## {% linkable_title Trigger State Object %}
Knowing how to access the [state object](/docs/configuration/state_object/) of a trigger entity could be one of the more common questions. Here are a few ways for the [`state`](#state), [`numeric_state`](#numeric_state) and [`template`](#template) triggers:
* `trigger.from_state` will return the **previous** [state object](/docs/configuration/state_object/) of the entity.
* `trigger.to_state` will return the **new** [state object](/docs/configuration/state_object/) that triggered trigger.
* `states[trigger.to_state.domain][trigger.to_state.object_id]` will return the **current** [state object](/docs/configuration/state_object/) of the entity.
