About This Workflow
Overview
This n8n workflow automates the creation of an intelligent chatbot designed to interact with and provide insights from environmental data. The core functionality involves receiving environmental data via a webhook, processing and embedding this data using Langchain's text splitter and OpenAI embeddings, and then storing these embeddings in a Weaviate vector database. Subsequently, users can query this data, with the workflow utilizing a Langchain agent, memory, and a chat model to understand and respond to queries. The final output is logged to a Google Sheet.
This workflow is particularly useful for building custom dashboards and analytical tools where real-time or historical environmental data needs to be easily accessible and queryable through a conversational interface. It solves the problem of extracting meaningful information from raw environmental datasets without requiring extensive coding or complex data visualization tools.
Key Features
- Webhook Integration: Accepts environmental data from external sources.
- AI-Powered Data Processing: Utilizes Langchain's Text Splitter and OpenAI Embeddings for advanced data preparation.
- Vector Database Storage: Stores data embeddings in Weaviate for efficient similarity search.
- Intelligent Querying: Employs a Langchain agent, memory, and chat model to understand and respond to user queries.
- Data Logging: Appends query logs to a Google Sheet for record-keeping and analysis.
How To Use
- Configure Webhook: Set up the
Webhooknode with your desiredpathto receive environmental data. - Set up AI Nodes: Ensure you have
OPENAI_APIandWEAVIATE_APIcredentials configured for theEmbeddings,Insert,Query, andChatnodes. - Configure Weaviate Index: In the
InsertandQuerynodes, set theindexNametoenvironmental_data_dashboard(or your desired index name). - Set up Google Sheets: Configure the
Sheetnode with your Google Sheets credentials and specify theSHEET_IDandLogsheet name to store the query logs. - Deploy and Test: Activate the workflow and send environmental data to your webhook endpoint. Then, interact with the agent through the defined query mechanisms.
