Custom Component implements device state attributes.

G'day,

I know you are migrating to official support as a native component, but I've just seen this message in the logs against the custom component, so figured I would raise an issue regardless:

Entity climate.backyard_spa_climate (<class 'custom_components.balboa.climate.BalboaSpaClimate'>) implements device_state_attributes. Please report it to the custom component author.
