# Configuration API Documentation

The configuration API allows you to read and modify the `tellstick.conf` file through REST endpoints.

## Endpoints

GET /api/config
```
Returns the complete configuration including global settings, controllers, and devices.

**Response:**
```json
{
  "user": "root",

Returns an array of all devices defined in the configuration file.

**Response:**
```json
[

## Device Parameters

Common parameters for different protocols:

### Arctech (selflearning-switch, selflearning-dimmer)

{
  "house": "12345678",
  "unit": "1"
}
```

### Nexa (codeswitch, bell)

## Notes

- Changes to the configuration file will trigger an automatic daemon restart and device reload
- The config file watcher will detect changes and sync devices/sensors automatically
- Device IDs in the config file are separate from runtime device IDs
- All modifications are written immediately to `/etc/tellstick.conf`

## Example Usage

### JavaScript/Fetch
```javascript
// Get all config devices
const devices = await fetch('/api/config/devices').then(r => r.json());

// Create a new device
const newDevice = await fetch('/api/config/devices', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    name: 'Living Room Light',
    protocol: 'arctech',
    model: 'selflearning-switch',
    parameters: {
      house: '12345678',
      unit: '3'
    }
  })
}).then(r => r.json());

// Update device
await fetch(`/api/config/devices/${newDevice.id}`, {
  method: 'PUT',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    name: 'Living Room Lamp',
    protocol: 'arctech',
    model: 'selflearning-switch',
    parameters: {
      house: '12345678',
      unit: '3'
    }
  })
});

// Delete device
await fetch(`/api/config/devices/${newDevice.id}`, {
  method: 'DELETE'
});
```
