Home Assistant Daikin AC Integration

Changes

The official Home Assistant Daikin AC integration is rounding the target temperature to nearest half degree. It's probably doing that to be compatible with some HVAC systems.

def format_target_temperature(target_temperature):
    """Format target temperature to be sent to the Daikin unit, rounding to nearest half degree."""
    return str(round(float(target_temperature) * 2, 0) / 2).rstrip("0").rstrip(".")


class DaikinClimate(ClimateEntity):
    """Representation of a Daikin HVAC."""

    _attr_name = None
    _attr_has_entity_name = True
    _attr_temperature_unit = UnitOfTemperature.CELSIUS
    _attr_hvac_modes = list(HA_STATE_TO_DAIKIN)
    _attr_target_temperature_step = 1

Since my AC accepts half degrees, I made the proper changes.

def format_target_temperature(target_temperature):
    """Format target temperature to be sent to the Daikin unit."""
    return str(target_temperature)


class DaikinClimate(ClimateEntity):
    """Representation of a Daikin HVAC."""

    _attr_name = None
    _attr_has_entity_name = True
    _attr_temperature_unit = UnitOfTemperature.CELSIUS
    _attr_hvac_modes = list(HA_STATE_TO_DAIKIN)
    _attr_target_temperature_step = 0.5
