Possible breaking change for this integration in core 2024.12.0.

Upgraded to core 2024.12.0 and since then, the integration crash with the following :

AttributeError: 'SinopeThermostat' object has no attribute '__attr_swing_horizontal_modes'. Did you mean: '_attr_swing_horizontal_modes'?

This seems to be due to a new fonctionality who requires all climate integration to declare the new attribute "_attr_swing_horizontal_modes". Opened a HA core ticket about this because if my interpretation is right, it could break all climate integration who don't declare this attribute.

I think it could also be solved if you declare this attribute on your side.

Don't flame me if I am wrong, I am new to HA and only trying to help.

Oh! Pis salut de Québec, je viens de voir ta bio.

[omelettedufromagee]

Salut! I have the same issue, this comes from this change in HA core:
home-assistant/core@a7db35c

[sbeaudoin]

Even though the problem impact possibly every climate implementation, HA consider it out of their responsability and they closed the ticket 🙄😠.

[omelettedufromagee]

I rolled back the core version. I think HA messed up, they might have a change to remove the supported_features warning. So it could be resolved in upcoming update.

[sbeaudoin]

Maybe I will make a pull request, but in the meantime, here are the steps to resolve it manually :

1. If not already installed, install Visual Studio Code in HA (VSCode - The tool name is "Studio Code Server")
2. In VSCode, go to the /config/custom_components/sinope/climate.py file.
3. At about line 399, make sure to add the two lines begining with "_attr_swing".

class SinopeThermostat(ClimateEntity):
    """Implementation of a Sinope thermostat."""

    _enable_turn_on_off_backwards_compatibility = False
    _attr_temperature_unit = UnitOfTemperature.CELSIUS
    _attr_swing_horizontal_modes = []
    _attr_swing_horizontal_mode = ""

4. Save the file (Ctrl-S) and restart HA.

Sorry I was busy on my other custom_component neviweb130 with a major code change.
I forgot to add the patch for swing_horizontal.
I'll add the changes and make a release

Do you have version 1.7.1. swing mode should be fixed in that one.
