Problems with custom integration Warema WMS Control after update 2025.1

Third party integrations
1

After updating to 2025.1 I unfortunately have a problem with the custom integration for my WAREMA blinds.

Despite updating I haven’t changed anything but the entities are no logger working.

‘Check configuration’ is showing me the following:

Configuration warnings
Platform error 'cover' from integration 'warema_wms_webcontrol' - cannot import name 'DEVICE_CLASS_SHADE' from 'homeassistant.components.cover' (/usr/src/homeassistant/homeassistant/components/cover/__init__.py)

And I have the following log entry:

Logger: homeassistant.config
Source: config.py:1055
First occurred: January 7, 2025 at 14:43:54 (1 occurrences)
Last logged: January 7, 2025 at 14:43:54

I appreciate any help as it sucks to not be able to use the blinds via HA anymore. Updating to 2025.1.1 didn’t help.

Hello RodgerDodger,

That looks like something the Custom Integrator would need to fix.

Did you see if there is an issue open there or open one if it isn’t kn their GitHub?

I have created error with 2025.1: cannot import name 'DEVICE_CLASS_SHADE' · Issue #3 · cornim/ha-warema-integration · GitHub but I am not really hopeful that anything will come of it, judging from the activity on the repository.

Thank you, buddy, as pretty busy right now it’s very welcome.

Have you tried to readd the code files?

Fixed it with ChatGPT!

Will write more in afternoon/evening.

:tada: Works again!

Okay, I have thrown the full code of the /config/custom_components/warema_wms_webcontrol/cover.py into ChatGPT and got this as the result with the prompt “repair this code” (in German).

    CoverEntity, CoverDeviceClass, CoverEntityFeature, ATTR_POSITION, PLATFORM_SCHEMA)

        self.force_update_until = datetime.now()
        self.update_interval = update_interval

    def update(self, force=False):

        else:

I backed up my system and copied the ChatGPT code into /config/custom_components/warema_wms_webcontrol/cover.py, saved, checked the code via Developer Tools (with no error left) and restarted HA.

My 4 enttites - as I have for shades - were recreated as ‘_2’ and after deleting the old ones and renaming the new ones I’m good to go and everything works just like before!
