Python: LaMetric Device API Client

]devcontainer

Asynchronous Python client for LaMetric TIME devices.

About

This package allows you to control and monitor an LaMetric TIME device programmatically, directly on your local network. It is mainly created to allow third-party programs to automate the behavior of the LaMetric device.

Installation

pip install demetriek

Usage

"""Asynchronous Python client for LaMetric TIME devices."""

import asyncio

from demetriek import LaMetricDevice
from demetriek.models import (
    Goal,
    GoalData,
    Chart,
    Model,
    Notification,
    NotificationIconType,
    NotificationSound,
    Simple,
    Sound,
)


async def main():
    """Show example on controlling your LaMetric device."""

    # Create a alert notification, with 3 message frames.
    # First frame is a text, the second is a goal, last one
    # shows a chart. Additionally, the Win! notification sound
    # is played.
    notification = Notification(
        icon_type=NotificationIconType.ALERT,
        model=Model(
            frames=[
                Simple(text="Yeah", icon=18815),
                Goal(
                    icon=7956,
                    data=GoalData(
                        current=65,

                Chart(data=[1, 2, 3, 4, 5, 4, 3, 2, 1]),
            ],
            sound=Sound(id=NotificationSound.WIN),
        ),
    )

    async with LaMetricDevice(
        "192.168.1.2",
        api_key="device_api_key",
    ) as lametric:
        # Raise audio volume... so we can hear the notification
        await lametric.audio(volume=100)
        await lametric.notify(notification=notification)

Setting up development environment

The easiest way to start, is by opening a CodeSpace here on GitHub, or by using the Dev Container feature of Visual Studio Code.

This Python project is fully managed using the Poetry dependency manager. But also relies on the use of NodeJS for certain checks during development.

You need at least:

• Python 3.11+
• Poetry
• NodeJS 18+ (including NPM)

To install all packages, including all development requirements:

npm install
poetry install

As this repository uses the pre-commit framework, all changes are linted and tested with each commit. You can run all checks and tests manually, using the following command:

poetry run pre-commit run --all-files

To run just the Python tests:

poetry run pytest
