multiweatherapi 0.0.25
Python bindings to multiple weather station vendor APIs
Requires Python: >=3.6

# Multi Weather API

Consistent Python bindings for select commercial weather station APIs, such as [Zentra Cloud](https://zentracloud.com/) REST API v3, created for [MSU EnviroWeather Project](https://michiganstate.sharepoint.com/sites/MSUITADSDataScience/Shared%20Documents/Forms/AllItems.aspx?id=%2Fsites%2FMSUITADSDataScience%2FShared%20Documents%2FClients%2FEnviroWeather&viewid=554d191e%2Def24%2D4e36%2Dbc88%2D12660f0e0f8d).

### Background

This is inspired by python bindings for v1 of the Zentra API from the Montana Climate office : MSU Agricultural Weather Office


The EnviroWeather system from the MSU Agricultural Weather Office will interface with weather stations (select list of vendors) deployed and owned privately. Since each vendor has a differrent REST/Web API to access station's weather data, this package aims to provide a consistent interface to all of those stations in order to make it easy for incoporating them into a data pipeline.

### Installation

The Multi-Weather API is currently available on [PyPI](https://pypi.org/project/multiweatherapi/). Install using `pip`:
```bash
pip install multiweatherapi
```

### Usage

```python
>>> from multiweatherapi import multiweatherapi
>>> param = {'sn': 'STATION_ID',
...          'apikey': 'API_KEY',
...          'apisec': 'API_SECRET'}
>>> resp = multiweatherapi.get_reading('davis', **param)
>>> resp.resp_raw # raw JSON response of the reading
>>> resp.resp_parsed # parsed JSON response into list of dict for EnviroWeather project
```

### Requirements

- [Requests](https://docs.python-requests.org/en/latest/)
- [pytz](https://pythonhosted.org/pytz/)
- [pytest](https://docs.pytest.org/en/7.1.x/)

### Outputs

- API Response (JSON)

  The (raw) API response is formatted in JSON and 0th element illustrates the metadata of the API call and 1st (and onward - Davis stations) element(s) depicts weather station measurements retrieved from the API call.

  ```json
  [
    {
      "vendor": "spectrum",
      "station_id": "50400123",
      "start_datetime": "2022-05-26 12:08:07",
      "end_datetime": "2022-05-26 13:08:07",
      "timezone": "ET",
      "request_time": "2022-05-27 12:08:07",
      "python_binding_version": "0.0.17"
    },
    {
      "EquipmentRecords": [
        {
          "SerialNumber": "50400123",
          "TimeStamp": "2022-05-26T16:10:00",
          "SensorData": [
            {
              "ChannelNumber": 0,
              "PortNumber": "A",
              "SensorNumber": 0,
              "SensorType": "Rainfall",
              "TimeStamp": "2022-05-26T16:10:00",
              "FormattedTimeStamp": "2022-05-26 16:10",
              "Value": "0.00",
              "AccumlatedValue": "0.00",
              "DecimalValue": 0.0,
              "AccumlatedDecimalValue": 0.0,
              "Units": "inches",
              "ValueType": "Average"
            },
            ...
    }
  ]
  ```

- Transformed Response (List of Dict)

  The transformed response is formatted in `list` (array) of Python `dict` object. Each `dict` object consists of that measurements that stakeholders are interested in and the metadata that would be used to facilitate data loading into the backend.

  ```json
  [
    {
      "station_id": "50400123",
      "request_datetime": "2022-05-27 12:08:07",
      "pcpn": 0.0,
      "data_datetime": "2022-05-26 16:10",
      "atemp": 21.0,
      "relh": "92.3"
    },
    ...
  ]
  ```

### Testing the package

If you want to test without installing via PIP, there is a script
`get_sample_data.py`  in the main directory which requires a configuration file named '.env' in the root folder. 

```bash
$ pip install -r requirements.txt
$ python get_sample_data.py rainwise /Users/jhp/Desktop/
```

Please refer to [docs/get_sample_data.md](docs/get_sample_data.md) for detail documentation of `get_sample_data.py` 

see also [docs/Test Suite Doco.py](docs/Test%20Suite%20Doco.md) for more formal tests and how to provide station configuration file
