### {% linkable_title Working with dates %}
The `template` sensors are not limited to use attributes from other entities but can also work with [Home Assistant's template extensions](/docs/configuration/templating/#home-assistant-template-extensions). This template contains no entities that will trigger an update, so either we need to use `homeassistant.update_entity` or add an `entity_id:` line for an entity that will force an update - here we're using `sun.sun`.

This example shows how to add `entity_id` to a template to allow tracking of updates. Fixing an error caused in (81.0)

Useful entities to choose might be `sensor.date` which update once per day, or `sensor.time` which updates once per minute.
Note: If a template uses more than one sensor they can be listed
