[![verified-by-homebridge](https://badgen.net/badge/homebridge/verified/purple)](https://github.com/homebridge/homebridge/wiki/Verified-Plugins)

A lightweight Homebridge plugin that creates occupancy sensors based on UniFi device presence detection. Track residents by their devices and create room-specific presence sensors.

## Features

🏠 **Resident-Based Tracking** - Configure residents with their specific devices  
📱 **Multi-Device Support** - Each resident can have multiple devices (phone, laptop, tablet, etc.)  
🌐 **Global Presence Sensor** - Single sensor showing if anyone is home  
📍 **Room-Specific Sensors** - Individual sensors for each WiFi access point/room  
🔌 **Dual API Support** - Works with local UniFi controllers and cloud Site Manager API  
📊 **Traffic Monitoring** - Optional minimum traffic thresholds to detect active usage  
⚡ **Lightweight** - Minimal resource usage, API token authentication only  

## Supported UniFi Devices

- UDM Pro / UDM Pro SE / UDM Pro Max
- UDM / UDM SE
- UDR (UniFi Dream Router)
- UCK-G2-PLUS (CloudKey Gen2 Plus)

## Getting Your API Key

### Local Controller API Key

1. Open your UniFi Network Controller web interface
2. Go to **Settings** → **System** → **API**
3. Enable "Enable API" if not already enabled
4. Create a new API token or use existing one
5. Copy the API key for your configuration

### Site Manager API Key (Cloud)

1. Log in to [UniFi Cloud Console](https://unifi.ui.com)
2. Go to **Account** → **API Tokens**
3. Create a new token with appropriate permissions
4. Set `useSiteManagerApi: true` and provide your `hostId`

## Configuration Options

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `unifi.controller` | string | **required** | URL of your UniFi controller |
| `unifi.apiKey` | string | **required** | API key from UniFi Network settings |
| `unifi.useSiteManagerApi` | boolean | `false` | Use Site Manager API instead of local controller |
| `unifi.hostId` | string | - | Host ID for Site Manager API (required when using cloud API) |
| `unifi.site` | string | `"default"` | UniFi site name |
| `unifi.secure` | boolean | `false` | Enable SSL certificate validation |
| `interval` | number | `180` | Refresh interval in seconds (30-3600) |
| `globalPresenceSensor` | boolean | `true` | Create global presence sensor |
| `residents` | array | `[]` | List of residents and their devices |
| `wifiPoints` | array | `[]` | List of WiFi access points for room sensors |

### Resident Configuration

| Option | Type | Description |
|--------|------|-------------|
| `name` | string | Display name for the resident |
| `devices` | array | List of devices belonging to this resident |

### Device Configuration

| Option | Type | Description |
|--------|------|-------------|
| `name` | string | Display name for the device |
| `mac` | string | MAC address of the device (most reliable) |
| `ip` | string | IP address of the device |
| `hostname` | string | Hostname of the device |
| `minTrafficAmount` | number | Minimum traffic in KB over 15 minutes to consider device active |

### WiFi Point Configuration

| Option | Type | Description |
|--------|------|-------------|
| `name` | string | Room/location name for the sensor |
| `mac` | string | MAC address of the access point |
| `ip` | string | IP address of the access point |

## Device Identification

The plugin identifies devices using the following priority:

1. **MAC Address** - Most reliable, matches exact device
2. **IP Address** - Good for devices with static IPs
3. **Hostname** - Useful for named devices

If multiple identifiers are provided, ALL must match for positive identification.

## Traffic Monitoring

Set `minTrafficAmount` (in KB per 15 minutes) to ensure devices are actively being used:

- **Unset/0**: Any connection counts as presence
- **50-100 KB**: Light activity (notifications, background sync)
- **500+ KB**: Active usage (browsing, streaming)

*Note: Traffic monitoring only works with local controller API, not Site Manager API.*

## HomeKit Integration

The plugin creates the following accessories in HomeKit:

- **Global Presence** - Occupancy sensor showing if any resident is home
- **[Room Name] Presence** - Occupancy sensor for each configured WiFi point

These appear as standard occupancy sensors and can be used in HomeKit automations.

## Automation Examples

### Welcome Home Automation
```
When: Global Presence detects occupancy
Action: Turn on lights, adjust thermostat, disarm security
```

### Room-Based Lighting
```
When: Living Room Presence detects occupancy
Action: Turn on living room lights
When: Living Room Presence detects no occupancy (after 5 minutes)
Action: Turn off living room lights
```

### Security Integration
```
When: Global Presence detects no occupancy (after 30 minutes)
Action: Arm security system, set away mode
```

## Troubleshooting

### No Devices Detected
- Verify MAC addresses in UniFi controller match configuration
- Check that devices are connected to WiFi (not ethernet)
- Ensure API key has proper permissions

### Site Manager API Issues
- Verify Host ID is correct
- Check API key permissions in UniFi Cloud Console
- Ensure `useSiteManagerApi` is set to `true`

### WiFi Points Not Working
- Verify access point MAC addresses or IP addresses
- Check that access points are online and managed
- Ensure access point naming is consistent

### Traffic Monitoring Not Working
- Feature only available with local controller API
- Check that controller firmware supports traffic statistics
- Reduce `minTrafficAmount` threshold for testing

## API Compatibility

| Feature | Local Controller | Site Manager API |
|---------|------------------|-------------------|
| Device presence detection | ✅ | ✅ |
| Traffic monitoring | ✅ | ❌ |
| WiFi point identification | ✅ | ✅ |
| Real-time updates | ✅ | ✅ |
