twist-innovation-api 0.0.4

Python library to talk to the twist-innovation api

Twist Innovation API

Overview

This is the Twist Innovation API – a Python library for interacting with Twist Innovation devices via MQTT.

Installation

You can install this package using pip:

pip install twist-innovation-api

Alternatively, if you have cloned the repository, install it locally:

pip install .

Contributing the Project (without installing in pip)

This repo can be tested with the include main.py. With this main.py, you don't need to install the package. If you just want to install and use, go to Usage

Configuration

Before running the project, you need to create a configuration file named config.yaml in the project root directory. This file should contain your MQTT broker details:

mqtt_broker: "your-mqtt-broker.com"
mqtt_user: "your-username"
mqtt_pass: "your-password"
mqtt_port: 1883  # Default MQTT port

Testing

You can test the package using the included main.py file. Ensure you have a valid config.yaml file set up, then run:

python main.py

Building

To build the package, run the following command:

python -m build

Pushing to PyPi

To push the package to PyPi, run the following command:

twine upload dist/*

Usage

Import the package in your Python scripts:

import asyncio
import yaml
from typing import Callable, Awaitable
import aiomqtt

from twist import TwistAPI, TwistModel

# Load configuration
with open("config.yaml", 'r') as file:
    config = yaml.safe_load(file)

mqtt_broker = config["mqtt_broker"]
mqtt_user = config["mqtt_user"]
mqtt_pass = config["mqtt_pass"]
mqtt_port = config["mqtt_port"]

async def _noop(topic: str, payload: str):
    pass

callback_f :Callable[[str, str], Awaitable[None]]  = _noop


async def on_model_update(model: TwistModel):
    model.print_context()


async def main():
    global callback_f

    async with aiomqtt.Client(
        hostname=mqtt_broker,
        port=mqtt_port,
        username=mqtt_user,
        password=mqtt_pass
    ) as mqtt_client:

        # Async publish method
        async def mqtt_publish(topic: str, payload: str):
            await mqtt_client.publish(topic, payload)

        # Async subscribe method
        async def mqtt_subscribe(topic: str, callback: Callable[[str, str], None]):
            global callback_f
            callback_f = callback

            async def listen():
                await mqtt_client.subscribe(topic)
                async for message in mqtt_client.messages:
                    assert callback_f is not None
                    await callback_f(message.topic.value, message.payload.decode())

            asyncio.create_task(listen())

        # Initialize Twist API with async methods
        twist_api = TwistAPI(8)
        await twist_api.add_mqtt(mqtt_publish, mqtt_subscribe)

        twist_model_list: list[TwistModel] = await twist_api.search_models()

        for model in twist_model_list:
            model.register_update_cb(on_model_update)
            print(f"{type(model)} has Model id: {model.model_id}, Device id: {model.parent_device.twist_id}")
            
        while True:
            await asyncio.sleep(1)


if __name__ == "__main__":
    asyncio.run(main())
