weishaupt-webif-api 0.1.0

Async Python library for the Weishaupt WebIF heat pump interface.

Weishaupt WebIF API

A Python library for interacting asynchronously with the Weishaupt heating system web interface (WebIF). This library allows you to programmatically retrieve telemetry data and system statistics.

Features

• Asynchronous Design: Built on httpx and asyncio for non-blocking I/O.
• Selective Updates: Fetch only the categories you need (e.g., "Statistik", "Heizkreis") to minimize load on the device's MCU.
• Persistence: Automatically manages session cookies and internal state (cooldowns, request timing) across restarts using local storage.
• Smart Batching: Includes logic to batch requests safely, preventing resource exhaustion on the hardware interface.
• Robust Error Handling: Detects session expiration, login redirections, and MCU resource errors.
• Mock Mode: Access real-world sample data without polling the device—perfect for developing Home Assistant integrations.
• CLI Monitor: A built-in command-line tool to monitor your heat pump telemetry in real-time.

Installation

Currently, this library can be installed locally:

pip install .

Quick Start

import asyncio
from weishaupt_webif_api import WebifConnection

async def main():
    # Initialize the connection
    async with WebifConnection(
        ip="10.10.1.225", 
        username="user", 
        password="pass",
        storage_path="./data"
    ) as api:
        # Fetch specific categories
        data = await api.update_all(["Statistik", "Heizkreis"])

        # Fetch mockup data for developement puposes. This is no real data and wont change!
        mcok_data = await api.update_all_mock(["Statistik", "Heizkreis"])
        
        for category, values in data.items():
            print(f"--- {category} ---")
            for key, value in values.items():
                print(f"{key}: {value}")

if __name__ == "__main__":
    asyncio.run(main())

Configuration & State

The library creates several files in the storage_path to maintain state:

• lwp_cookies.txt: Stores session cookies to avoid redundant logins.
• lwp_state.json: Stores internal metadata, such as request cooldown timers.
• weishaupt_webif_api.log: Contains diagnostic logs for troubleshooting.

These files are excluded from version control by default via .gitignore.

Development

Running Tests

The project uses pytest with pytest-asyncio and respx for mocking API responses.

pytest

Tests utilize HTML fixtures located in tests/fixtures/ to simulate real device responses without requiring access to physical hardware.
