I am not sure if true and false are proper swing modes. What do each mean? Wouldn't it be the case that you have swing_mode with 3 modes off, horizontal and vertical?

I haven't worked with swing modes a lot, so I might be incorrect, but please let me know what you think

[LG-ThinQ-Integration]

Our device provides on(true) and off(false) functions for horizontal and vertical respectively.

[joostlek]

Yes, but aren't those all 3 swing modes rather than having on and off?

[LG-ThinQ-Integration]

The API supports on and off respectively, and according to the developer guide, if the horizontal exists separately, the vertical is instructed to be separated. Do you suggest combining the two into one and implementing it with just swing_mode?

knx's swing_mode example

        if self._device.swing.initialized:
            self._attr_supported_features |= ClimateEntityFeature.SWING_MODE
            self._attr_swing_modes = [SWING_ON, SWING_OFF]

        if self._device.horizontal_swing.initialized:
            self._attr_supported_features |= ClimateEntityFeature.SWING_HORIZONTAL_MODE
            self._attr_swing_horizontal_modes = [SWING_ON, SWING_OFF]
