# qr

QR-code webpage intended to be hosted at:

```text
192.168.0.226:/var/www/html/qr
```

Open QR codes with:

```text
http://192.168.0.226/qr?what=wifi
http://192.168.0.226/qr?what=haguest
```

If `what` is not defined in `what.json`, the page returns `404 Not Found`.

## QR data

Copy the example on the web server:

```bash
cp what.example.json what.json
```

Edit `what.json` on the server. It is ignored by git and excluded from deploys because it may contain secrets like Wi-Fi passwords.

Supported entries:

```json
{
  "wifi": {
    "type": "wifi",
    "label": "Home Wi-Fi",
    "ssid": "Your WiFi name",
    "password": "Your WiFi password",
    "security": "WPA",
    "hidden": false
  },
  "haguest": {
    "type": "url",
    "label": "HA Guest",
    "url": "http://192.168.0.226/haguest"
  }
}
```

The key name, such as `wifi` or `haguest`, is shown in the centre of the QR code.

## Deploy

```bash
./deploy.sh
```

The deployment helper uses `rsync` and can be overridden with:

- `QR_DEPLOY_HOST` (default: `192.168.0.226`)
- `QR_DEPLOY_DEST` (default: `/var/www/html/qr`)
