Installation

HACS (recommended)

Open HACS → Integrations → + Explore & Download Repositories
Search for OpenClaw and install
Restart Home Assistant
Go to Settings → Devices & Services → Add Integration → OpenClaw

Manual

Prerequisites

The OpenClaw Assistant addon must be installed and running.
The integration will auto-detect it — no manual configuration needed.

Exposed entities (important)

OpenClaw uses Home Assistant's native Assist entity exposure controls. Only entities exposed to Assist are included in the context sent to OpenClaw.

Configure this in Home Assistant:

Go to Settings → Voice assistants
Open the Expose tab
Select which entities are exposed to Assist

Advanced options

Open Settings → Devices & Services → OpenClaw → Configure to tune:

Include exposed entities context
Max context characters
Context overflow strategy (truncate or clear)
Enable tool calls (execute HA services from model tool-call responses)
Require wake word
Wake word text (for example: hey openclaw)
Always-on voice mode (continuous listening while the card is open)
