Initial Check
The action is not performed (even once) If expected_state and/or validation are set and passing. For example, light.turn_on with expected_state set to on won't be performed if the entity's state is already on.
This is the new default behavior. The integration's configuration dialog can be used to disable the initial check (globally) and cause actions to get performed at least once (the previous behavior of the integration).
