Components

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

Entities

Entities are things that you want to observe within Home Assistant. Support for these things are provided by the entity components Light, Switch, Thermostat, Media player, Device tracker, and Sun.

Light and environment

	Philips Hue turns lights on, controls brightness, and color.
	Nest thermostats displays current temperature and control target temperature/away mode.
	Heat Control reads a temperature sensor and control a heater switch.
	WeMo switches controls and reads the usage statistics from Insight switches.
	TEMPer sensors reads the current temperature.
	LimitlessLED controls your LimitlessLED lights.
	Edimax switches controls the state.
	Efergy Engage hubs monitors home energy use.
	DHTxx reads the temperature and humidity.

Devices and protocols

	MySensors integrates MySensors sensors.
	Raspberry PI switch controls and sensor reads the values of GPIOs.
	Insteon controls devices connected with the ISY994 controller.
	X10 controls devices connected with the ISY994 controller.
	Arduino controls digital pins and read from analog pins.
	RFXtrx sensors monitors values from RFXtrx devices.
	MQTT allows sending and recieving MQTT messages, incl. switches and sensors.
	aREST sensors monitors values from aREST enabled devices.

Presence detection

Offers presence detection by looking at connected devices or by scanning the network.

Cameras and various other entities

Camera allows you to see what going in real-time. Other entities report the current state and/or let you control it.

	Hikvision controls the motion detection setting.
	IP camera integrates a generic IP camera or image url.
	SABnzbd clients monitors queue and download speeds.
	System Monitor tracks CPU, memory, and disk usage on the host machine.
	Transmission monitors status/speeds and changes the speed limits.
	Command line issues command line commands.

Support for these devices is provided by the Home Assistant community and not the manufacturers of these devices.

Organization

Hubs

Home Assistant integrates with a variety of third party Home Automation hubs and networks. It allows you to control the connected switches, lights and sensors via Home Assistant. Click on the following logos for setup instructions:
