Meshtastic MQTT Parser

A lightweight Python library for parsing Meshtastic MQTT messages into JSON format. This tool makes it easy to build applications that interact with Meshtastic mesh networks via MQTT.

Overview

This library connects to a Meshtastic MQTT broker and decodes various message types into JSON format, making it simple to process Meshtastic mesh network data in your Python applications.

Features

• Connects to any Meshtastic MQTT broker
• Decrypts encrypted messages
• Parses all standard Meshtastic message types
• Outputs clean JSON format
• Message type filtering support
• Simple command-line interface

Installation

pip install cryptography protobuf meshtastic paho-mqtt

usage

python meshtastic_mqtt.py [options]
