Fulloch

The Fully Local Home Voice Assistant

A privacy-focused voice assistant that runs speech recognition, text-to-speech, and language model inference entirely on-device with no cloud dependencies.

Features

• 100% Local Processing: All AI runs on your hardware
• Privacy First: No data leaves your device for AI processing
• Low Latency: Optimized for real-time voice interaction
• Extensible: Easy to add new smart home integrations

Prerequisites

• Python 3.10+
• CUDA-capable GPU (recommended) or CPU
• ~4GB disk space for models
• Microphone and speakers

Quick Start

1. Clone and Install

git clone https://github.com/liampetti/fulloch.git
cd fulloch
pip install -r requirements.txt

2. Configure

cp data/config.example.yml data/config.yml
cp .env.example .env

Edit data/config.yml with your settings (see Configuration section below).

3. Download Models

The launch script handles model downloads automatically:

./launch.sh

Or manually download:

• Qwen3-4B-Instruct GGUF → data/models/
• Moonshine and Kokoro download automatically on first run

4. Run

python app.py

Say your wakeword (default: "computer") followed by a command.

Docker Deployment

./launch.sh  # Downloads models, configures GPU/CPU, starts services

The launch script:

1. Downloads required models if not present
2. Detects GPU availability
3. Starts the assistant and SearXNG search service

Configuration

General Settings

general:
  wakeword: "computer"       # Activation phrase

Spotify

1. Create an app at Spotify Developer Dashboard
2. Add http://localhost:8888/callback as redirect URI
3. Configure:

spotify:
  client_id: "your_client_id"
  client_secret: "your_client_secret"
  redirect_uri: "http://localhost:8888/callback"
  device_id: "Your Speaker Name"
  use_avr: false             # Enable Pioneer AVR integration when playing music (turn on amplifier/sound system before playing music)

Philips Hue

1. Press the button on your Hue Bridge
2. Run the app to auto-register
3. Configure:

philips:
  hue_hub_ip: "192.168.1.100"

Google Calendar

1. Create credentials at Google Cloud Console
2. Enable Google Calendar API
3. Download OAuth credentials JSON
4. Configure:

google:
  cred_file: "./data/credentials.json"
  token_file: "./data/token.json"

BOM Australia Weather

bom:
  default: "Sydney"          # Default location for weather

Home Assistant

Connect to a Home Assistant instance to control all your devices through a single integration.

1. Create a Long-Lived Access Token in your HA profile (http://your-ha:8123/profile)
2. Configure:

home_assistant:
  enabled: true                    # Must be explicitly enabled
  url: "http://192.168.1.50:8123"
  token: "your_long_lived_token"
  entity_aliases:                  # Map friendly names to entity IDs
    living room lights: "light.living_room"
    front door: "lock.front_door"

Important: The Home Assistant integration is disabled by default. When enabled, it registers generic tool names like turn_on, turn_off, and toggle which may conflict with other integrations (e.g., Philips Hue lighting tools). Only enable this if you want Home Assistant to be your primary home automation controller.

If you use both Home Assistant and direct integrations (like Philips Hue), keep enabled: false and use the direct integrations instead.

Other Integrations

See data/config.example.yml for all available integrations:

• LG ThinQ (smart appliances)
• WebOS TV control
• Pioneer/Onkyo AVR
• Airtouch HVAC
• SearXNG web search

Troubleshooting

No audio input detected

• Check microphone permissions
• Verify microphone is set as default input device
• Adjust SILENCE_THRESHOLD in core/audio.py if too sensitive/insensitive

Model loading fails

• Ensure sufficient disk space (~4GB)
• Check CUDA installation if using GPU
• Verify model files are in data/models/

Spotify not working

• Run python tools/spotify.py to test authentication
• Verify redirect URI matches in Spotify Dashboard
• Check that Spotify device is active

High CPU/Memory usage

• Use GPU acceleration if available
• Reduce N_CONTEXT in core/slm.py for less memory
• Disable SLM for basic commands only (set SLM_MODEL = "")
