Usage

Please also refer to examples for more detailed usage.

Installation

# Choose the version you want to install
VERSION=0.9.0
pip install frequenz-client-reporting==$VERSION

Initialize the client

from datetime import datetime

from frequenz.client.common.metric import Metric
from frequenz.client.reporting import ReportingApiClient

# Change server address if needed
SERVER_URL = "grpc://reporting.api.frequenz.com:443?ssl=true"
API_KEY = open('api_key.txt').read().strip()
client = ReportingApiClient(server_url=SERVER_URL, key=API_KEY)

Besides the microgrid_id, component_ids, and metrics, start, and end time, you can also set the sampling period for resampling using the resampling_period parameter. For example, to resample data every 15 minutes, use a resampling_period of timedelta(minutes=15).

Query metrics for a single microgrid and component:

data = [
    sample async for sample in
    client.list_single_component_data(
        microgrid_id=1,
        component_id=100,
        metrics=[Metric.AC_ACTIVE_POWER, Metric.AC_REACTIVE_POWER],
        start_dt=datetime.fromisoformat("2024-05-01T00:00:00"),
        end_dt=datetime.fromisoformat("2024-05-02T00:00:00"),
        resampling_period=timedelta(seconds=1),
    )
]

Query metrics for multiple microgrids and components

# Set the microgrid ID and the component IDs that belong to the microgrid
# Multiple microgrids and components can be queried at once
microgrid_id1 = 1
component_ids1 = [100, 101, 102]
microgrid_id2 = 2
component_ids2 = [200, 201, 202]
microgrid_components = [
    (microgrid_id1, component_ids1),
    (microgrid_id2, component_ids2),
]

data = [
    sample async for sample in
    client.list_microgrid_components_data(
        microgrid_components=microgrid_components,
        metrics=[Metric.AC_ACTIVE_POWER, Metric.AC_REACTIVE_POWER],
        start_dt=datetime.fromisoformat("2024-05-01T00:00:00"),
        end_dt=datetime.fromisoformat("2024-05-02T00:00:00"),
        resampling_period=timedelta(seconds=1),
        states=False, # Set to True to include state data
        bounds=False, # Set to True to include metric bounds data
    )
]

Optionally convert the data to a pandas DataFrame

import pandas as pd
df = pd.DataFrame(data)
print(df)

Command line client tool

The package contains a command-line tool that can be used to request data from the reporting API.

reporting-cli \
    --url localhost:4711 \
    --key=$(<api_key.txt)
    --mid 42 \
    --cid 23 \
    --metrics AC_ACTIVE_POWER AC_REACTIVE_POWER \
    --start 2024-05-01T00:00:00 \
    --end 2024-05-02T00:00:00 \
    --format csv \
    --states \
    --bounds

In addition to the default CSV format the data can be output as individual samples or in dict format.
