Quickstart: async client with email/password auth.

import asyncio import os from myPyllant import myPyllant, MyPyllantAuthSystem async def main(): auth = MyPyllantAuthSystem( email=os.environ.get("VAILLANT_EMAIL", ""), password=os.environ.get("VAILLANT_PASSWORD", ""), ) async with myPyllant(auth) as client: systems = await client.get_systems() print(systems) asyncio.run(main())

Debug

Known issues

breakingFrom version 0.8.0, the library is fully async. Synchronous usage is no longer supported.

fix

Use async/await with aiohttp. Do not attempt synchronous calls.

affects: >=0.8.0

deprecatedThe legacy 'Authentication' class was removed in 0.9.0. Use 'MyPyllantAuthSystem' instead.

fix

Replace 'from myPyllant import Authentication' with 'from myPyllant import MyPyllantAuthSystem'.

affects: >=0.9.0

gotchaThe API may require a valid Vaillant account. Creating a new account might not work due to SMS verification requirements.

fix

Ensure you have an existing myVAILLANT app account with confirmed email and phone.

affects: all
