Daily Personalized Weather Forecast Bot for Telegram - n8n Workflow

Markdown formatted string.

This comprehensive n8n workflow provides a solution for users who need timely, detailed, and personalized weather information delivered directly to their preferred messaging platform. Instead of relying on standard, often cluttered weather apps, this automation uses an advanced Code n8n node to process raw OpenWeatherMap API data, generating custom daily overviews, temperature ranges, humidity assessments, and actionable recommendations (like 'Bring an umbrella'). This specialized n8n template is triggered daily, ensuring you receive the forecast before starting your day. By leveraging the power of n8n, this system turns raw data into highly useful, formatted reports, demonstrating the flexibility and customization available within an n8n automation framework.

This automation begins with the Schedule n8n trigger, configured to fire daily at 7:50 AM.

1. Trigger: The Daily Morning n8n trigger initiates the execution flow at the specified time (7:50 AM, local time relevant to the n8n environment).


2. Data Fetching: The OpenWeather API Request n8n node then executes an HTTP GET request to the OpenWeatherMap 5-day forecast endpoint. This specific call requests data for Strassen, Luxembourg (customizable location) using metric units. The n8n node is configured with robust error handling, including three retry attempts.


3. Smart Processing: The workflow moves to the highly customized Weather Data Processor n8n node (a Code node). This node contains extensive JavaScript logic to:

1. Delivery: Finally, the Send Weather Update Telegram n8n node receives the HTML message output. It uses the configured Telegram credentials and Chat ID to instantly send the richly formatted forecast to the target group or private chat. This completes the daily execution of the n8n workflow.
