quickbars-bridge 0.0.4

Async client for QuickBars TV app

quickbars-bridge

Async client for the QuickBars for Home Assistant app used by the Home Assistant QuickBars integration.

This library wraps all outbound HTTP calls made from Home Assistant to a QuickBars TV device:

• Request a pairing code
• Confirm pairing
• Send Home Assistant URL + long‑lived token
• (Optional) Fetch / apply snapshot via HTTP

It is designed to satisfy Home Assistant Core’s guideline: “All communication to external devices or services must be wrapped in an external Python library hosted on PyPI.”

---

Installation

pip install quickbars-bridge

Import path uses underscore: quickbars_bridge

Supported Python: 3.11+ (matches modern Home Assistant requirements).

Usage

import asyncio
from quickbars_bridge import QuickBarsClient

async def main():
    client = QuickBarsClient(host="192.168.1.50", port=9123, timeout=15.0)

    # 1) Request pairing code
    code_info = await client.get_pair_code()
    print("Pair SID:", code_info.get("sid"))

    # 2) Confirm pairing (values shown are examples)
    confirm = await client.confirm_pair(
        code="123456",
        sid=code_info["sid"],
        ha_instance="192.168.1.10",
        ha_name="Home Assistant",
        ha_url="http://homeassistant.local:8123",
    )
    print("Device ID:", confirm.get("id"))

    # 3) Send HA URL + token to the TV
    result = await client.set_credentials(
        url="http://homeassistant.local:8123",
        token="<LONG_LIVED_TOKEN>"
    )
    print("Creds result:", result)

    # 4) (Optional) Snapshot via HTTP
    snap = await client.get_snapshot()
    await client.post_snapshot(snap)

asyncio.run(main())

All methods raise aiohttp.ClientResponseError for non‑2xx responses and typical network exceptions (asyncio.TimeoutError, aiohttp.ClientConnectorError, etc.). Handle these in your integration tests.
