required_features for some entity services #141868Description
The problem
For the evohome integration, if you invoke water_heater.set_temperature, you'll get an NotImplementedError:
2025-03-30 21:13:13.254 ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [140543346768720] Error handling message: Unknown error (unknown_error) David Bonnes from 127.0.0.1 (Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/134.0.0.0 Safari/537.36)
Traceback (most recent call last):
...
File "/home/dbonnes/clients/hass/homeassistant/components/water_heater/__init__.py", line 314, in set_temperature
raise NotImplementedError
NotImplementedError
... instead of:
Entity water_heater.domestic_hot_water does not support action
water_heater.water_heater.set_temperature
This is despite evohome clearly setting _attr_supported_features thus:
self._attr_supported_features = (
WaterHeaterEntityFeature.AWAY_MODE
| WaterHeaterEntityFeature.OPERATION_MODE
)This issue applies for these three services:
SERVICE_SET_AWAY_MODESERVICE_SET_TEMPERATURESERVICE_SET_OPERATION_MODE
For example, in water_heater\__init__.py, we have:
component.async_register_entity_service(
SERVICE_SET_OPERATION_MODE,
SET_OPERATION_MODE_SCHEMA,
"async_handle_set_operation_mode",
)... where is should (?) be:
component.async_register_entity_service(
SERVICE_SET_OPERATION_MODE,
SET_OPERATION_MODE_SCHEMA,
"async_handle_set_operation_mode",
[WaterHeaterEntityFeature.OPERATION_MODE], # <-- missing
