[Lutron](http://www.lutron.com/) is an American lighting control company. They have several lines of home automation devices that manage light switches/dimmers, occupancy sensors, HVAC controls, etc. The `lutron` component in Home Assistant is responsible for communicating with the main hub for these systems.

Presently, there's only support for communicating with the [RadioRA 2](http://www.lutron.com/en-US/Products/Pages/WholeHomeSystems/RadioRA2/Overview.aspx) Main Repeater and only handle light switches and dimmers.

When configured, the `lutron` component will automatically discover the rooms and their associated switches/dimmers as configured by the RadioRA 2 software from Lutron. Each room will be treated as a separate group.

To use Lutron RadioRA 2 devices in your installation, add the following to your configuration.yaml file using the IP of your RadioRA 2 Main Repeater:

``` yaml

lutron:

lutron_host: <ip>

lutron_user: lutron

lutron_password: integration

It is recommended to assign a static IP address to your Main Repeater. This ensures that it won't change IP addresses, so you won't have to change the `lutron_ip` if it reboots and comes up with a different IP address.
