**Status**: These are in backlog, ready to implement when you have hardware.
## 🚀 What You CAN Test on Pi5 Right Now
### 1. MCP Server & Tools
```bash
# On Pi5:
cd /home/beast/Code/atlas/home-voice-agent/mcp-server
pip install -r requirements.txt
./run.sh
# Test from another device:
curl http://<pi5-ip>:8000/health
```
### 2. Web Dashboard
```bash
# On Pi5:
# Start MCP server (see above)
# Access from browser:
http://<pi5-ip>:8000
```
### 3. Phone PWA

- Access from phone browser
- Test text input, conversation persistence
- Test LLM routing (work/family agents)
### 4. LLM Integration
- Connect to remote 4080 LLM server
- Test tool calling
- Test memory system
- Test conversation management
## 📋 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
```bash
# 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
```bash
cd ~/atlas/home-voice-agent/mcp-server
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```
### Step 3: Configure Environment
```bash
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
```bash
# 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
```bash
# 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**:
```bash
# 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**:
```bash
# 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**:
```bash
# 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
