# P4: homeai-agent — AI Agent, Skills & Automation

> Phase 3 | Depends on: P1 (HA), P2 (Ollama), P3 (Wyoming/TTS), P5 (character JSON)

---

## Goal

OpenClaw running as the primary AI agent: receives voice/text input, loads character persona, calls tools (skills), manages memory (mem0), dispatches responses (TTS, HA actions, VTube expressions). n8n handles scheduled/automated workflows.

---

## Architecture

```
Voice input (text from P3 Wyoming STT)
        ↓
OpenClaw API (port 8080)
        ↓ loads character JSON from P5
    System prompt construction
        ↓
    Ollama LLM (P2) — llama3.3:70b
        ↓ response + tool calls
    Skill dispatcher
        ├── home_assistant.py  → HA REST API (P1)
        ├── memory.py          → mem0 (local)
        ├── vtube_studio.py    → VTube WS (P7)
        ├── comfyui.py         → ComfyUI API (P8)
        ├── music.py           → Music Assistant (Phase 7)
        └── weather.py         → HA sensor data
        ↓ final response text
    TTS dispatch:
        ├── Chatterbox (voice clone, if active)
        └── Kokoro (via Wyoming, fallback)
        ↓
    Audio playback to appropriate room
```

## OpenClaw Setup

### Installation

```bash
# Confirm OpenClaw supports Ollama — check repo for latest install method
pip install openclaw
# or
git clone https://github.com/<openclaw-repo>/openclaw
pip install -e .
```

**Key question:** Verify OpenClaw's Ollama/OpenAI-compatible backend support before installation. If OpenClaw doesn't support local Ollama natively, use a thin adapter layer pointing its OpenAI endpoint at `http://localhost:11434/v1`.

### Config — `~/.openclaw/config.yaml`

```yaml
version: 1

llm:
  provider: ollama          # or openai-compatible
  base_url: http://localhost:11434/v1
  model: llama3.3:70b
  fast_model: qwen2.5:7b    # used for quick intent classification

character:
  active: aria
  config_dir: ~/.openclaw/characters/

memory:
  provider: mem0
  store_path: ~/.openclaw/memory/
  embedding_model: nomic-embed-text
  embedding_url: http://localhost:11434/v1

api:
  host: 0.0.0.0
  port: 8080

tts:
  primary: chatterbox       # when voice clone active
  fallback: kokoro-wyoming  # Wyoming TTS endpoint
  wyoming_tts_url: tcp://localhost:10301

wake:
  endpoint: /wake           # openWakeWord POSTs here to trigger listening
```

---

## Skills

All skills live in `~/.openclaw/skills/` (symlinked from `homeai-agent/skills/`).

### `home_assistant.py`

Wraps the HA REST API for common smart home actions.

**Functions:**
- `turn_on(entity_id, **kwargs)` — lights, switches, media players
- `turn_off(entity_id)`
- `toggle(entity_id)`
- `set_light(entity_id, brightness=None, color_temp=None, rgb_color=None)`
- `run_scene(scene_id)`
- `get_state(entity_id)` → returns state + attributes
- `list_entities(domain=None)` → returns entity list

Uses `HA_URL` and `HA_TOKEN` from `.env.services`.

### `memory.py`

Wraps mem0 for persistent long-term memory.

**Functions:**
- `remember(text, category=None)` — store a memory
- `recall(query, limit=5)` — semantic search over memories
- `forget(memory_id)` — delete a specific memory
- `list_recent(n=10)` — list most recent memories

mem0 uses `nomic-embed-text` via Ollama for embeddings.

### `weather.py`

Pulls weather data from Home Assistant sensors (local weather station or HA weather integration).

**Functions:**
- `get_current()` → temp, humidity, conditions
- `get_forecast(days=3)` → forecast array

### `timer.py`

Simple timer/reminder management.

**Functions:**
- `set_timer(duration_seconds, label=None)` → fires HA notification/TTS on expiry
- `set_reminder(datetime_str, message)` → schedules future TTS playback
- `list_timers()`
- `cancel_timer(timer_id)`

### `music.py` (stub — completed in Phase 7)

```python
def play(query: str): ...      # "play jazz" → Music Assistant
def pause(): ...
def skip(): ...
def set_volume(level: int): ... # 0-100
```

### `vtube_studio.py` (implemented in P7)

Stub in P4, full implementation in P7:
```python
def trigger_expression(event: str): ...   # "thinking", "happy", etc.
def set_parameter(name: str, value: float): ...
```

### `comfyui.py` (implemented in P8)

Stub in P4, full implementation in P8:
```python
def generate(workflow: str, params: dict) -> str: ...  # returns image path
```

## mem0 — Long-Term Memory

### Setup

```bash
pip install mem0ai
```

### Config

```python
from mem0 import Memory

config = {
    "llm": {
        "provider": "ollama",
        "config": {
            "model": "llama3.3:70b",
            "ollama_base_url": "http://localhost:11434",
        }
    },
    "embedder": {
        "provider": "ollama",
        "config": {
            "model": "nomic-embed-text",
            "ollama_base_url": "http://localhost:11434",
        }
    },
    "vector_store": {
        "provider": "chroma",
        "config": {
            "collection_name": "homeai_memory",
            "path": "~/.openclaw/memory/chroma",
        }
    }
}

memory = Memory.from_config(config)
```

> **Decision point:** Start with Chroma (local file-based). If semantic recall quality is poor, migrate to Qdrant (Docker container).

### Backup

Daily cron (via launchd) commits mem0 data to Gitea:

```bash
#!/usr/bin/env bash
cd ~/.openclaw/memory
git add .
git commit -m "mem0 backup $(date +%Y-%m-%d)"
git push origin main
```

---

## n8n Workflows

n8n runs in Docker (deployed in P1). Workflows exported as JSON and stored in `homeai-agent/workflows/`.

### Starter Workflows

**`morning-briefing.json`**
- Trigger: time-based (e.g., 7:30 AM on weekdays)
- Steps: fetch weather → fetch calendar events → compose briefing → POST to OpenClaw TTS → speak aloud

**`notification-router.json`**
- Trigger: HA webhook (new notification)
- Steps: classify urgency → if high: TTS immediately; if low: queue for next interaction

**`memory-backup.json`**
- Trigger: daily schedule
- Steps: commit mem0 data to Gitea

### n8n ↔ OpenClaw Integration

OpenClaw exposes a webhook endpoint that n8n can call to trigger TTS or run a skill:

```
POST http://localhost:8080/speak
{
  "text": "Good morning. It is 7:30 and the weather is...",
  "room": "all"
}
```

## API Surface (OpenClaw)

Key endpoints consumed by other projects:

| Endpoint | Method | Description |
|---|---|---|
| `/chat` | POST | Send text, get response (+ fires skills) |
| `/wake` | POST | Wake word trigger from openWakeWord |
| `/speak` | POST | TTS only — no LLM, just speak text |
| `/skill/<name>` | POST | Call a specific skill directly |
| `/memory` | GET/POST | Read/write memories |
| `/status` | GET | Health check |

## Interface Contracts

**Consumes:**
- Ollama API: `http://localhost:11434/v1`
- HA API: `$HA_URL` with `$HA_TOKEN`
- Wyoming TTS: `tcp://localhost:10301`
- Character JSON: `~/.openclaw/characters/<active>.json` (from P5)

**Exposes:**
- OpenClaw HTTP API: `http://localhost:8080` — consumed by P3 (voice), P7 (visual triggers), P8 (image skill)

**Add to `.env.services`:**
```dotenv
OPENCLAW_URL=http://localhost:8080
```

## Implementation Steps

- [ ] Confirm OpenClaw installation method and Ollama compatibility
- [ ] Install OpenClaw, write `config.yaml` pointing at Ollama and HA
- [ ] Verify OpenClaw responds to a basic text query via `/chat`
- [ ] Write `home_assistant.py` skill — test lights on/off via voice
- [ ] Write `memory.py` skill — test store and recall
- [ ] Write `weather.py` skill — verify HA weather sensor data
- [ ] Write `timer.py` skill — test set/fire a timer
- [ ] Write skill stubs: `music.py`, `vtube_studio.py`, `comfyui.py`
- [ ] Set up mem0 with Chroma backend, test semantic recall
- [ ] Write and test memory backup launchd job
- [ ] Deploy n8n via Docker (P1 task if not done)
- [ ] Build morning briefing n8n workflow
- [ ] Symlink `homeai-agent/skills/` → `~/.openclaw/skills/`
- [ ] Verify full voice → agent → HA action flow (with P3 pipeline)

---

## Success Criteria

- [ ] "Turn on the living room lights" → lights turn on via HA
- [ ] "Remember that I prefer jazz in the mornings" → mem0 stores it; "What do I like in the mornings?" → recalls it
- [ ] Morning briefing n8n workflow fires on schedule and speaks via TTS
- [ ] OpenClaw `/status` returns healthy
- [ ] OpenClaw survives Mac Mini reboot (launchd or Docker — TBD based on OpenClaw's preferred run method)
