LLM Device Control with LangChain, LangGraph, LangServe, and Ollama using MQTT

This repository provides tools to control and query the state of devices (lights and doors) in a room using MQTT. These tools are integrated with LangChain, LangGraph, LangServe, and Ollama to facilitate more complex workflows, natural language processing, and distributed task management.

Installation

Ensure that you have the necessary dependencies to run this system.

pip install -qU langgraph langchain-community langchain_ollama "langserve[server]" paho-mqtt

Make sure you have an MQTT broker set up and connected to the devices you want to control or query.
