# ThermoPro CYD Frontend

A Progressive Web App (PWA) that consumes the CYD ThermoPro Bridge API, stores session history in SQLite, and displays probe temperatures with charts, target setpoints, and freeform notes.

## Architecture

```
LXC/container
├── Python backend (FastAPI/Flask)
│   ├── Polls CYD /api/latest periodically
│   ├── Stores readings + sessions + notes in SQLite
│   └── Serves the static PWA and API
└── PWA (HTML/CSS/JS)
    ├── Dashboard with probe cards
    ├── Temperature history charts
    ├── Target setpoint editor
    └── Session notes
```

## Requirements

- Python 3.10+
- `flask`, `requests`, `gunicorn` (or `uvicorn` if FastAPI)
- SQLite (stdlib)

## Running locally

```bash
cd frontend
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -r requirements.txt
python app.py
```

Then open `http://localhost:5000`.

## Configuration

The backend needs to know the CYD IP. Set the environment variable:

```bash
export CYD_BASE_URL=http://192.168.2.55
```

or edit the default in `config.py`.

## Deployment

Serve the app behind a reverse proxy (e.g. Caddy or Nginx) in an LXC. The backend will continue polling the CYD as long as it can reach the device.
