I was looking in my HA logs trying to figure out why my Windmill AC unit isn't working with HA anymore, and I see the following:
Logger: homeassistant.helpers.frame
Source: helpers/frame.py:350
First occurred: 7:55:39 PM (1 occurrence)
Last logged: 7:55:39 PM
Detected that custom integration 'windmillac' sets option flow config_entry explicitly, which is deprecated at custom_components/windmillac/config_flow.py, line 34: self.config_entry = config_entry. This will stop working in Home Assistant 2025.12, please create a bug report at https://github.com/bzellman/HACS-WindmillAC
