Asynchronous Python client for Powerfox devices (poweropti's).

A python package with which you can read the data from a poweropti device, via your Powerfox account (cloud polling). Powerfox has various poweropti devices on the market that you can use with a power, heat and water meter.

pip install powerfox

Not all Poweropti devices are supported currently. Check the list below to see if your device is working with this package. Or help us by testing a device and let us know if it works.

• List of all your Poweropti devices linked to your account.
• Get information from a specific Poweropti device.

import asyncio

from powerfox import Powerfox


async def main() -> None:
    """Show example on using this package."""
    async with Powerfox(
        username="EMAIL_ADDRESS",
        password="PASSWORD",
    ) as client:
        devices = await client.all_devices()
        print(devices)


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

More examples can be found in the examples folder.

This is an active open-source project. We are always open to people who want to use the code or contribute to it.

We've set up a separate document for our contribution guidelines.

Thank you for being involved! 😍

The simplest way to begin is by utilizing the Dev Container feature of Visual Studio Code or by opening a CodeSpace directly on GitHub. By clicking the button below you immediately start a Dev Container in Visual Studio Code.

This Python project relies on Poetry as its dependency manager, providing comprehensive management and control over project dependencies.

You need at least:

• Python 3.11+
• Poetry

Install all packages, including all development requirements:

poetry install

Poetry creates by default an virtual environment where it installs all necessary pip packages.

This repository uses the pre-commit framework, all changes are linted and tested with each commit. To setup the pre-commit check, run:

poetry run pre-commit install

And to run all checks and tests manually, use the following command:

poetry run pre-commit run --all-files

It uses pytest as the test framework. To run the tests:

poetry run pytest

To update the syrupy snapshot tests:

poetry run pytest --snapshot-update
