Egauge-Async

asyncio APIs for communicating with eGauge meters.

Examples

Get current rates

import asyncio
from egauge_async import EgaugeClient

async def get_current_rates():
    egauge = EgaugeClient("http://egaugehq.d.egauge.net")
    current_readings = egauge.get_current_rates()
    print(current_readings)

asyncio.run(get_current_rates())

Get weekly changes over the last 4 weeks

import asyncio
from egauge_async import EgaugeClient

async def get_weekly_changes():
    egauge = EgaugeClient("http://egaugehq.d.egauge.net")
    weekly_changes = egauge.get_weekly_changes(num_weeks=4)
    print(weekly_changes)

asyncio.run(get_weekly_changes())

Get available registers

import asyncio
from egauge_async import EgaugeClient

async def get_registers():
    egauge = EgaugeClient("http://egaugehq.d.egauge.net")
    instantaneous_registers = egauge.get_instantaneous_registers()j
    print(instantaneous_registers)
    historical_registers = egauge.get_historical_registers()
    print(historical_registers)

asyncio.run(get_historical_registers())

Implementation Details

This package uses the publically-documented XML API provided by eGauge Systems. It also provides support for the newer JSON API with JWT authentication.

Testing

The project includes both unit tests and integration tests:

Running Tests

# Run all unit tests (default)
uv run pytest

# Run with coverage
uv run pytest --cov=egauge_async

# Run integration tests (requires real eGauge device)
export EGAUGE_HOST="egauge12345.local"
export EGAUGE_USERNAME="owner"
export EGAUGE_PASSWORD="your_password"
uv run pytest -m integration

Integration tests validate functionality against a real eGauge device and are automatically skipped if the required environment variables (EGAUGE_HOST, EGAUGE_USERNAME, EGAUGE_PASSWORD) are not set.
