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 integration 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, dimmers, and seeTouch keypad scenes.


When configured, the lutron integration 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, you’ll need to first create a username/password in your Lutron programming software. Once a telnet username/password has been programmed, you can follow the instructions from the next chapter.


To add the Lutron integration to your Home Assistant instance, use this My button:

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.

If you are using RadioRA2 software version 12 or later, the default lutron user with password integration is not configured by default. To configure a new telnet user, go to Settings > Integration in your project and add a new telnet login. Once configured, use the transfer tab to push your changes to the RadioRA2 main repeater(s).

Keypad buttons

Keypad buttons actions are provided in event entities.

Keypad LEDs

Each full-width button on a Lutron SeeTouch, Hybrid SeeTouch, and Tabletop SeeTouch Keypad has an LED that can be controlled by Home Assistant. A service call of switch.turn_off or switch.turn_on against the appropriate LED entity will control the keypad LED.

Keep in mind that the Lutron system will also control the LED state independent of Home Assistant, according to the programming of the RadioRA2 system. This also means you can query LED states to determine if a certain scene is active, since the LED will have been illuminated by the RadioRA2 repeaters. This includes the “phantom” LEDs of Main Repeater Keypad buttons; even though there is no physical button or LED, the RadioRA2 system tracks the scenes and will “light” the LED that can be queried.

If a button is not programmed to control any lights or other devices in the RadioRA2 system but is given a name in the programming software, it will be available to fire events in Home Assistant. However, since there is no way to have a scene “active” on a button with no devices associated, the Main Repeater will automatically extinguish the keypad LED a few seconds after the button press. If you wish to have Home Assistant light the keypad LED after a button press, you will need to delay your service call to light the LED for several seconds, so it arrives after the Main Repeater has sent the command to turn it off.


This integration uses keypad programming to identify scenes. Currently, it works with seeTouch, hybrid seeTouch, main repeater, homeowner, Pico, and seeTouch RF tabletop keypads. The Lutron scene platform allows you to control scenes programmed into your SeeTouch keypads.

After setup, scenes will appear in Home Assistant using the area, keypad and button name.

Occupancy sensors

Any configured Powr Savr occupancy sensors will be added as occupancy binary sensors. Lutron reports occupancy for an area, rather than reporting individual sensors. Sensitivity and timeouts are controlled on the sensors themselves, not in software.
