n8n workflow provides an automated solution for monitoring environmental conditions. It listens to a specified Kafka topic for incoming messages containing temperature data. Upon receiving data, it checks if the temperature exceeds a predefined threshold. If the temperature is too high, it triggers an SMS alert via Vonage to inform designated personnel. This ensures proactive management of environments where temperature stability is crucial, preventing potential damage or operational disruptions. The 'NoOp' node gracefully handles scenarios where the temperature is within acceptable limits, maintaining workflow continuity.
Key Features
- Real-time Kafka Integration: Seamlessly consume messages from any Kafka topic.
- Configurable Temperature Thresholds: Set custom temperature limits for triggering alerts.
- Instant SMS Notifications: Receive immediate SMS alerts via Vonage for critical temperature changes.
- Conditional Logic: Automatically branch workflows based on temperature readings.
How To Use
- Kafka Trigger: Configure the Kafka Trigger node to connect to your Kafka cluster, specify the
topic_test(or your desired topic), and set thegroupId. EnsurejsonParseMessageis enabled for easy data extraction. - IF Node: Set the condition in the IF node to check the incoming temperature. Use the expression
={{$node["Kafka Trigger"].json["message"]["temp"]}}to access the temperature value and set your desired upper limit (e.g.,50). - Vonage Node: If the temperature is above the threshold, configure the Vonage node to send an SMS. Enter your desired sender name (e.g., 'Vonage APIs') and craft your alert message, dynamically including the temperature value using
={{$node["Kafka Trigger"].json["message"]["temp"]}}. - NoOp Node: This node acts as a placeholder for when the temperature is not above the threshold, allowing the workflow to continue or terminate gracefully.
