:description: Instructions for setting up Home Assistant sensors with ESPHome that import states from your Home Assistant instance.
:image: home-assistant.svg
2019-01-06 18:56:14 +01:00
The ``homeassistant`` sensor platform allows you to create sensors that import
states from your Home Assistant instance using the :doc:`native API </components/api>`.
2019-01-06 18:56:14 +01:00
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: homeassistant
name: "Temperature Sensor From Home Assistant"
entity_id: sensor.temperature_sensor
2022-11-14 14:17:55 +01:00
Entity state attributes can also be imported:
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: homeassistant
id: current_temperature
entity_id: climate.living_room
attribute: current_temperature
2019-01-06 18:56:14 +01:00
.. note::
This component is only for numeral states. If you want to import arbitrary text states
from Home Assistant, use the :doc:`Home Assistant Text Sensor </components/text_sensor/homeassistant>`.

Although you might not plan to *export* states from the node and you do not need an entity of the node
in Home Assistant, this component still requires you to register the node under Home Assistant. See:
:doc:`Getting started with Home Assistant </guides/getting_started_hassio>`

Configuration variables:
------------------------
- **name** (**Required**, string): The name of the sensor.
- **entity_id** (**Required**, string): The entity ID to import from Home Assistant.
- **attribute** (*Optional*, string): The name of the state attribute to import from the
specified entity. The entity state is used when this option is omitted.
2019-02-07 18:07:16 +01:00
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
2019-02-17 12:28:17 +01:00
- All other options from :ref:`Sensor <config-sensor>`.

2022-11-14 14:17:55 +01:00
.. note::
The sensors implemented by this component are by default ``internal``, to avoid exporting them back to
2022-11-14 14:17:55 +01:00
Home Assistant. Should you still want to do that (eg. because you use ESPHome's very efficient filters
on them) you need to specifically configure ``internal: false``. Also, ``state_class``, ``unit_of_measurement``
2022-11-14 14:17:55 +01:00
are not inherited from the imported sensor so you need to set them manually.
