Automate weather reports with GPT-4 Mini and Open-Meteo API to Gmail and Slack

This workflow provides a comprehensive weather reporting system with two main functionalities: a scheduled daily summary and an interactive AI agent for dynamic queries.

Who's it for?

This template is ideal for anyone who wants to stay updated on the weather, from individuals planning their day to teams needing automated daily briefings. It's also a great example for developers and n8n users who want to explore the capabilities of AI Agents and integrating external APIs in their workflows.

What it does / How it works

This workflow operates in two distinct modes:

1. Scheduled Daily Summary: The workflow triggers automatically every day at 9:00 AM (customizable) or can be run manually. It fetches the latest weather data for a specified location (default is near Chiba, Japan) from the Open-Meteo API. It then formats a message with the day's maximum and minimum temperatures. Finally, it sends this summary to a designated Gmail address and a Slack channel.

2. AI-Powered Forecasts via Chat: When you send a message to the Chat Trigger webhook, it activates the AI Agent. The AI Agent, powered by an OpenAI model, understands natural language questions like "What's the humidity right now?" or "Will it be warmer tomorrow?". The agent uses an HTTP Request tool to fetch real-time, specific data from the weather API to answer your question. The generated answer is then sent back to you via both Gmail and Slack.
