Lutron


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.

Configuration

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, add the following to your configuration.yaml file using the IP address of your RadioRA 2 main repeater:

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

Configuration Variables

host

(string)(Required)

The IP address of the Main Repeater.

username

(string)(Required)

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

password

(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.

Keypad buttons

Individual buttons on keypads are not represented as entities. Instead, they fire events called lutron_event whose payloads include id and action attributes.

The id attribute includes the name of the keypad and the name of the button, normalized the same way entity names are. For example, if the keypad is called “Kitchen Keypad” and the button is called “Dinner” the event’s id will be kitchen_keypad_dinner.

The action attribute varies depending on the button type.

For raise/lower buttons (dimmer buttons, shade controls, etc.) there will be two values, pressed and released, fired when the button is pressed and when it’s released, respectively.

For single-action buttons (scene selection, etc.), action will be single, and there will only be one event fired. This is a limitation of the Lutron controller which doesn’t give Home Assistant any way of knowing when a single-action button is released.

Scene

This integration uses keypad programming to identify scenes. Currently, it only works with SeeTouch 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.
