Describe the bug

A clear and concise description of what the bug or error is and when it happens.

Fresh venv with python 3.14.2
pip install -e .
Home Assistant 2026.1.1 starts up
DWD integration doesn't.
Turns out simple_dwd_weatherforecast==3.1.7 dependencies seem incompatible.
3.2.2 is out, maybe upgrading it fixes this?

[FL550]

Thanks for the report. I'll have a look into this.

[FL550]

I've added a pull-request to the relevant package: uktrade/stream-unzip#154

[FL550]

I'm on it but I'm still waiting for the approval of my PR. If they do not merge my request, I will publish a clone and release a fix this saturday.

Home Assistant will switch completely to Python 3.14 with version 2026.3

https://rc.home-assistant.io/blog/2026/02/25/release-20263/#running-on-python-314-

The version will be released on March 4.

EDIT: Sorry, just saw that the note already came with #239.
