Asynchronous Python client for [Powerfox][poweropti] devices (poweropti's).
## About
A python package with which you can read the data from a [poweropti][poweropti]
device, via your Powerfox account (cloud polling). [Powerfox][powerfox] has various
poweropti devices on the market that you can use with a power, heat and water meter.
## Installation
```bash
pip install powerfox
```
## Poweropti devices
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.
| Device | Type | Supported |
| --------------------- | ----------- | ---------- |
| PA 201901 / PA 201902 | Power meter | Yes |
| PB 202001 | Power meter | Yes |
| WA 201902 | Water meter | Yes |
| Powerfox FLOW | Gas meter | Yes (report) |
| HA 201902 | Heat meter | Yes |
## Datasets
- `Powerfox.all_devices()` lists all devices linked to your account.
- `Powerfox.device(...)` gives the realtime snapshot for a Poweropti device.
- `Powerfox.report(...)` exposes hourly/daily blocks such as FLOW gas consumption.
### Device inventory (`all_devices`)
Use `Powerfox.all_devices()` to fetch the list of Poweropti devices linked to your
account. This endpoint is independent from the realtime `/current` data.
| Field | Type | Description |
| :-------------- | :----------- | :--------------------------------------------- |
| `device_id` | `str` | Unique identifier of the device. |
| `name` | `str` | Friendly name configured in the app. |
| `date_added` | `datetime` | When the device was linked to your account. |
| `main_device` | `bool` | Whether this is the main device in the portal. |
| `bidirectional` | `bool` | True for prosumer/power meters with feed-in. |
| `type` | `DeviceType` | Division value (`device.type.human_readable`). |
### Realtime device data (`device`)
This route powers all non-FLOW devices. The Powerfox FLOW gas meter does not expose a
`/current` payload, so use the report dataset described below.
<details>
<summary>Realtime dataset details (click to expand)</summary>
#### Power meter snapshot
| Field | Type | Unit | Description |
| :------------------------- | :--------- | :--- | :-------------------------------------------- |
| `outdated` | `bool` | - | Data freshness indicator from Powerfox. |
| `timestamp` | `datetime` | - | Timestamp of the snapshot. |
| `power` | `int` | W | Instant power draw. |
| `energy_usage` | `float` | kWh | Grid import since last reset (`None` if zero). |
| `energy_return` | `float` | kWh | Grid export since last reset (`None` if zero). |
| `energy_usage_high_tariff` | `float` | kWh | High tariff import (optional). |
| `energy_usage_low_tariff` | `float` | kWh | Low tariff import (optional). |
#### Water meter snapshot
| Field | Type | Unit | Description |
| :---------- | :--------- | :--- | :------------------------- |
| `outdated` | `bool` | - | Data freshness indicator. |
| `timestamp` | `datetime` | - | Timestamp of the snapshot. |
| `cold_water`| `float` | m³ | Total cold water usage. |
| `warm_water`| `float` | m³ | Total warm water usage. |
#### Heat meter snapshot
| Field | Type | Unit | Description |
| :------------ | :--------- | :--- | :----------------------------------------- |
| `outdated` | `bool` | - | Data freshness indicator. |
| `timestamp` | `datetime` | - | Timestamp of the snapshot. |
| `total_energy`| `int` | kWh | Total consumed energy. |
| `delta_energy`| `int` | kWh | Consumption delta since previous reading. |
| `total_volume`| `float` | m³ | Total volume (heating circuit). |
| `delta_volume`| `float` | m³ | Volume delta since previous reading. |
</details>
### Report data (`report`)
`Powerfox.report(device_id, *, year=None, month=None, day=None)` exposes the
`my/{device_id}/report` endpoint and returns a `DeviceReport` composed of optional
sections. When no filters are provided the last 24 hours are returned. `month` requires
`year`, and `day` requires both `year` and `month`.
<details>
<summary>Report dataset details (click to expand)</summary>
#### FLOW gas meter (`GasReport`)
| Field | Unit | Description |
| :--------------------- | :------------- | :------------------------------------------------------------------------- |
| `sum` / `total_delta` | m³ / impulses | Total gas consumption for the window. |
| `consumption` | m³ | Consumption for the period (identical to `sum`). |
| `consumption_kwh` | kWh | Consumption converted to kWh (requires tariff). |
| `current_consumption` | m³ | Current FLOW reading from the report payload. |
| `avg_delta`, `min`, `max` | m³ | Aggregated hourly min/max/average consumption. |
| `avg_consumption_kwh` etc. | kWh | Same aggregates in kWh. |
| `sum_currency`, `max_currency` | € | Currency values when a tariff is configured. |
| `report_values` | - | List of `ReportValue` entries (hourly blocks). |
#### Power/Heat/Water history (`EnergyReport`)
| Field | Unit | Description |
| :----------- | :---------- | :-------------------------------------------------- |
| `start_time` | `datetime` | Start of the returned time series. |
| `sum` | kWh / m³ | Total consumption for the requested window. |
| `max` | kWh / m³ | Maximum hourly/daily value in the window. |
| `sum_currency` | € | Optional total cost (requires tariff). |
| `report_values` | - | List of `ReportValue` entries (hourly/daily deltas). |
#### ReportValue entries
Each element in `report_values` represents an hourly (or daily) block.
| Field | Unit | Description |
| :-------------------- | :---------- | :----------------------------------------------------------- |
| `timestamp` | `datetime` | Start time of the block (UTC). |
| `delta` / `consumption` | kWh / m³ | Consumption for that block. |
| `delta_ht` / `delta_nt` | kWh | Tariff specific deltas for power meters. |
| `delta_currency` | € | Cost for the block (requires tariff). |
| `total_delta` | impulses/m³ | Aggregate impulse count when provided (FLOW). |
| `current_consumption` | kWh / m³ | Current instantaneous reading if the API includes it. |
| `values_type` | int | Distinguishes consumption (`1`) vs feed-in (`2`). |
</details>
Use `Powerfox.report(device_id, *, year=None, month=None, day=None)` to retrieve the
hourly or daily datasets from the `my/{device_id}/report` endpoint. This method powers
the Powerfox FLOW gas meter support and can also be used for historic consumption or
feed-in data for other devices. The response is parsed into a `DeviceReport`
dataclass, which may contain:
- `gas`: a `GasReport` section with FLOW totals and hourly consumption.
- `consumption`: consumption data for power meters.
- `feed_in`: feed-in data for bidirectional meters.
The `month` parameter requires `year`, and `day` requires both `year` and `month`. When
no parameters are given the API returns the last 24 hours.
### Example
```python
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](./examples/).
### Class Parameters
| Parameter | value Type | Description |
| :-------- | :--------- | :---------- |
| `username` | `str` | The email address of your Powerfox account. |
| `password` | `str` | The password of your Powerfox account. |
## Contributing
This is an active open-source project. We are always open to people who want to

## 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
```
