Lutron Caseta Pro Component for Home Assistant

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.

This is a custom Home Assistant component to support the following models of Lutron bridges / main repeaters:

  • Lutron Caseta Smart Bridge PRO (L-BDGPRO2-WH)
  • Ra2 Select Main Repeater (RR-SEL-REP-BL / RR-SEL-REP2S-BL / RRK-SEL-REP2-BL)

The bridges / main repeaters are supported through their Telnet integration interface which must be enabled for this component to function. The non-PRO model of the Caseta bridge is not supported. No other interfaces to the Smart Bridge or Main Repeater are used by this component.

The currently supported Lutron devices are:

  • Wall and plug-in dimmers as Home Assistant lights
  • Wall and plug-in switches as Home Assistant switches
  • Scenes as Home Assistant scenes
  • Lutron shades as Home Assistant covers
  • Pico remotes as Home Assistant sensors
  • Fan controllers as Home Assistant fans

This component differs from the Lutron Caseta component in that it only works with the PRO model and uses the relatively well-documented (although still not officially supported) Telnet interface and the Lutron Integration Protocol.

The Ra2 Select Main Repeater functions identically to the Caseta PRO model but with support for 100 devices and a different product line of dimmers, switches, fan controls, shades and occupancy sensors that is not compatible with Caseta.

Custom Component Installation

As this is currently a custom component, it must be installed for it to be loaded by Home Assistant.

  1. Create a directory custom_components in your Home Assistant configuration directory ('config' share if using with the Samba add-on or ~/.home-assistant/ for Linux installations).
  2. Copy lutron_caseta_pro from this project including all sub-directories into the directory custom_components.

It should look similar to this after installation:

 ... etc...
  1. Proceed with first time setup.

First Time Setup

  1. Setup the Lutron app and add all your Lutron devices through the app. Enable Telnet Support under settings menu -> Advanced -> Integration. Also enable static IP under Network Settings and write down the IP.
  2. In your Home Assistant installation, install the custom component by copying in the files as noted in the instructions.
  3. In Home Assistant configuration.yaml create a minimal configuration for the custom component (see below) using the IP address you wrote down and start Home Assistant.
  4. Once started and assuming first time setup, open Home Assistant on your mobile device and you should see a notification to Configure Lutron Caseta Smart Bridge PRO on the front-end. Click on Configure and you’ll see a box to paste your Integration Report.
  5. Switch over to the Lutron app, go to settings -> Advanced -> Integration -> Send Integration Report. When prompted, select ‘Copy to clipboard’.
  6. Switch back to Home Assistant front-end and paste in the Integration Report. If your phone does not have copy and paste options, you will need to share it to yourself through email or to another app that supports copy paste.
  7. Once you submit the Integration Report the component should setup all your devices as dimmers and will save the Integration Report to your config directory as a JSON file.
  8. If you have switches, fans or Lutron shades, open the Integration Report in your config directory using a text editor and find their Integration IDs and edit your Home Assistant configuration as described in the instructions below to tell it which devices are switches or shades. Unfortunately, the Integration Report does not contain this information so you need to do this manually if you have switches, fans or shades. Restart Home Assistant if you change the yaml file.

After first-time configuration, the JSON-format Integration Report will be saved to your Home Assistant configuration directory as lutron_caseta_pro_<bridge ip address>.json, where <bridge ip address> is the IP address of the Bridge / Main Repeater. If it cannot find the Integration Report, it will prompt the user to enter it on the frontend.

When configured, the lutron_caseta_pro component will load the Integration Report and setup all the zones as dimmable lights unless configured otherwise (see below).

The name assigned in the Lutron mobile app will be used to form the entity_id used in Home Assistant. e.g. a dimmer called 'Ceiling Light' becomes light.ceiling_light in Home Assistant. If lights or shades are assigned to an area in the Lutron app, the area name will be prepended to the entity_id. e.g. for area 'Dining Room', it would be light.dining_room_ceiling_light

Minimal Configuration

As a minimum, to use Lutron Caseta devices in your installation, add the following to your configuration.yaml file using the IP of your Smart Bridge:

# Example of minimum configuration.yaml entry
      - host: IP_ADDRESS
        mac: MAC_ADDRESS


  • IP_ADDRESS is the IP address of your Bridge / Main Repeater (e.g.

  • MAC_ADDRESS is the MAC address from the sticker on the bottom of your Smart Bridge / Main Repeater (e.g. a0:f6:fd:12:34:56).

Configuration variables:

  • bridges (Required): Must be a list of smart bridges. Even if you only have one bridge, use - host to start the list.
  • host (Required): The IP address of the Lutron Smart Bridge / Main Repeater.
  • mac (Optional): The MAC address of the Lutron Smart Bridge / Main Repeater. This is a unique string that is used to enable the Entity Registry feature of Home Assistant. It is optional, but strongly encouraged for your configuration to allow for renaming entities IDs and other customization features in the front-end.


Additional configuration is provided:

# Example configuration.yaml entry with device types
      - host:
        mac: a0:f6:fd:12:34:56
        default_transition_seconds: 1.0
        # Note: Configure only switches, shades, and fans, all others will be dimmers
        switch: [ 4, 5 ]
        cover: [ 11, 12 ]
        fan: [ 15 ]

Configuration variables:

  • default_transition_seconds (Optional): Optional number of seconds to apply to every light transition (both on and off). Only affects dimmable lights and value is in seconds.
  • switch (Optional): Array of integration IDs ("ID" in the "Zones" section of Integration Report)
  • cover (Optional): Array of integration IDs ("ID" in the "Zones" section of Integration Report)
  • fan (Optional): Array of integration IDs ("ID" in the "Zones" section of Integration Report)

In the above example Zone 4 and 5 are configured as switches (e.g. switch.<device name> in Home Assistant), Zones 11 and 12 are shades (e.g. cover.<device name> in Home Assistant), and Zone 15 is a fan (e.g. fan.<device name>). If a listed ID is not found in the Integration Report, it will be ignored.

Fan Support

When marking a device as a fan, the component is configured to have four speeds that can be set with a percentage through the turn_on service. The fan speeds are mapped to a percentage as follows:

  • 0 -> Off
  • 25 -> Low
  • 50 -> Medium
  • 75 -> Medium High
  • 100 -> High

The default if calling turn_on without a percentage is 50% or Medium speed.


The Integration Report must be updated after any change to device configuration such as pairing new devices or scene renaming. For scenes, only adding or removing a scene or changing a scene's name will modify the Integration Report and changing light or shade levels will not affect it.

To update the Integration Report, delete the JSON Integration Report from your Home Assistant configuration directory, restart Home Assistant and follow the procedure above for first time setup.

To update the custom component, copy the latest files into custom_components directory and overwrite existing files. If you have no other custom components, you can remove the contents of the directory before copying the files.

Automatic Updates with HACS (Optional)

For easy updates whenever a new version is released, use the Home Assistant Community Store to install the custom component.

HACS will download and install the custom component for you and keep track of updates.

Once HACS is setup, go to Settings -> Custom Repositories and add the following Repository:


And use type Integration. Once installed, add your settings to configuration.yaml as described above.

Pico Remote Sensors

All Pico remotes in the system will each get their own sensor in Home Assistant.

The sensor's value will change when a button is pressed according to this button map.

Example Automation for a Pico Button

- alias: Media Pico Button 1
  id: '1522884919017'
  - alias: Turn on Watch TV
    service: remote.turn_on
      activity: '29535421'
      entity_id: remote.living_room_harmony
  condition: []
  - platform: state
    entity_id: sensor.media_pico
    to: '1'


Enable debugging in your main configuration.yaml to see more logging:

  default: info
    custom_components: debug

If connection errors are evident, try connecting to the IP listed in the configuration using a Telnet client such as PuTTY. A connection refused or timeout error indicates the wrong IP address has been used or the Telnet Support has not been enabled in the mobile app under Settings -> Advanced -> Integration.
