📋 Pi5 Setup Checklist
Prerequisites
- Pi5 with OS installed (Raspberry Pi OS recommended)
- Python 3.8+ installed
- Network connectivity (WiFi or Ethernet)
- USB microphone (for voice testing later)
- MicroSD card (64GB+ recommended)
Step 1: Initial Setup
# On Pi5:
sudo apt update && sudo apt upgrade -y
sudo apt install -y python3-pip python3-venv git
# Clone or copy the repository
cd ~
git clone <your-repo-url> atlas
# OR copy from your dev machine
Step 2: Install Dependencies
cd ~/atlas/home-voice-agent/mcp-server
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
Step 3: Configure Environment
cd ~/atlas/home-voice-agent
# Create .env file
cp .env.example .env
# Edit .env for Pi5 deployment:
# - Set OLLAMA_HOST to your 4080 server IP
# - Set OLLAMA_PORT to 11434
# - Configure model names
Step 4: Test Core Services
# Test MCP server
cd mcp-server
./run.sh
# In another terminal, test:
curl http://localhost:8000/health
curl http://localhost:8000/api/dashboard/status
Step 5: Access from Network
# Find Pi5 IP address
hostname -I
# From another device:
# http://<pi5-ip>:8000
🎤 Voice I/O Setup (When Ready)
Wake-Word Detection (TICKET-006)
Status: Ready to implement Requirements:
- USB microphone connected
- Python audio libraries (PyAudio, sounddevice)
- Wake-word engine (openWakeWord or Porcupine)
Implementation:
# Install audio dependencies
sudo apt install -y portaudio19-dev python3-pyaudio
# Install wake-word engine
pip install openwakeword # or porcupine
ASR Service (TICKET-010)
Status: Ready to implement Requirements:
- faster-whisper or Whisper.cpp
- Audio capture (PyAudio)
- WebSocket server
Implementation:
# Install faster-whisper
pip install faster-whisper
# Or use Whisper.cpp (lighter weight for Pi5)
# See ASR_EVALUATION.md for details
Note: ASR can run on:
- Option A: Pi5 CPU (slower, but works)
- Option B: RTX 4080 server (recommended, faster)
TTS Service (TICKET-014)
Status: Ready to implement Requirements:
- Piper, Mimic 3, or Coqui TTS
- Audio output (speakers/headphones)
Implementation:
# Install Piper (lightweight, recommended for Pi5)
# See TTS_EVALUATION.md for details
🔧 Pi5-Specific Considerations
Performance
- Pi5 Specs: Much faster than Pi4, but still ARM
- Recommendation: Run wake-word on Pi5, ASR on 4080 server
- Memory: 4GB+ RAM recommended
- Storage: Use fast microSD (Class 10, A2) or USB SSD
Power
- Official 27W power supply required for Pi5
- Cooling: Active cooling recommended for sustained load
- Power consumption: ~5-10W idle, ~15-20W under load
Audio
- USB microphones: Plug-and-play, recommended
- 3.5mm audio: Can use for output (speakers)
- HDMI audio: Alternative for output
Network
- Ethernet: Recommended for stability
- WiFi: Works, but may have latency
- Firewall: May need to open port 8000
