Components add support for devices, automation, and much much more to Home Assistant. The following things are supported out-of-the-box.

## {% linkable_title Entities %}

Entities are things that you want to observe within Home Assistant. Support for these things are provided by the entity components [Light](/components/light.html), [Switch](/components/switch.html), [Thermostat](/components/thermostat.html), [Media player](/components/media_player.html), [Device tracker](/components/device_tracker.html), and [Sun](/components/sun.html).


<p class='note'>
Support for these services is provided by the Home Assistant community and not the service providers.
