Description
Overview
This weather update automation workflow delivers daily temperature notifications for Berlin, leveraging a scheduled orchestration pipeline. Designed for users requiring consistent morning weather insights, it triggers every day at 9 AM via a Cron node to fetch current atmospheric data and dispatch alerts automatically.
Key Benefits
- Automates daily weather retrieval and notification without manual input or oversight.
- Utilizes a time-based trigger ensuring precise, repeatable delivery at 9:00 AM daily.
- Integrates OpenWeatherMap API for accurate, real-time temperature data specific to Berlin.
- Employs Gotify service for secure, direct push notifications to subscribed devices or apps.
Product Overview
This automation workflow begins with a Cron node configured to trigger exactly once a day at 9:00 AM, initiating the data orchestration pipeline. Upon activation, it calls the OpenWeatherMap node to retrieve current weather metrics for Berlin, including temperature and atmospheric conditions, using authenticated API access. The workflow then formats a notification message embedding the temperature value extracted from the JSON response. Using Gotify credentials, the message is sent securely to a Gotify server, enabling real-time push notifications. The synchronous execution flow ensures that the notification is dispatched immediately after data retrieval. Error handling defaults to platform standard behavior, with no explicit retry or backoff policies implemented. All data processing occurs transiently during runtime without persistent storage, maintaining compliance with data minimization principles.
Features and Outcomes
Core Automation
This orchestration pipeline starts with a scheduled Cron trigger, initiating a data fetch from a weather API and culminating in a notification push. The workflow processes the temperature reading deterministically, embedding it into a formatted message for delivery.
- Single-pass evaluation from trigger to notification delivery each day.
- Deterministic data extraction from nested JSON structures (main.temp).
- Execution occurs in a synchronous, linear flow without branching complexity.
Integrations and Intake
The workflow integrates OpenWeatherMap for weather data retrieval and Gotify as the notification delivery platform. Both APIs require credential-based authentication to ensure authorized access. The intake consists of a time-triggered event with no external payload inputs.
- OpenWeatherMap node authenticates via API key for weather data access.
- Gotify node uses stored API credentials for secure notification transmission.
- Cron node triggers event without inbound data, operating on schedule only.
Outputs and Consumption
The output is a text notification sent asynchronously to the Gotify server, containing the current temperature formatted as a string. This message includes a title and dynamic content fields populated from the weather API response.
- Notification message includes temperature in degrees Celsius embedded in text.
- Message payload delivered to Gotify notification endpoint securely.
- Output format is plain text within a JSON-based API call to Gotify.
Workflow — End-to-End Execution
Step 1: Trigger
The workflow initiates with a Cron node scheduled to run daily at 9:00 AM. This time-based trigger requires no external input and acts as the deterministic start event for the entire pipeline.
Step 2: Processing
The OpenWeatherMap node receives the trigger event and queries the current weather for Berlin using authenticated API credentials. The response payload is parsed to extract key metrics, specifically the temperature field within the main object. Basic presence checks ensure the temperature value exists before proceeding.
Step 3: Analysis
Temperature data is directly utilized without further computation or thresholding. The workflow constructs a notification message string dynamically by embedding the extracted temperature value, enabling simple event-driven analysis for message content generation.
Step 4: Delivery
The Gotify node sends the composed notification message and title to a configured Gotify server using stored API credentials. This asynchronous delivery ensures the user receives the daily weather update promptly after data retrieval.
Use Cases
Scenario 1
A user requires automatic daily temperature alerts for planning outdoor activities. This workflow solves that by retrieving weather data at 9 AM and delivering a notification with the current temperature in Berlin. The result is a consistent, hands-free update available every morning.
Scenario 2
An operations team needs timely weather information to adjust logistics scheduling. Using this automation workflow, they receive standardized temperature notifications each day via Gotify, enabling deterministic decision-making based on up-to-date environmental data.
Scenario 3
A developer wants to integrate real-time weather alerts into a self-hosted notification system. This workflow provides a no-code integration pipeline that fetches weather data and forwards formatted messages seamlessly, reducing manual monitoring overhead.
How to use
Import this workflow into your n8n environment and configure the OpenWeatherMap and Gotify credentials with valid API keys. The Cron node is preset to trigger at 9:00 AM daily but can be adjusted as needed. Once activated, the workflow runs autonomously, fetching Berlin’s current temperature and sending notifications via Gotify. Users can expect daily push messages containing the exact temperature reading, ensuring consistent updates delivered without manual intervention.
