Does Lutron Caseta work offline with Home Assistant?

Yes! Once the certificates are set up and the integration is configured, Lutron Caseta works completely offline with Home Assistant. The connection between Home Assistant and the Caseta Bridge is local, no internet required. Even if your internet goes down, your automations will continue to work.

Do I need the Pro bridge or regular bridge for Home Assistant?

Both work, but the Bridge PRO is strongly recommended if you want to use Pico remotes as automation triggers in Home Assistant. The standard Smart Bridge supports lights, dimmers, shades, and fans, but Pico remote button events are only available with the PRO bridge. The extra $50 is worth it for most users.

Is Lutron Caseta worth it for Home Assistant?

Absolutely. Lutron Caseta is one of the most reliable smart lighting systems available. It uses Clear Connect RF technology (not WiFi or Zigbee), which means zero interference and rock-solid reliability. The integration with Home Assistant is fully local, and Pico remotes are incredibly useful for triggering any automation. The higher price compared to other brands is justified by the quality.

What happens if Lutron discontinues support for the bridge?

Your Home Assistant integration would continue working since it uses local control via certificates. You wouldn't be able to use the Lutron app or get firmware updates, but Home Assistant would still control your devices. Lutron has a strong track record of long-term support, and the Caseta line remains their flagship consumer product.

Can I use Lutron with both the Lutron app and Home Assistant?

Yes! Unlike some integrations, Lutron Caseta works simultaneously with the official Lutron app and Home Assistant. Changes made in either place sync automatically. You can continue using the Lutron app for initial setup, firmware updates, and as a backup control method.

Lutron Caseta + Home Assistant Guide

1. Prerequisites

Before starting, ensure you have:

Home Assistant installed and running
Lutron Caseta Smart Bridge (standard or PRO)
Caseta devices already set up and working in the Lutron app
Static IP assigned to your bridge (recommended)
SSH access to your Home Assistant instance (for certificate generation)

Important: Lutron Caseta requires certificate-based authentication. This is more complex than most integrations but provides secure, reliable local control.

2. Smart Bridge vs Bridge PRO

Lutron offers two main bridge options. Your choice affects what features work in Home Assistant.

Feature	Smart Bridge (L-BDG2-WH)	Bridge PRO (L-BDGPRO2-WH)
Lights & Dimmers	Yes	Yes
Shades	Yes	Yes
Fans	Yes	Yes
Scenes	Yes	Yes
Pico remotes in HA	No	Yes
Occupancy sensors in HA	No	Yes
Device limit	75 devices	75 devices
Price	~$80	~$130

Our recommendation: If you plan to use Pico remotes as automation triggers (the main reason people love Caseta with Home Assistant), get the Bridge PRO. It's worth the extra $50.

3. Certificate Generation

Unlike most integrations, Lutron Caseta requires you to generate authentication certificates. This is a one-time process.

Option A: Using the Add-on (Easiest)

If you're running Home Assistant OS or Supervised:

Go to Settings → Add-ons → Add-on Store
Search for "Lutron Certificate"
Install and start the add-on
Open the add-on's web UI
Follow the prompts to authenticate with your Lutron account
The add-on will generate and save the certificates automatically

Option B: Manual Generation

If you can't use the add-on (Home Assistant Container, Core), you'll need to generate certificates manually:

Clone or download the pylutron-caseta repository
Run the certificate generation script
Authenticate with your Lutron account when prompted
Copy the three generated files to your Home Assistant config directory:
- caseta.key
- caseta.crt
- caseta-bridge.crt

Keep these files safe: The certificate files authenticate your Home Assistant instance to the bridge. If you lose them, you'll need to regenerate.

4. Adding the Integration

Step 1: Set a Static IP

Before adding the integration, assign a static IP to your Lutron bridge through your router's DHCP settings. This prevents connection issues if the IP changes.

Step 2: Auto-Discovery or Manual Add

Home Assistant may auto-discover your Caseta bridge. Check Settings → Devices & Services for a "Discovered" entry.

If not discovered:

Go to Settings → Devices & Services
Click + Add Integration
Search for Lutron Caseta
Enter your bridge's IP address
Select or upload your certificate files

Step 3: Verify Devices

After setup, all devices from your Lutron app should appear in Home Assistant. Entity IDs are based on device names in the Lutron app (e.g., "Bedroom Lamp" becomes light.bedroom_lamp).

5. Available Features

Lighting

Dimmers: Full brightness control with transitions
Switches: On/off control
Plug-in dimmers: Same as wall dimmers

Window Treatments

Roller shades: Position control (0-100%)
Honeycomb shades: Position control
Wood blinds: Position and tilt control

Climate

Fan controllers: Speed control (off, low, medium, medium-high, high)

Scenes

Scenes created in the Lutron app are imported as scene entities. Activate them via automations or the UI.

Smart Away

A switch entity is created to toggle Lutron's Smart Away feature on/off.

6. Using Pico Remotes (PRO Bridge Only)

Pico remotes are the killer feature for Home Assistant users. These battery-powered remotes can trigger any automation, not just Lutron lights.

How It Works

With the Bridge PRO, each Pico remote button appears as an event entity in Home Assistant. You can create automations that trigger when buttons are pressed.

Example Automation

automation:
  - alias: "Pico - Toggle Living Room Lights"
    trigger:
      - platform: device
        device_id: [your_pico_device_id]
        domain: lutron_caseta
        type: press
        subtype: "on"
    action:
      - service: light.toggle
        target:
          entity_id: light.living_room

Button Types

on / off: Top and bottom buttons
raise / lower: Middle up/down buttons
stop: Center button (on 5-button Picos)

Pro tip: Pico remotes don't need to be paired to any Lutron device to work with Home Assistant. Buy standalone Picos and use them purely as automation triggers.

7. Troubleshooting

Integration Says "Already Configured"

If you add a new device and try to re-add the integration:

New devices are automatically discovered - just wait a few minutes
Try reloading the integration from Settings → Integrations → Lutron Caseta → ⋮ → Reload

Connection Lost After Router Reboot

Verify the bridge still has the same IP address
Set up a DHCP reservation for the bridge
Restart the integration after the bridge reconnects

Pico Remotes Not Showing

Verify you have the Bridge PRO, not the standard bridge
Ensure the Pico is paired in the Lutron app
Reload the integration

Certificates Invalid

Regenerate certificates using the add-on or manual process
Ensure all three files are present: caseta.key, caseta.crt, caseta-bridge.crt
