Weather Temperature Alert Notification Workflow
This workflow automatically monitors the real-time weather in specified cities, regularly retrieving temperature data to determine if it falls below 25°C. Once the condition is met, the system instantly pushes a low-temperature alert via SIGNL4, including detailed temperature and geographical location information. This process effectively enhances the response speed of low-temperature warnings, helping businesses, organizations, and individuals take timely measures against cold weather, ensuring the safety of equipment and personal arrangements.

Workflow Name
Weather Temperature Alert Notification Workflow
Key Features and Highlights
This workflow periodically retrieves real-time weather data for a specified city (e.g., Berlin) and automatically evaluates whether the current temperature falls below a preset threshold (25°C). Once the condition is met, it immediately sends an alert notification via SIGNL4, including detailed temperature information and geographic coordinates, enabling precise and timely weather warnings.
Core Problems Addressed
Effectively monitors temperature changes in critical cities, automatically filters and pushes low-temperature alerts to prevent potential risks caused by unnoticed abnormal temperature drops, thereby enhancing emergency response speed and accuracy.
Application Scenarios
- Enterprises or organizations needing to monitor temperature variations in specific cities to prepare in advance for cold and freezing conditions.
- Operations teams leveraging temperature alerts to ensure the safety of equipment or outdoor facilities.
- Individuals or community weather enthusiasts receiving real-time low-temperature reminders to plan travel and daily activities accordingly.
Main Workflow Steps
- Trigger Activation: Supports manual test triggering as well as scheduled automatic triggering (daily at 6:15 AM).
- Calls OpenWeatherMap API to fetch the latest weather data for the specified city.
- Condition node checks if the current temperature is below 25°C.
- If the condition is met, invokes the SIGNL4 service to send an alert notification containing temperature and geographic location details.
Involved Systems or Services
- OpenWeatherMap: API for obtaining real-time weather data.
- SIGNL4: Secure and reliable alert notification platform for instant alerts.
- n8n Scheduling Trigger: Supports both scheduled and manual workflow execution.
Target Users and Value
- Enterprise operations personnel and meteorological service providers requiring real-time city temperature monitoring.
- Business teams relying on weather data for operational and safety decision-making.
- Technical teams and individual users seeking to automate weather alert processes and reduce manual monitoring efforts.
This workflow enables users to achieve automated and intelligent management of low-temperature alerts, ensuring timely responses to weather changes and improving safety and operational efficiency.
