Failed to set preset mode to {preset_mode}.

Error message

Failed to set preset mode to {preset_mode}.

What it means

Raised by Airobot climate's async_set_preset_mode when the sequence of API calls needed to enter/leave a preset (boost mode toggling plus set_mode) raises AirobotError. ServiceValidationError with translation key set_preset_mode_failed names the requested preset_mode.

Solutions

1. Use only the preset modes listed on the entity (check its preset_modes attribute)
2. Ensure the robot is online, then retry
3. Reload the integration if the error repeats, to refresh tokens and cached settings
4. Inspect logs for the chained AirobotError identifying which sub-command failed

attrs = hass.states.get(entity_id).attributes
if preset_mode not in attrs.get("preset_modes", []):
    raise ValueError(f"Unsupported preset {preset_mode}")

def is_valid_preset(preset_mode: str, preset_modes: list[str]) -> bool:
    return preset_mode in preset_modes

from homeassistant.exceptions import ServiceValidationError

try:
    await hass.services.async_call("climate", "set_preset_mode", {...}, blocking=True)
except ServiceValidationError as err:
    _LOGGER.warning("Airobot set_preset_mode rejected: %s", err)

When it happens

Trigger: Calling climate.set_preset_mode with HOME/AWAY/boost presets when any of set_boost_mode(True/False) or set_mode(...) fails — device offline, cloud error, or an unknown preset_mode key mapping.

Common situations: Switching presets while the robot is unreachable, or requesting a preset the integration's _PRESET_MODE_2_MODE mapping does not contain (which would raise KeyError before this, but malformed preset names reach here via the API path).
