Receive Messages from a Topic and Send an SMS
This workflow is capable of receiving and parsing messages from a specified topic in the Kafka message queue in real-time. When the temperature exceeds 50 degrees, it automatically triggers an SMS alert notification. By utilizing the Vonage SMS service, it ensures timely delivery of warning information, enhancing monitoring efficiency and response speed. This is applicable in scenarios such as industrial equipment temperature monitoring and IoT sensor data alerts, addressing the issues of delays and omissions in manual monitoring.

Receive Messages from a Topic and Send an SMS
Key Features and Highlights
This workflow enables real-time reception of messages from a specified Kafka topic (topic_test), automatically parses the message content, and triggers SMS alert notifications based on specific conditions (temperature exceeding 50°C). Leveraging Vonage SMS service, it instantly sends warning messages, achieving an automated process from message reception to alert dispatch.
Core Problem Addressed
It addresses the need for real-time monitoring of critical data (such as temperature) from distributed messaging systems and timely alerting, eliminating delays and risks of omission associated with manual monitoring. This enhances response speed and system intelligence.
Application Scenarios
- Industrial equipment temperature monitoring and alerting
- Real-time alerts for IoT sensor data
- Anomaly notifications for key production line parameters
- Any scenario requiring SMS notifications triggered by Kafka messages
Main Process Steps
- Listen to the specified Kafka topic (topic_test) using the Kafka Trigger node to receive and parse messages in real time.
- Use an IF node to evaluate whether the temperature value in the message exceeds the threshold of 50°C.
- When the temperature exceeds the threshold, trigger the Vonage node to send SMS alert notifications to relevant personnel.
- If the temperature is normal, execute the NoOp node to perform no operation.
Involved Systems or Services
- Kafka: Serves as the message queue, pushing temperature data in real time.
- Vonage: SMS API service used to send alert messages.
- n8n platform nodes: Kafka Trigger, IF condition evaluation, Vonage SMS sending, NoOp placeholder node.
Target Users and Value
Ideal for operations engineers, equipment managers, and IoT solution developers who require real-time monitoring of critical metrics with timely notifications. This automated workflow reduces manual intervention, improves monitoring efficiency and response speed, and ensures that anomalies are detected and addressed promptly.
Monitor USDT ERC-20 Wallet Balance with Etherscan and Telegram Notifications
This workflow is capable of automatically monitoring the balance changes of a specified ERC-20 USDT wallet every 5 minutes. It uses the Etherscan API to obtain the latest balance and compares it with previous records. Once a balance change is detected, the system will immediately send a detailed notification via Telegram, ensuring that users are promptly informed of their fund dynamics. Even if the balance remains unchanged, a corresponding reminder will be sent to enhance information transparency, allowing users to efficiently manage their digital assets and prevent abnormal transactions.
Voice Receptionist for Appointment Management
This workflow automates telephone appointment management, utilizing voice AI technology. Customers can make appointment inquiries, update times, and cancel appointments via phone. The system accesses Google Calendar in real-time to ensure the accuracy of appointment information and synchronizes all data to an Airtable database. Additionally, the preservation of call records and transcribed texts facilitates subsequent analysis, enhancing service quality. The entire process adheres to business hours requirements, helping enterprises achieve efficient and intelligent customer service, significantly improving customer satisfaction.
n8n Instance Startup Notification Workflow
This workflow sends real-time notifications to a designated Mattermost channel when an automation platform instance starts, ensuring that team members are promptly informed about the system status. By automatically monitoring the instance's operation, it prevents interruptions in automated tasks due to system anomalies, thereby enhancing operational efficiency and response speed. It is particularly suitable for technical teams and operations personnel who require continuous and stable operation of automated processes, providing the organization with transparent service status and reducing the risk of service unavailability.
Validate Seatable Webhooks with HMAC SHA256 Authentication
This workflow is designed to securely validate Webhook requests from Seatable, using the HMAC SHA256 signature mechanism to ensure data integrity and authenticity. It listens for POST requests in real-time, calculates the hash value of the request body, and compares it with the signature in the request header to ensure that the request has not been tampered with. Upon successful validation, it returns HTTP 200 to continue processing; if validation fails, it returns HTTP 403, enhancing interface security to prevent malicious requests and ensuring safe and trustworthy data exchange. This is suitable for automated processes that need to handle Seatable event notifications.
VPS Automatic Upgrade Package Detection and Email Notification Workflow
This workflow automatically checks for upgradable packages on the VPS server every day. When it detects packages that need upgrading, it immediately sends a detailed upgrade list in a formatted HTML email to a specified inbox. Through automated monitoring and timely notifications, it helps operations and maintenance personnel quickly understand the security and performance update requirements of the server, preventing security risks and performance issues caused by outdated versions, thereby improving the efficiency and security of server maintenance.
Restore Your Credentials from GitHub
The main function of this workflow is to automatically restore all credentials from the GitHub backup repository, ensuring that users can quickly and securely recover critical configurations. By flexibly configuring the GitHub repository path, this process enables batch retrieval and automatic import of credential files, mitigating the risk of service interruptions caused by credential loss. It simplifies the cumbersome steps of manual recovery and enhances the security and convenience of credential management, making it suitable for multi-environment synchronization and centralized management needs.
Default Error Workflow Configuration
This workflow is designed to automatically update the error handling configurations of all workflows, ensuring that processes without specific error handling logic can uniformly point to the default error handling workflow. By utilizing both scheduled and manual triggering methods, it flexibly and efficiently maintains error management, preventing omissions and confusion. This workflow enhances the system's stability and operational efficiency, ensuring that all workflows can quickly respond and execute standardized error handling processes in the event of an exception, making it suitable for automated environments that require unified error handling standards.
