Asynchronous Python client for the Omnik Inverter.

About

A python package with which you can read the data from your Omnik Inverter. Keep in mind that this repository uses webscraping, this is not a neat way of data processing but due to the lack of a local API this is the only option.

NOTE: In mid-2021, manufacturer Omnik was declared bankrupt. You can find more information about what your alternatives are here.

Installation

pip install omnikinverter

Usage

import asyncio

from omnikinverter import OmnikInverter


async def main():
    """Show example on getting Omnik Inverter data."""
    async with OmnikInverter(
        host="example_host",
        source_type="javascript",
        username="omnik",
        password="inverter",
    ) as client:
        inverter = await client.inverter()
        device = await client.device()
        print(inverter)
        print(device)


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

For the source type you can choose between: javascript (default), json, html and tcp.

Data

You can read the following data with this package:

Inverter

  • Serial Number
  • Inverter Model
  • Firmware Version - Main
  • Firmware Version - Slave
  • Alarm Code
  • Rated Power (W)
  • Current Power Production (W)
  • Day Energy Production (kWh)
  • Total Energy Production (kWh)

On the tcp source type you can also find:

  • Inverter temperature;
  • Voltage and current for the DC input strings (up to 3)
  • Voltage, current, frequency and power for all AC outputs (also up to 3)
  • Total number of runtime hours.

Device

Setting up development environment

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.

Open in Dev Containers

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

You need at least:

Installation

Install all packages, including all development requirements:

poetry install

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

Pre-commit

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

Testing

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
