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][energiewacht].

## Installation

```bash
pip install omnikinverter
```

## Usage

```python
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

- Signal Quality (only with JS)
- Firmware Version
- IP Address

## Use cases

This python package is used in the following projects, among others:

- [home-assistant-omnik-inverter][omnik-inverter] by Robbin Janssen

## Contributing

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](CONTRIBUTING.md).

Thank you for being involved! :heart_eyes:

## Setting up development environment

The simplest way to begin is by utilizing the [Dev Container][devcontainer]
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][devcontainer-shield]][devcontainer]

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

You need at least:

- Python 3.12+
- [Poetry][poetry-install]

### Installation

Install all packages, including all development requirements:

```bash
poetry install
```

_Poetry creates by default an virtual environment where it installs all
necessary pip packages_.

### Prek

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

```bash
poetry run prek install
```

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

```bash
poetry run prek run --all-files
```

### Testing

It uses [pytest](https://docs.pytest.org/en/stable/) as the test framework. To run the tests:

```bash
poetry run pytest
```

To update the [syrupy](https://github.com/tophat/syrupy) snapshot tests:

```bash
poetry run pytest --snapshot-update
```
