Automated Cold Weather Alerts with SIGNL4 and OpenWeatherMap
detail.loadingPreview
Never miss a cold snap again. This workflow automatically monitors weather conditions using OpenWeatherMap and sends immediate alerts to SIGNL4 when temperatures drop below a set threshold. Ideal for teams needing proactive temperature monitoring.
About This Workflow
This n8n workflow provides a robust solution for automated temperature monitoring and alert dissemination. It leverages the OpenWeatherMap node to fetch real-time weather data for a specified city, such as Berlin. An 'If' node then critically evaluates the current temperature, triggering an action only if it falls below 25°C. Upon this condition being met, the SIGNL4 node is invoked to send a detailed alert, including the exact temperature and location coordinates, directly to your SIGNL4 channel. This ensures that relevant personnel are immediately notified of critical weather changes, enabling swift action and operational continuity.
Key Features
- Automated Weather Monitoring: Regularly fetches real-time temperature data for any city.
- Customizable Alert Thresholds: Easily set your desired temperature limit for triggering alerts.
- Direct SIGNL4 Integration: Sends critical alerts directly to your SIGNL4 app with rich details.
- Location-Aware Alerts: Includes latitude and longitude in alerts for precise context.
- Scheduled or Manual Triggering: Can be set to run automatically on a schedule or manually tested.
How To Use
- Connect OpenWeatherMap: Add the 'OpenWeatherMap' node and enter your API key. Specify the
cityName(e.g., 'Berlin'). - Configure Temperature Check: Add an 'If' node. Set the
leftValueto={{ $json.main.temp }}and theoperatorto 'less than' (lt), with arightValueof25. - Set up SIGNL4 Alerts: Add the 'SIGNL4' node. Configure the
messageto include dynamic temperature data like{{ $json.main.temp }} °C. Define thetitleandexternalId. PopulatelocationFieldsValues.latitudewith={{ $json.coord.lat }}andlocationFieldsValues.longitudewith={{ $json.coord.lon }}. - Choose Trigger: Select either the 'Schedule Trigger' node to set a recurring check time (e.g., daily at 6:15 AM) or the 'When clicking ‘Test workflow’' node for manual testing.
- Establish Connections: Link the output of your chosen trigger to the 'OpenWeatherMap' node, then 'OpenWeatherMap' to the 'If' node, and finally the 'If' node's output (for when the condition is met) to the 'SIGNL4' node.
