:description: Instructions for setting up homeassistant sensors with esphomelib that import states from your homeassistant instance.
:image: home-assistant.png
The ``homeassistant`` sensor platform allows you to create a sensors that import
states from your Home Assistant instance using the :doc:`native API </esphomeyaml/components/api>`.
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: homeassistant
name: "Temperature Sensor From Home Assistant"
entity_id: sensor.temperature_sensor
.. 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 </esphomeyaml/components/text_sensor/homeassistant>`.
Importing attributes is currently not supported, but you can create template sensors in Home Assistant
that return the attribute of a sensor and then import the template sensor here.
Configuration variables:
------------------------
- **name** (**Required**, string): The name of the sensor.
- **entity_id** (**Required**, string): The entity ID to import from Home Assistant.
- **id** (*Optional*,:ref:`config-id`): Manually specify the ID used for code generation.
- All other options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
