## Next Steps for You
### 1. Transfer to Raspberry Pi
From your Windows machine, transfer the project to your Raspberry Pi:
```powershell
# Using scp (you have raspberrypi.local in your SSH known_hosts)
scp -r C:\intraffic\DigitalPianoPicnic pi@raspberrypi.local:~/
# Or use git (recommended)
cd C:\intraffic\DigitalPianoPicnic
git init
git add .
git commit -m "Initial implementation"
git push <your-remote-repo>
# Then on the Pi:
# git clone <your-repo-url> ~/DigitalPianoPicnic
```
### 2. Run Setup on Raspberry Pi
SSH into your Raspberry Pi and run the automated setup:
```bash
ssh pi@raspberrypi.local
cd ~/DigitalPianoPicnic
chmod +x setup.sh deployment/install-service.sh
./setup.sh
```
This will:
- Install system dependencies (libasound2-dev)
- Install Python dependencies
- Create config files from templates
- Prompt for your HA token
- List available MIDI ports
### 3. Configure Your Setup
Edit the configuration files:
```bash
nano config/app.yaml
```
**Required changes:**
1. Set `ha.url` to your Home Assistant WebSocket URL (or use default)
2. Set `announce.device_id` to your Assist Satellite device ID
3. Optionally change arming `sequence` to your preferred notes
```bash
nano config/mapping.yaml
```
**Required changes:**
1. Set `defaults.config_entry_id` to your Picnic integration ID (see below)
2. Map MIDI notes (60, 61, 62, etc.) to your Picnic product IDs
3. Set product names for announcements
4. Set amounts per product
**Finding config_entry_id:**
- Navigate to Settings → Devices & Services → Picnic integration in Home Assistant
- Copy the ID from the URL after `/config/integration/`
- Example: If URL is `.../config/integration/01JEN4FWWJ123ABCDEF456789`, use `01JEN4FWWJ123ABCDEF456789`
**Finding Product IDs:**
**Option 1: Web Interface (Easiest)**
```bash
# Set credentials
export PICNIC_USERNAME='your@email.com'
export PICNIC_PASSWORD='yourpassword'
# Start web server
python3 tools/search_web.py
# Open http://localhost:8080
# Search → Select keyboard key → Click "Save to Config"
```
**Option 2: Command-Line Tool**
```bash
# Interactive mode
python3 tools/search_products.py --interactive
# Single search
python3 tools/search_products.py "product name"
```
**Finding Picnic Config Entry ID (REQUIRED!):**
1. Go to Settings → Devices & Services in Home Assistant
2. Click on the **Picnic** integration card
3. Look at the URL: `http://homeassistant.local:8123/config/integrations/integration/01JEN4FWWJ...`
4. Copy the ID after `/integration/` (e.g., `01JEN4FWWJ123ABCDEF456789`)
5. Add to `config/mapping.yaml`: `defaults.config_entry_id: "01JEN4FWWJ123ABCDEF456789"`
**Finding Picnic Product IDs:**
1. Open Picnic app and add a product to cart
2. In Home Assistant, go to Developer Tools → States
3. Find `sensor.picnic_cart_items`
4. Look at the state attributes for product IDs
**Finding Assist Satellite Device ID:**
1. Go to Settings → Devices & Services in Home Assistant
2. Click on your Assist Satellite device
3. Copy the device ID from the URL bar
### 4. Test Manually
Test the bridge before installing as a service:
```bash
cd ~/DigitalPianoPicnic
# Test mode (no Home Assistant required):
python3 src/bridge.py --test
# Real mode (requires HA_TOKEN):
python3 src/bridge.py
```
**Testing checklist (test mode):**
- [ ] MIDI port detected and opened
- [ ] Arming sequence works (play C-D-E or your custom sequence)
- [ ] System logs "System ARMED"
- [ ] Play a mapped key twice quickly
- [ ] System logs "[TEST MODE] Would add product..."
- [ ] System logs "[TEST MODE] Would announce..."
**Additional checks (real mode):**
- [ ] Product is added to Picnic cart
- [ ] Announcement is heard on Assist Satellite
- [ ] Check Home Assistant logs for service calls
### 5. Install as System Service
Once testing is successful, install as a service to run on boot:
```bash
sudo ./deployment/install-service.sh
```
This will:
- Copy service file to /etc/systemd/system/
- Enable the service for autostart
- Optionally start it immediately
- Show service status
**Service management:**
```bash
# View logs
sudo journalctl -u midi-ha.service -f
# Restart after config changes
sudo systemctl restart midi-ha.service
# Check status
sudo systemctl status midi-ha.service
```
### 6. Usage
Once the service is running:
1. **Arm**: Play your password sequence (default: Middle C, D, E)
2. **Shop**: Play any mapped key twice within 800ms
3. **Listen**: Hear the product name announced
4. **Continue**: Add more products (system stays armed)
5. **Wait**: System auto-disarms after 60s of inactivity
## Configuration Tips
### MIDI Note Numbers Reference
Middle C (C4) = 60, then:
- C4=60, C#4=61, D4=62, D#4=63, E4=64, F4=65, F#4=66, G4=67, G#4=68, A4=69, A#4=70, B4=71
- C5=72, C#5=73, D5=74... (add 12 per octave)
Most digital pianos have Middle C near the center. You can test by running:
```bash
python3 src/midi.py
```
Then press keys to see their note numbers.
### Recommended Settings
**For beginners:**
- Simple sequence: `[60, 62, 64]` (C-D-E)
- Longer double-tap window: `1000ms`
- Keep announcements enabled
- Set `disarm_after_add: false` (stay armed)
**For advanced users:**
- Complex sequence: `[60, 62, 64, 65, 67]` (C-D-E-F-G)
- Or use chord arming: `chord: [60, 64, 67]` (C major chord)
- Shorter double-tap: `600ms`
- Enable `disarm_after_add: true` for security
**For mapping:**
- Map frequently-used products to white keys near middle C
- Use sharps/flats for less common items
- Higher octaves for categories (drinks, snacks, etc.)
## Troubleshooting
See README.md "Troubleshooting" section for common issues.
**Quick diagnostics:**
```bash
# Check MIDI device connected
lsusb
amidi -l
# Check Home Assistant connectivity
curl -v ws://homeassistant.local:8123/api/websocket
# Check Python dependencies
pip3 list | grep -E "mido|rtmidi|websockets|yaml"
# Test each module independently
python3 src/midi.py # MIDI input test
python3 src/ha_client.py # HA client test (needs HA_TOKEN env var)
python3 src/bridge.py --test # Keyboard test (no HA needed)
python3 src/bridge.py # Full bridge test (needs HA)
```
curl -v ws://homeassistant.local:8123/api/websocket
# Check Python dependencies
pip3 list | grep -E "mido|rtmidi|websockets|yaml"

# 🎹 Quick Start Guide
Get your digital piano shopping in **5 minutes**!
## Prerequisites Check
✅ Raspberry Pi with Raspbian OS
✅ Digital piano connected via USB
✅ Home Assistant running with Picnic integration
✅ Home Assistant Assist Satellite configured
## Step 1: Transfer Files
From your Windows machine:
```powershell
# Option A: Using SCP
scp -r C:\intraffic\DigitalPianoPicnic pi@raspberrypi.local:~/
# Option B: Using Git (recommended)
cd C:\intraffic\DigitalPianoPicnic
git init
git add .
git commit -m "Initial setup"
# Push to your repo, then clone on Pi
```
## Step 2: Run Setup (on Raspberry Pi)
```bash
ssh pi@raspberrypi.local
cd ~/DigitalPianoPicnic
chmod +x setup.sh
./setup.sh
```
When prompted, paste your Home Assistant Long-Lived Access Token (get it from `http://homeassistant.local:8123/profile`).
## Step 3: Configure
### Get Your Device ID
In Home Assistant:
1. Settings → Devices & Services
2. Click your Assist Satellite device
3. Copy the ID from the URL (e.g., `4f17bb6b7102f82e8a91bf663bcb76f9`)
### Edit Main Config
```bash
nano config/app.yaml
```
Change line 3 to your HA URL (or keep default):
```yaml
url: ws://homeassistant.local:8123/api/websocket
```
Change line 58 to your Assist Satellite device ID:
```yaml
device_id: YOUR_DEVICE_ID_HERE
```
Save: `Ctrl+X`, `Y`, `Enter`
### Map Your Products
```bash
nano config/mapping.yaml
```
Find Picnic product IDs:
1. Add products to cart in Picnic app
2. In Home Assistant: Developer Tools → States → `sensor.picnic_cart_items`
3. Copy product IDs from attributes
Update note mappings (example):
```yaml
notes:
60: # Middle C
product_id: s1018231
product_name: "Picnic cola zero"
amount: 1
```
Save: `Ctrl+X`, `Y`, `Enter`
## Step 4: Test
```bash
# Test mode first (no Home Assistant needed):
python3 src/bridge.py --test
# Then test with Home Assistant:
python3 src/bridge.py
```
**Test sequence:**
1. Play C-D-E (arming sequence) → Should see "System ARMED"
2. Play Middle C twice quickly → Should see product action
- Test mode: "[TEST MODE] Would add product..."
- Real mode: Actually adds to cart + hear announcement
3. Press `Ctrl+C` to stop
## Step 5: Install Service
```bash
sudo ./deployment/install-service.sh
```
When prompted:
- Enter your HA token (same as before)
- Choose `Y` to start now
## Step 6: Verify
```bash
sudo systemctl status midi-ha.service
sudo journalctl -u midi-ha.service -f
```
You should see:
- "Connected and authenticated to Home Assistant"
- "Listening for MIDI events..."
## Usage
1. **Arm**: Play C-D-E (or your custom sequence)
2. **Shop**: Play any mapped key **twice** within 800ms
3. **Hear**: Product name announced
4. **Repeat**: Add more items (stays armed for 60s)
## Customize
### Change Arming Password
Edit `config/app.yaml`, line 34:
```yaml
sequence: [60, 64, 67] # Change to C-E-G (C major chord notes)
```
MIDI note reference: Middle C=60, then +1 per semitone (C#=61, D=62, etc.)
### Change Double-Tap Speed
Edit `config/app.yaml`, line 49:
```yaml
double_tap_window_ms: 1000 # Make it easier (was 800)
```
### Map More Products
Edit `config/mapping.yaml`, add more notes:
```yaml
notes:
61: # C#
product_id: s2222222
product_name: "Milk"
amount: 1
```
**After any config change:**
```bash
sudo systemctl restart midi-ha.service
```
## Troubleshooting
### "No MIDI ports found"
```bash
lsusb # Check USB device connected
amidi -l # List MIDI ports
```
### "Authentication failed"
- Regenerate token in Home Assistant
- Update in service: `sudo nano /etc/systemd/system/midi-ha.service`
- Restart: `sudo systemctl restart midi-ha.service`
### "Product not added"
- Check product ID is correct (case-sensitive!)
- Test in HA Developer Tools: Services → `picnic.add_product`
### "No announcement"
- Check device ID is correct
- Test in HA Developer Tools: Services → `assist_satellite.announce`
- Verify satellite is online
### "Want to test without Home Assistant?"
```bash
python3 src/bridge.py --test
```
See `TEST_MODE.md` for full testing guide.
## Getting MIDI Note Numbers
Run test mode:
```bash
python3 src/midi.py
```
Press keys on your piano to see their note numbers. Press `Ctrl+C` to stop.
## Tips
- 🎼 Map frequently-used items to white keys near middle C
- 🎵 Use black keys for less common items
- 🎶 Higher octaves for different product categories
- 🎹 Practice your arming sequence so it's muscle memory
- 🔊 Adjust announcement volume in Home Assistant

# Digital Piano → Home Assistant Picnic Shopping Cart
Build your Picnic shopping cart by playing your digital piano! This project bridges MIDI input from a piano connected to a Raspberry Pi to Home Assistant, allowing each piano key to add a product to your Picnic cart with voice confirmation.
## Features
✨ **Password Protection**: Requires a note sequence or chord before shopping actions are enabled
🎹 **Double-Tap Confirmation**: Each key must be played twice to prevent accidental additions
🔊 **Voice Announcements**: Home Assistant announces when system is armed and when products are added via Assist Satellite
⚡ **Rate Limiting**: Prevents duplicate additions from stuck keys or rapid presses
🔄 **Auto-Reconnect**: Automatically reconnects if keyboard or Home Assistant disconnects
🛡️ **Auto-Disarm**: Automatically returns to safe state after inactivity with voice notification
🎵 **88-Key Support**: Map any MIDI note (0-127) to any Picnic product
## Architecture
```
Digital Piano (USB) → Raspberry Pi (Python) → Home Assistant (WebSocket) → Picnic API
```
The bridge runs on a Raspberry Pi, reading MIDI events via `mido` and `python-rtmidi`, then triggering Home Assistant services (`picnic.add_product` and `assist_satellite.announce`) over WebSocket.
## Quick Start
### Prerequisites
- **Hardware**: Raspberry Pi 3B+/4/5 with Raspbian OS, digital piano with USB MIDI
- **Home Assistant**: Running instance with Picnic and Assist Satellite integrations configured
- **Python**: 3.9+ (pre-installed on Raspbian Bookworm)
### Installation
1. **Clone the repository:**
```bash
git clone <your-repo-url> ~/DigitalPianoPicnic
cd ~/DigitalPianoPicnic
```
2. **Install system dependencies:**
```bash
sudo apt-get update
sudo apt-get install -y libasound2-dev python3-pip
```
3. **Install Python dependencies (using virtual environment):**
```bash
python3 -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt
```
4. **Configure the application:**
```bash
# Copy example configs
cp config/app.yaml.example config/app.yaml
cp config/mapping.yaml.example config/mapping.yaml
# Edit configs with your settings
nano config/app.yaml # Set HA URL and device ID
nano config/mapping.yaml # Map notes to products
# Set your Home Assistant token
echo 'export HA_TOKEN="your-long-lived-token-here"' >> ~/.bashrc
source ~/.bashrc
```
5. **Test manually:**
```bash
source venv/bin/activate
# Test mode (no Home Assistant required, just keyboard/MIDI):
python3 src/bridge.py --test
# Real mode (requires HA_TOKEN and Home Assistant connection):
python3 src/bridge.py
```
**Test mode:**
- Tests MIDI input, arming sequence, double-tap, and rate limiting
- Fakes Home Assistant calls (no actual products added)
- Perfect for verifying keyboard functionality
**Real mode:**
- Play the arming sequence (default: C-D-E)
- Play a mapped key twice quickly
- Verify product is added and announced
6. **Install as system service:**
```bash
# Edit service file with your token
sudo nano deployment/midi-ha.service
# Install and start
sudo cp deployment/midi-ha.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable midi-ha.service
sudo systemctl start midi-ha.service
# Check status
sudo systemctl status midi-ha.service
sudo journalctl -u midi-ha.service -f
```
## Configuration
### Arming Sequence
Edit `config/app.yaml` to set your password:
```yaml
arming:
enabled: true
sequence: [60, 62, 64] # C, D, E (Middle C = MIDI note 60)
sequence_timeout_ms: 3000
```
**MIDI Note Reference**: C4=60, C#4=61, D4=62, D#4=63, E4=64, F4=65, F#4=66, G4=67, G#4=68, A4=69, A#4=70, B4=71, C5=72...
### Product Mapping
Edit `config/mapping.yaml` to assign products to keys:
```yaml
notes:
60: # Middle C
product_id: s1018231
product_name: "Picnic cola zero"
amount: 1
```
Find Picnic product IDs:
**Option 1: Use the search tool (recommended)**
```bash
# Install the optional tool
pip install python-picnic-api
# Set credentials (secure method)
export PICNIC_USERNAME='your@email.com'
export PICNIC_PASSWORD='yourpassword'
# Search for products
python3 tools/search_products.py "coca cola zero"
python3 tools/search_products.py --interactive
# See tools/README.md for full documentation
```
**Option 3: Manual Lookup via Home Assistant**
1. Open Picnic app/website
2. Add product to cart
3. Check Home Assistant Developer Tools → States → `sensor.picnic_cart_items`
4. Look for `product_id` in the state attributes
Find Picnic config_entry_id (REQUIRED):
1. Go to Home Assistant → Settings → Devices & Services
2. Click on the **Picnic** integration
3. Copy the ID from the URL after `/integration/` (e.g., `01JEN4FWWJ123ABCDEF456789`)
4. Add it to `config/mapping.yaml` under `defaults.config_entry_id`
Update `config/mapping.yaml`:
```yaml
defaults:
config_entry_id: "01JEN4FWWJ123ABCDEF456789" # From Picnic integration URL
```
### Voice Announcements
Find your Assist Satellite device ID:
1. Go to Home Assistant → Settings → Devices & Services
2. Find your Assist Satellite device
3. Click on it and copy the device ID from the URL
Update `config/app.yaml`:
```yaml
announce:
enabled: true
device_id: 4f17bb6b7102f82e8a91bf663bcb76f9
message_template: "{product_name} was added to basket"
```
## Usage
1. **Arm the system**: Play the password sequence (default: C-D-E)
2. **Add products**: Play any mapped key twice within 800ms
3. **Listen**: Home Assistant announces the product name
4. **Auto-disarm**: System disarms after 60 seconds of inactivity
### Tips
- Use a memorable melody as your password (4+ notes recommended)
- Map frequently-used products to convenient keys (white keys near middle C)
- Adjust `double_tap_window_ms` if you have difficulty with timing
- Set `disarm_after_add: true` for extra security (requires re-arming after each product)
## Troubleshooting
### No MIDI ports detected
```bash
# List USB devices
lsusb
# List MIDI ports
amidi -l
# Test MIDI input
aseqdump -p <port>
```
### WebSocket connection fails
```bash
# Test connectivity
curl -v ws://homeassistant.local:8123/api/websocket
# Use IP address if .local doesn't resolve
# Update config/app.yaml with: ws://192.168.1.100:8123/api/websocket
```
### Service won't start
```bash
# Check logs
sudo journalctl -u midi-ha.service -n 50 --no-pager
# Check HA_TOKEN is set in service file
sudo systemctl cat midi-ha.service
# Test manually
HA_TOKEN="your-token" python3 src/bridge.py
```
### Products not adding
- Verify Picnic integration is configured in Home Assistant
- Check product IDs are correct (case-sensitive)
- Review logs: `sudo journalctl -u midi-ha.service -f`
- Test service call in HA Developer Tools
### Announcements not working
- Verify Assist Satellite device ID is correct
- Test announcement manually in HA Developer Tools
- Check device is online and responding
### Piano disconnected
**Symptom**: `MIDI connection lost` in logs
**Solution**: The system automatically tries to reconnect every 5 seconds. Just plug the keyboard back in or power it on.
**Security**: The arming state is automatically reset to DISARMED when the device disconnects, so you'll need to re-enter your password sequence after reconnection.
To change reconnect delay, edit `config/app.yaml`:
```yaml
runtime:
midi_reconnect_delay_sec: 10 # Wait 10 seconds between retries
```

```
## What Test Mode Does
✅ **Enabled:**
- MIDI input reading
- Port detection and selection
- Arming sequence detection
- Chord detection (if configured)
- Double-tap confirmation tracking
- Rate limiting enforcement
- Configuration file loading
- Note-to-product mapping lookups
- Full logging of all actions
❌ **Disabled:**
- Home Assistant WebSocket connection
- Actual `picnic.add_product` service calls
- Actual `assist_satellite.announce` service calls
- HA_TOKEN requirement
## Test Mode Output
When you trigger an action in test mode, you'll see:
```
2025-12-11 14:32:45 [INFO] bridge: Bridge starting in TEST MODE (no Home Assistant connection)

## Common Test Scenarios
### Test 1: Basic Flow
```
Action: Play C-D-E
Expected: "System ARMED (sequence)"
Action: Play Middle C once
Expected: "waiting for second tap"
Action: Play Middle C again (within 800ms)
Expected: "[TEST MODE] Would add product: ..."
```
### Test 2: Wrong Sequence
```
Action: Play C-E-D (wrong order)
Expected: "Sequence broken, restarting"
Action: System stays DISARMED
Expected: No products triggered
```
### Test 3: Slow Double-Tap
```
Action: Play Middle C
Expected: "waiting for second tap"
Action: Wait 1 second
Action: Play Middle C again
Expected: "Double-tap expired, reset" + "waiting for second tap"
```
### Test 4: Rate Limiting
```
Action: Play C-D-E to arm
Action: Double-tap Middle C successfully
Expected: Product add
Action: Immediately double-tap Middle C again
Expected: "Rate limited"
Action: Wait 1 second, double-tap Middle C
Expected: Product add works
```
## Switching to Real Mode
Once test mode works perfectly:
1. **Set HA_TOKEN:**
```bash
export HA_TOKEN="your-long-lived-token-here"
```
2. **Run without --test flag:**
```bash
python3 src/bridge.py
```
3. **Verify HA connection:**
```
[INFO] bridge: Connected and authenticated to Home Assistant
```
4. **Test one product add:**
- Arm with sequence
- Double-tap a mapped key
- Check Picnic cart in HA
- Listen for announcement
## Troubleshooting Test Mode
### "No MIDI ports found"
```bash
# Check USB connection
lsusb
# List MIDI devices
amidi -l
# Test with standalone tool
python3 src/midi.py
```
### "Config file not found"
```bash
# Check you're in the right directory
pwd
# Should be: /home/pi/DigitalPianoPicnic
# Copy example configs if needed
cp config/app.yaml.example config/app.yaml
cp config/mapping.yaml.example config/mapping.yaml
```
### "No product mapping for note X"
Edit `config/mapping.yaml` and add the note:
```yaml
notes:
60: # Your note number
product_id: s1234567
product_name: "Your Product"
amount: 1
```
### Double-tap too hard/easy
Edit `config/app.yaml`:
```yaml
confirmation:
double_tap_window_ms: 1000 # Increase for easier timing
```
## Command Reference
```bash
# Test mode (no HA)
python3 src/bridge.py --test
# Real mode (requires HA)
python3 src/bridge.py
# Custom config in test mode
python3 src/bridge.py --test --config /path/to/config.yaml
# Help
python3 src/bridge.py --help
```
## Next Steps
After successful test mode validation:
1. ✅ MIDI functionality confirmed
2. ✅ Arming/disarming works
3. ✅ Double-tap timing tuned
4. ✅ Note mappings verified
5. ➡️ Switch to real mode with `HA_TOKEN`
6. ➡️ Test one product add manually
7. ➡️ Install as systemd service

# Arming System Voice Announcements
The MIDI bridge now announces when the piano system is armed or disarmed using Home Assistant's Assist Satellite service.
## Features
### Armed Announcement
When the system becomes armed (via sequence, chord, or both), it announces:
- **Default message**: "Piano is now armed and ready for shopping"
- Plays after successful sequence or chord completion
- Only announces when transitioning from disarmed to armed
### Disarmed Announcement
When the system disarms (timeout, manual reset), it announces:
- **Default message**: "Piano has been disarmed"
- Only announces when transitioning from armed to disarmed
## Configuration
Add these settings to your `config/app.yaml` under the `arming` section:
```yaml
arming:
enabled: true
sequence: [60, 62, 64] # Your arming sequence
# Voice announcements
announce_on_arm: true
announce_on_disarm: true
arm_message: "Piano is now armed and ready for shopping"
disarm_message: "Piano has been disarmed"
```
### Configuration Options
| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `announce_on_arm` | boolean | `true` | Enable announcement when system arms |
| `announce_on_disarm` | boolean | `true` | Enable announcement when system disarms |
| `arm_message` | string | See above | Message spoken when arming |
| `disarm_message` | string | See above | Message spoken when disarming |
## How It Works
1. **Arming Detection**: The `ArmingStateMachine` tracks state transitions
2. **Announcement Trigger**: When state changes to `ARMED`, announcement is queued
3. **HA Client**: Uses `assist_satellite.announce` service via the HA REST API
4. **Async Execution**: Announcements run in background without blocking MIDI processing
## Technical Details
### Code Changes
Modified `src/bridge.py`:
- Added `announce_on_arm`, `announce_on_disarm`, `arm_message`, `disarm_message` config
- Added `set_ha_client()` method to pass HA client to arming state machine
- Added `_announce()` async method to send announcements
- Added announcement calls in `on_note()` when arming via sequence
- Added announcement calls in `on_chord()` when arming via chord
- Added announcement call in `reset()` when disarming
### Device Selection
The announcement uses the device_id from the `announce` section of your config:
```yaml
announce:
enabled: true
device_id: 4f17bb6b7102f82e8a91bf663bcb76f9 # Your satellite device ID
```
If `device_id` is `None`, the announcement goes to all available satellites.
## Testing
1. Start the MIDI bridge: `sudo systemctl start midi-ha`
2. Play your arming sequence or chord
3. Listen for "Piano is now armed and ready for shopping"
4. Wait for auto-disarm timeout or press disarm keys
5. Listen for "Piano has been disarmed"
## Customization Examples
### Simple Messages
```yaml
arm_message: "System armed"
disarm_message: "System disarmed"
```
### Playful Messages
```yaml
arm_message: "Let's go shopping! Piano is ready."
disarm_message: "Shopping mode deactivated"
```
### Security-Style Messages
```yaml
arm_message: "Security sequence accepted. System armed."
disarm_message: "System has been secured"
```
### Multi-Language Support
Use your Home Assistant's language settings - the satellite will use its configured TTS language.
## Troubleshooting
### No Announcements Heard
1. **Check HA connection**: Look for "System ARMED" in logs
2. **Check satellite device**: Verify device_id in config
3. **Check satellite status**: Ensure satellite is online in HA
4. **Check announce config**: `announce.enabled: true` in config
5. **Check logs**: Look for "Arming announcement sent" messages
### Announcement Delayed
- Announcements are async and may have slight delay
- Network latency to Home Assistant
- TTS processing time on satellite
### Wrong Device Announces
- Verify `device_id` in config matches your satellite
- Find correct ID in HA: Settings → Devices → Your Satellite → Device ID in URL

x# Digital Piano → Home Assistant Picnic Shopping Cart Integration
## Overview
This project bridges MIDI input from a digital piano connected to a Raspberry Pi to Home Assistant actions. Each piano key can be mapped to a Picnic product, enabling you to build your shopping cart by playing notes. The system includes:
- **Arming mechanism**: Requires a password (note sequence or chord) before shopping actions are enabled
- **Double-tap confirmation**: Each note must be played twice within a time window to add a product
- **Voice announcements**: Home Assistant announces the added product via Assist Satellite
- **Rate limiting**: Prevents accidental duplicate additions
- **Automatic disarm**: Resets after inactivity for safety

"preannounce": false
},
"target": {
"device_id": "4f17bb6b7102f82e8a91bf663bcb76f9"
}
}
```
## Raspberry Pi Deployment
### Prerequisites
**Hardware:**
- Raspberry Pi (3B+, 4, or 5 recommended)
- Raspbian OS (Bookworm or Bullseye)
- Digital piano with USB MIDI output
**Software:**
- Python 3.9+ (pre-installed on Raspbian Bookworm)
- `libasound2` (ALSA library for MIDI)
- Git (for version control and deployment)
### Installation Steps
1. **Clone repository to Raspberry Pi:**
```bash
cd ~
git clone <your-repo-url> DigitalPianoPicnic
cd DigitalPianoPicnic
```
2. **Install system dependencies:**
```bash
sudo apt-get update
sudo apt-get install -y libasound2-dev python3-pip
```
3. **Install Python dependencies:**
```bash
pip3 install -r requirements.txt
```
4. **Configure application:**
- Copy `config/app.yaml.example` to `config/app.yaml`
- Copy `config/mapping.yaml.example` to `config/mapping.yaml`
- Edit both files with your Home Assistant URL, device ID, and note mappings
- Set `HA_TOKEN` environment variable:
```bash
echo 'export HA_TOKEN="your-long-lived-token"' >> ~/.bashrc
source ~/.bashrc
```
5. **Test manually:**
```bash
python3 src/bridge.py
```
- Verify MIDI port detection
- Test arming sequence
- Confirm double-tap and product adds
6. **Install systemd service:**
```bash
sudo cp deployment/midi-ha.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable midi-ha.service
sudo systemctl start midi-ha.service
```
7. **Verify logs:**
```bash
sudo journalctl -u midi-ha.service -f
```
### MIDI Device Permissions
If you encounter permission errors accessing MIDI devices:
```bash
# Add user to audio group
sudo usermod -aG audio $USER
# Create udev rule (optional, usually not needed)
echo 'SUBSYSTEM=="sound", MODE="0666"' | sudo tee /etc/udev/rules.d/99-midi.rules
sudo udevadm control --reload-rules
```
Log out and back in for group changes to take effect.
### Troubleshooting
**No MIDI ports detected:**
- Connect piano and run: `amidi -l`
- Check USB connection: `lsusb`
- Verify ALSA: `aplay -l`
**WebSocket connection fails:**
- Verify HA URL is correct (use IP if `.local` doesn't resolve)
- Check token validity in Home Assistant UI
- Test connectivity: `curl -v ws://homeassistant.local:8123/api/websocket`
**Service won't start:**
- Check logs: `sudo journalctl -u midi-ha.service -n 50`
- Verify paths in `midi-ha.service` match your installation
- Ensure `HA_TOKEN` is set in service environment
## Logging and Observability
### Log Levels
- **DEBUG**: All MIDI events, state transitions, payload details
- **INFO**: Service starts, arming/disarming, product adds, announcements
- **WARNING**: Rate limit hits, mapping misses, reconnections
- **ERROR**: Service call failures, WebSocket errors, config issues
### Structured Logging Format
```
[TIMESTAMP] [LEVEL] [MODULE] message key1=value1 key2=value2
```
Example:
```
2025-12-11 14:32:45 INFO bridge Armed state=armed trigger=sequence
2025-12-11 14:32:50 INFO bridge Product added note=60 product_id=s1018231 amount=1
2025-12-11 14:32:51 INFO ha_client Announcement sent device_id=4f17bb...
```
### Metrics to Monitor
- MIDI events per minute (to detect stuck keys)
- Arming/disarming frequency
- Product add success rate
- WebSocket reconnection count
- Average latency (MIDI event → HA response)
## Roadmap
### Phase 1: Core Functionality (Current)
- [x] Planning and architecture
- [x] MIDI input with `mido` and `python-rtmidi`
- [x] Home Assistant WebSocket client
- [x] Arming state machine (sequence and/or chord)
- [x] Double-tap confirmation per note
- [x] Product add service calls
- [x] Voice announcements via Assist Satellite
- [x] Basic logging and error handling
- [x] Systemd service for autostart
- [x] Test mode for offline validation
### Phase 2: Robustness (Next)

- [ ] Rate limit visualization (LED or log warnings)
- [ ] Unit tests for state machine and mapping
### Phase 3: Enhanced UX (Future)
- [ ] Web UI for live mapping editor
- [ ] MIDI learn mode (press key to assign product)
- [ ] Visual feedback on piano (if supported via MIDI out)
- [ ] Batch mode: collect multiple notes, then "submit" chord
- [ ] Undo last add (special note or chord)
- [ ] Shopping cart display on e-ink screen
- [ ] Integration with Picnic API for product search
### Phase 4: Advanced Features (Aspirational)
- [ ] Velocity-based quantity (harder press = more units)
- [ ] Sustain pedal for modifier actions
- [ ] Octave shifting for product categories
- [ ] Export shopping list to other services
- [ ] Multi-user support (different arming passwords)
- [ ] Analytics dashboard (most-played notes/products)
## Security Considerations
1. **Token Storage**: Never commit `HA_TOKEN` to version control. Use environment variables or systemd `EnvironmentFile`.
2. **Network**: Home Assistant WebSocket should be on local network or secured with TLS.
3. **Arming**: Use a non-trivial sequence (4+ notes) or chord to prevent accidental arming.
4. **Rate Limiting**: Configured limits prevent abuse or stuck keys from flooding HA.
5. **Auto-disarm**: Timeout ensures system returns to safe state if unattended.
## Contributing
When adding features or fixing bugs:
1. Update this plan document with new config options or behavior changes
2. Add logging at appropriate levels
3. Update `config/*.yaml.example` files
4. Test on Raspberry Pi with real hardware before committing
5. Document any new Home Assistant service dependencies

# Product Search Tools
This directory contains tools to search for Picnic products and manage your keyboard mappings.
## Tools Available
1. **search_web.py** - Web interface (recommended)
2. **search_products.py** - Command-line interface
## Installation
```bash
# Install the optional Picnic API dependency
pip install python-picnic-api
```
Note: PyYAML is already installed as part of the main project requirements.
Or in your virtual environment:
```bash
cd ~/DigitalPianoPicnic
source venv/bin/activate
pip install python-picnic-api
```
## Web Interface (Recommended)
The web interface provides the easiest way to search for products and configure your keyboard mappings.
### Starting the Server
```bash
# Set credentials
export PICNIC_USERNAME='your@email.com'
export PICNIC_PASSWORD='yourpassword'
# Start the web server
python3 tools/search_web.py
# Access from browser at http://localhost:8080
```
### Features
- 🔍 **Real-time search** - Type and press Enter
- 🎹 **Keyboard key selector** - Choose MIDI note number for each product
- 💾 **One-click save** - Automatically saves to `config/mapping.yaml`
- 📱 **Mobile-friendly** - Responsive design
- ✨ **Clean interface** - Modern gradient design with hover effects
### Remote Access
Run on Raspberry Pi and access from your PC:
```bash
# On the Pi
cd ~/DigitalPianoPicnic
source venv/bin/activate
export PICNIC_USERNAME='your@email.com'
export PICNIC_PASSWORD='yourpassword'
python3 tools/search_web.py
# From your PC's browser: http://raspberrypi.local:8080
```
### Custom Port
```bash
python3 tools/search_web.py --port 9000
```
## Command-Line Interface (CLI)
For scripting or terminal-only environments.
## Usage
### Option 1: Environment Variables (Recommended)
For security, store your credentials in environment variables:
```bash
export PICNIC_USERNAME='your@email.com'
export PICNIC_PASSWORD='yourpassword'
export PICNIC_COUNTRY='NL' # Optional, defaults to NL
# Search for a product
python3 tools/search_products.py "coca cola zero"
# Interactive mode
python3 tools/search_products.py --interactive
```
### Option 2: Command Line Arguments
```bash
python3 tools/search_products.py "coca cola zero" \
--username your@email.com \
--password yourpassword \
--country NL
```
### Interactive Mode
```bash
python3 tools/search_products.py --interactive
# Then type product names:
Search for: coca cola zero
Search for: bananas
Search for: quit
```
## Example Output
```
🔍 Searching for: 'coca cola zero'
============================================================
✓ Found 3 result(s):
1. Coca-Cola Zero sugar 6-pack
Product ID: s1018231
Price: €4.99 6 x 330ml
# Add to mapping.yaml:
60:
product_id: s1018231
product_name: "Coca-Cola Zero sugar 6-pack"
amount: 1
2. Coca-Cola Zero sugar 12-pack
Product ID: s1018232
Price: €8.99 12 x 330ml
# Add to mapping.yaml:
61:
product_id: s1018232
product_name: "Coca-Cola Zero sugar 12-pack"
amount: 1
```
## Quick Reference
Common products to search for:
- `coca cola zero`
- `bananas`
- `whole milk`
- `bread`
- `toilet paper`
- `kitchen roll`
- `cucumber`
- `yoghurt`
- `coffee`
## Security Note
**Do NOT commit your credentials to git!**
Use environment variables or create a `.env` file (which is in `.gitignore`):
```bash
# Create .env file
cat > .env << EOF
PICNIC_USERNAME=your@email.com
PICNIC_PASSWORD=yourpassword
PICNIC_COUNTRY=NL
EOF
# Load it
source .env
# Use the tool
python3 tools/search_products.py "bananas"
```
## Troubleshooting
### "python_picnic_api2 is not installed"
Install it:
```bash
pip install python-picnic-api
```
### "Failed to connect"
- Check your username and password
- Make sure you can login to the Picnic app/website
- Try a different country code if you're not in NL
### Search returns no results
- Try different search terms (Dutch names work best for NL)
- Make sure the product exists in your Picnic catalog
- Some products might have different names than you expect
