qnap-client 1.0.2

Async Python client for QNAP NAS — replaces python-qnapstats

QNAP NAS Integration for Home Assistant

Async Python client for QNAP NAS. Replaces the unmaintained python-qnapstats with a fully async, aiohttp-based library with typed models, proper exception handling, Container Station support, and graceful handling of unexpected API responses.

Why This Exists

python-qnapstats hasn't had a meaningful update in years. Fan sensor support and external drive support were added to the source repo but never published to PyPI. The library is synchronous, has no typed return values, and crashes on certain NAS models due to missing key handling.

This library fixes all of that.

Installation

pip install qnap-client

Quick Start

import asyncio
from qnap_client import QnapClient

async def main():
    async with QnapClient("192.168.1.100", 8080, "admin", "password") as client:
        data = await client.get_all()
        print(f"NAS: {data.system_info.name} ({data.system_info.model})")
        print(f"CPU: {data.system_info.cpu_usage_percent:.1f}%")
        print(f"Health: {data.system_health.status}")
        for vol in data.volumes:
            used_pct = vol.used_bytes / vol.total_bytes * 100
            print(f"Volume {vol.name}: {used_pct:.1f}% used")
        if data.firmware_update.latest_version:
            print(f"Firmware update available: {data.firmware_update.latest_version}")

asyncio.run(main())
