Lutron 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 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 address of your RadioRA 2 main repeater:

# Example configuration.yaml entry
  host: IP_ADDRESS
  username: lutron
  password: integration

Configuration Variables


(string)(Required)The IP address of the Main Repeater.


(string)(Required)The login name of the user. The user lutron always exists, but other users can be added via RadioRA 2 software.


(string)(Required)The password for the user specified above. integration is the password for the always-present lutron user.

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 host if it reboots and comes up with a different IP address.
