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_caseta integration in Home Assistant is responsible for communicating with the Lutron Caseta Smart Bridge for the Caseta product line of dimmers, switches, shades, and sensors. It will also communicate with the Lutron Radio RA2 Main Repeater for the RA2 Select product line of dimmers, switches, shades, and sensors.
This integration only supports the Caseta line of products. The Smart Bridge (L-BDG2-WH), Smart Bridge PRO (L-BDGPRO2-WH), and RA2 Select (RR-SEL-REP2-BL) models are supported. For the RadioRA 2 and HomeWorks QS product lines, see the Lutron component.
The currently supported Caseta and RA2 Select devices are:
- Wall and plug-in dimmers as lights
- Wall switches as switches
- Scenes as scenes
- Lutron shades as covers
- Lutron smart fan speed control
- Lutron Occupancy/Vacancy sensors
When configured, the
lutron_caseta integration will automatically discover the currently supported devices as setup in the Lutron Smart Bridge. 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 ‘Lamp’ in a room called ‘Bedroom’ becomes
light.bedroom_lamp in Home Assistant.
To use Lutron Caseta devices in your installation, you must first log in to your Lutron account and generate a certificate that allows Home Assistant to connect to your bridge. This can be accomplished by downloading and executing get_lutron_cert.py, which will generate three files: caseta.key, caseta.crt, caseta-bridge.crt when you run it. See the instructions at the top of the script for more information.
Once you have the three necessary files, place them in your configuration directory and add the following to your
# Example configuration.yaml entry lutron_caseta: - host: IP_ADDRESS keyfile: caseta.key certfile: caseta.crt ca_certs: caseta-bridge.crt
Note that multiple hubs can be specified by using multiple configuration blocks, but each of them requires its own
ca_certs to be generated and specified.
The certificate chain that Home Assistant will use to authenticate to the bridge.
It is recommended to assign a static IP address to your Lutron Smart Bridge. This ensures that it won’t change IP address, so you won’t have to change the
host if it reboots and comes up with a different IP address.
Use a DHCP reservation on your router to reserve the address or in the PRO model of the Smart Bridge, set the IP address under Network Settings in the Advanced / Integration menu in the mobile app.
To get Lutron Caseta roller, honeycomb shades, lights, scene and switch working with Home Assistant. First follow the instructions for the general Lutron Caseta integration above.
After setup, shades will appear in Home Assistant using an
entity_id based on the name used in the Lutron mobile app. For example, a shade called ‘Living Room Window’ will appear in Home Assistant as
For more information on working with shades in Home Assistant, see the Covers component.
position ranges from
0 for fully closed to
100 for fully open.
After setup, dimmable lights including wall and plug-in dimmers will appear in Home Assistant using an
entity_id based on the name used in the Lutron mobile app. For example, a light called ‘Bedroom Lamp’ will appear in Home Assistant as
For non-dimmable lights or switched loads, see the switch section on this page.

The Lutron Caseta scene platform allows you to control your Smart Bridge Scenes that are created in the Lutron mobile app.
After setup, scenes will appear in Home Assistant using an
entity_id based on the name used in the Lutron mobile app. For example, a scene called ‘Entertain’ will appear in Home Assistant as
For more information on working with scenes in Home Assistant, see the Scenes component.
After setup, switches will appear in Home Assistant using an
entity_id based on the name used in the Lutron mobile app. For example, a light switch called ‘Master Bathroom Vanity’ will appear in Home Assistant as
For dimmable lights including wall and plug-in dimmers, see the light section on this page.
For more information on working with switches in Home Assistant, see the Switches component.
After setup, fans will appear in Home Assistant using an
entity_id based on the name used in the Lutron mobile app. For example, a light switch called ‘Master Bedroom Ceiling Fan’ will appear in Home Assistant as
For more information on working with fans in Home Assistant, see the Fans component.
Occupancy sensors can be added to a Lutron Caseta system to trigger events when an area becomes vacant and, optionally, occupied. However, Lutron systems report occupancy and vacancy statuses only in occupancy groups – that is, groups of one or more sensors.
Occupancy groups will appear in Home Assistant using an
entity_id based on the area name in which the first sensor of the group is located. For example, one or more sensors in the Master Bathroom will appear in Home Assistant as
An occupancy group is considered occupied if any of the sensors in the group are currently in an “occupied” state. Specifically, this means that motion has been detected more recently than that sensor’s particular timeout setting. Only after all sensors in an occupancy group report being vacant does the occupancy group itself report being vacant.
Lutron Caseta occupancy sensors support 4 different timeouts and 3 different sensitivity levels, but those are only controllable from the devices themselves and cannot be set from either Home Assistant or even the Caseta mobile app.
Because Lutron Caseta devices automatically report state to Home Assistant (rather than relying on polling), occupancy status updates occur almost instantaneously.
