Heisskleber
🇩🇪Heißkleber m: "hot glue".
Heisskleber is a versatile library designed to seamlessly "glue" together various data producers and consumers across a multitude of protocols including zmq, mqtt, udp, serial, influxdb, and cmdline. With the ambition to extend into REST API interactions and file operations, Heisskleber offers both synchronous and asynchronous interfaces to cater to a wide range of IoT connectivity needs.
Features
- Multiple Protocol Support: Easy integration with zmq, mqtt, udp, serial, and cmdline. Future plans include REST API and file operations.
- Custom Data Handling: Customizable "unpacker" and "packer" functions allow for the translation of any data format (e.g., ascii encoded, comma-separated messages from a serial bus) into dictionaries for easy manipulation and transmission.
- Extensible: Designed for easy extension with additional protocols and data handling functions.
Installation
You can install Heisskleber via pip from PyPI:
$ pip install heisskleber
Quick Start
Here's a simple example to demonstrate how Heisskleber can be used to connect a zmq source to an mqtt sink:
"""
A simple forwarder that takes messages from a serial device and publishes them via MQTT.
"""
import asyncio
from heisskleber.serial import SerialSubscriber, SerialConf
from heisskleber.mqtt import MqttPublisher, MqttConf
async def main():
source = SerialSubscriber(config=SerialConf(port="/dev/ACM0", baudrate=9600))
sink = MqttPublisher(config=MqttConf(host="mqtt.example.com", port=1883, user="", password=""))
while True:
data, metadata = await source.receive()
await sink.send(data, topic="/hotglue/" + metadata.get("topic", "serial"))
asyncio.run(main())
All sources and sinks come with customizable "unpacker" and "packer" functions, making it simple to work with various data formats.
