MQTT to HTTP Bridge

This project provides a Python script to bridge MQTT messages to HTTP requests.

Features

• MQTT Client: Subscribes to a specified MQTT topic and listens for incoming messages.
• HTTP Sender: Sends received MQTT messages as HTTP requests to a specified endpoint.
• Environment Variable Configuration: All configurations are managed via environment variables for easy deployment in containerized environments.
• TLS Support: Supports TLS for secure MQTT connections.
• Logging: Configurable logging levels for debugging and monitoring.

Requirements

• Python 3.x
• paho-mqtt: For MQTT client functionality.
• requests: For sending HTTP requests.

You can install the required packages using pip:

pip install paho-mqtt requests

Configuration

Configuration is done via environment variables. Below are the required environment variables:

• MQTT_USER: Username for MQTT broker authentication.
• MQTT_PASSWORD: Password for MQTT broker authentication.
• MQTT_HOST: The hostname or IP address of the MQTT broker.
• MQTT_PORT: The port on which the MQTT broker is running (default is 8883).
• TLS_BOOL: Whether to use TLS for MQTT connections (true or false).
• SUB_TOPIC: The MQTT topic to subscribe to.
• IOTA_ENDPOINT: The HTTP endpoint to which the data should be sent.
• API_KEY: API key for authenticating with the HTTP endpoint.
• LOG_LEVEL: Logging level (e.g., DEBUG, INFO, ERROR). Default is INFO.

Usage

1. Ensure all required environment variables are set.
2. Run the script:

python main.py

The script will subscribe to the specified MQTT topic, listen for messages, and forward them as HTTP requests to the specified endpoint.

Logging

The script uses Python's built-in logging module. You can adjust the logging level via the LOG_LEVEL environment variable to get more or less output for debugging purposes.

Security Note

When using TLS_BOOL=true, ensure you have the necessary certificates in place for a secure connection to the MQTT broker. The script currently does not specify ca_certs, certfile, or keyfile for TLS connections, so you may need to modify the script if your setup requires these.
