Automate Weather Data Extraction and Formatting
detail.loadingPreview
Streamline your workflow by automatically fetching current weather data from OpenWeatherMap. This n8n workflow extracts key details like temperature, humidity, wind speed, description, and city name, preparing it for further processing or integration.
About This Workflow
This n8n workflow is designed to efficiently capture and standardize weather information. It begins with a webhook trigger, allowing for external systems to initiate the data retrieval process. Upon activation, the workflow calls the OpenWeatherMap API to fetch real-time weather data for a specified city. The crucial step involves a 'Set' node that meticulously extracts and renames relevant data points: temperature in Celsius (tempC), humidity percentage (humidity), wind speed (windspeed), a textual description of the weather (description), and a combined city and country identifier (city). The keepOnlySet parameter ensures a clean output, focusing solely on the defined variables. This makes the data ready for immediate use in subsequent workflow steps, such as logging, notifications, or further data enrichment.
Key Features
- Automated Weather Data Fetching: Integrates with OpenWeatherMap to get real-time weather information.
- Customizable Trigger: Initiates workflows via a flexible webhook.
- Data Extraction & Renaming: Precisely pulls and labels key weather parameters.
- Clean Output Formatting: Ensures only relevant data is passed on for further processing.
- City and Country Identification: Combines location data for clear context.
How To Use
- Set up the Webhook Node: Configure the 'Webhook' node to receive incoming requests. The
pathshould be set to a unique identifier for your webhook. - Configure OpenWeatherMap Node: In the 'OpenWeatherMap' node, provide the
cityNamedynamically, likely by referencing data received from the webhook trigger (e.g.,={{$json["body"]["city"]}}). Ensure your OpenWeatherMap API key is set up in your n8n credentials. - Define Data Extraction in Set Node: In the 'Set' node, under the 'Values' section, add new string properties for each piece of weather data you want to extract. Use the provided JSON path expressions to reference data from the OpenWeatherMap node (e.g.,
tempC: '={{$json["main"]["temp"]}}'). - Connect the Nodes: Link the 'Webhook' node's main output to the 'OpenWeatherMap' node's main input. Then, link the 'OpenWeatherMap' node's main output to the 'Set' node's main input.
