## Running

```bash
source venv/bin/activate
python -m rf_mapper start        # Start web server (background)
python -m rf_mapper status       # Check if running
python -m rf_mapper stop         # Stop server
python -m rf_mapper restart      # Restart server
python -m rf_mapper scan -l room # CLI scan
python -m rf_mapper --help       # All commands
```

## Deployment

See [INVENTORY.md](INVENTORY.md) for multi-node deployment details.

```bash
# Update and restart all nodes
cd ~/git/rf-mapper && source venv/bin/activate && git pull && python -m rf_mapper restart
ssh grokbox "cd ~/git/rf-mapper && source venv/bin/activate && git pull && python -m rf_mapper restart"
ssh jellystar "cd ~/git/rf-mapper && source venv/bin/activate && git pull && python -m rf_mapper restart"
```

## Tech Stack

- Python 3.10+, Flask, PyYAML, requests, bleak
- Leaflet.js (2D maps), MapLibre GL JS (3D maps)
- Linux tools: `iw`, bleak (BLE via D-Bus)
- SQLite for device history
- Home Assistant webhooks for integration
