 OpenClaw's Gateway exposes an **OpenAI-compatible Chat Completions endpoint** (`POST /v1/chat/completions`). This lets you use OpenClaw as a **conversation agent** in Home Assistant's Assist pipeline — enabling voice control, automations, and smart home commands.
 
-#### Prerequisites
+There are two ways to connect it to Home Assistant:
 
-- [HACS](https://hacs.xyz/) installed on your Home Assistant
+---
-- [Extended OpenAI Conversation](https://github.com/jekalmin/extended_openai_conversation) integration
 
-#### Step 1 — Enable the endpoint
+#### Option 1 — OpenClaw Integration (recommended)
+
+The **native OpenClaw integration** provides auto-discovery, a Lovelace chat card, voice mode, tool invocation services, and status sensors — all in one package.
+
+**Step 1 — Enable the endpoint**
 
 In the add-on configuration, set `enable_openai_api`: **true**, then restart.

-#### Step 2 — Install Extended OpenAI Conversation
+**Step 2 — Install the OpenClaw integration**
+
+Via HACS:
+1. In HACS, add as a custom repository:
+   - Repository: `https://github.com/techartdev/OpenClawHomeAssistantIntegration`
+   - Category: **Integration**
+2. Install and restart Home Assistant
+
+Or manually: copy `custom_components/openclaw` from the repo into your HA config directory.
+
+**Step 3 — Add the integration**
+
+1. Go to **Settings → Devices & Services → Add Integration**
+2. Search for **OpenClaw**
+3. If the addon is running locally, it will be **auto-discovered** — just click Submit
+4. If connecting to a remote instance, fill in host, port, token, and SSL settings manually
+
+> **`lan_https` mode**: The integration auto-detects this and connects to the internal gateway port on loopback — no certificate setup needed for local addons.
+
+**Step 4 — Set as conversation agent**
+
+1. Go to **Settings → Voice Assistants**
+2. Edit your assistant (or create a new one)
+3. Under **Conversation agent**, select **OpenClaw**
+
+**Step 5 — Expose entities**
+
+Go to **Settings → Voice Assistants → Expose** and toggle on the entities you want OpenClaw to control.
+
+**Step 6 — Add the chat card (optional)**
+
+The integration auto-registers a Lovelace card. Add it to any dashboard:
+```yaml
+type: custom:openclaw-chat-card
+```
+
+The card includes message history, typing indicator, voice input, wake-word support, and TTS responses.
+
+> **Works with standalone OpenClaw too.** The integration doesn't require the HA addon — it connects to any reachable OpenClaw gateway over HTTP/HTTPS. See the [integration README](https://github.com/techartdev/OpenClawHomeAssistantIntegration) for remote connection details.
