energy-tracker-api 1.1.0

Async Python client for Energy Tracker API

Energy Tracker API Client

Python client for the Energy Tracker public REST API.

Installation

pip install energy-tracker-api

Requirements

• Python 3.10+
• Personal Access Token from Energy Tracker
• Async/await support (asyncio)

Usage

import asyncio
from energy_tracker_api import EnergyTrackerClient, CreateMeterReadingDto
from datetime import datetime

async def main():
    client = EnergyTrackerClient(access_token="your-token")

    meter_reading = CreateMeterReadingDto(
        value=123.45,
        timestamp=datetime.now(),     # Optional - server uses current time if omitted
        note="Manual reading"         # Optional
    )

    await client.meter_readings.create(
        device_id="your-device-id",
        meter_reading=meter_reading,
        allow_rounding=True           # Optional
    )

    await client.close()

asyncio.run(main())

Async Context Manager

import asyncio
from energy_tracker_api import EnergyTrackerClient, CreateMeterReadingDto

async def main():
    async with EnergyTrackerClient(access_token="your-token") as client:
        reading = CreateMeterReadingDto(value=456.78)
        await client.meter_readings.create("your-device-id", reading)

asyncio.run(main())

Configuration

client = EnergyTrackerClient(
    access_token="your-token",
    base_url="https://custom-api.example.com",  # Optional
    timeout=30                                  # Optional, default: 10 seconds
)

Error Handling

from energy_tracker_api import (
    EnergyTrackerAPIError,
    ValidationError,
    AuthenticationError,
    ForbiddenError,
    ResourceNotFoundError,
    ConflictError,
    RateLimitError
)

try:
    await client.meter_readings.create(device_id, meter_reading)
except ValidationError as e:
    print(f"Validation error: {e}")
    print(f"Details: {e.api_message}")
except AuthenticationError:
    print("Authentication failed - check access token")
except ForbiddenError:
    print("Insufficient permissions")
except ResourceNotFoundError:
    print("No valid meter for timestamp")
except ConflictError:
    print("Meter reading already exists for timestamp")
except RateLimitError as e:
    print(f"Rate limit exceeded")
    if e.retry_after:
        print(f"Retry after {e.retry_after} seconds")
except EnergyTrackerAPIError as e:
    print(f"API error: {e}")
