# Zigbee & Zigbee2MQTT Integration

**Meta-Description:** Zigbee Smart Home mit Zigbee2MQTT. Lokale Kontrolle, MQTT Bridge, Device Pairing und Home Assistant Integration.

**Keywords:** Zigbee, Zigbee2MQTT, Smart Home, MQTT, Home Assistant, Local Control, Mesh Network

---

## Einführung

**Zigbee** ist das bewährte Protokoll für batteriebetriebene Smart Home Geräte. **Zigbee2MQTT** macht es unabhängig von proprietären Bridges – lokale Kontrolle via MQTT mit über 4.000 unterstützten Geräten.

import express from 'express';
import { Zigbee2MQTTClient } from '../lib/zigbee2mqtt-client';

const router = express.Router();
const z2m = new Zigbee2MQTTClient(process.env.MQTT_URL || 'mqtt://localhost:1883');

// GET /api/devices
router.get('/devices', (req, res) => {
  const devices = z2m.getDevices()
    .filter(d => d.type !== 'Coordinator')
    .map(d => ({

  res.json(devices);
});

// GET /api/devices/:name

## Device Groups

```yaml
# configuration.yaml

groups:
  living_room:
    friendly_name: Wohnzimmer
    devices:
      - living_room_light_1
      - living_room_light_2
      - living_room_light_3

      - kitchen_light
```

```typescript
// Gruppen steuern
z2m.setState('living_room', { state: 'ON', brightness: 200 });

// Alle Lichter aus
z2m.turnOff('all_lights');
```

---

## Scenes & Automations

```yaml
# configuration.yaml

# Szenen definieren
scenes:
  - name: movie_mode
    data:
      living_room:
        state: 'ON'
        brightness: 50
        color_temp: 500
      kitchen:
        state: 'OFF'

  - name: morning_routine
    data:
      bedroom_light:
        state: 'ON'
        brightness: 100
        color_temp: 250
```

```typescript
// Szene aktivieren
z2m.publish('scene/recall', { scene: 'movie_mode' });

// Custom Automation
z2m.onStateChange('motion_sensor', (state) => {
  if (state.occupancy) {
    z2m.turnOn('hallway_light');

    // Auto-Off nach 5 Minuten
    setTimeout(() => {
      const currentState = z2m.getState('motion_sensor');
      if (!currentState?.occupancy) {
        z2m.turnOff('hallway_light');
      }
    }, 5 * 60 * 1000);
  }
});

// Temperature-basierte Automation
z2m.onStateChange('temperature_sensor', (state) => {
  if (state.temperature && state.temperature > 25) {
    z2m.publish('fan/set', { state: 'ON', preset_mode: 'high' });
  }
});
```

## Zigbee Network Map

```typescript
// Network Topology abrufen

// zigbee2mqtt/bridge/request/networkmap
z2m.publish('bridge/request/networkmap', { type: 'raw' });

// Antwort auf zigbee2mqtt/bridge/response/networkmap
interface NetworkMap {
  nodes: Array<{
    ieee_address: string;
    friendly_name: string;
    type: 'Coordinator' | 'Router' | 'EndDevice';
    network_address: number;
    lqi: number;  // Link Quality Indicator
    relationship: number;
  }>;
  links: Array<{
    source: { ieee_address: string };
    target: { ieee_address: string };
    lqi: number;
    depth: number;
  }>;
}
```

---

## Troubleshooting

```typescript
// Häufige Probleme und Lösungen

// 1. Gerät reagiert nicht
async function troubleshootDevice(deviceName: string) {
  const state = z2m.getState(deviceName);

  // Linkqualität prüfen
  if (state?.linkquality && state.linkquality < 50) {
    console.log('Low link quality - consider adding router devices');
  }

  // Availability prüfen
  // Subscribe to zigbee2mqtt/[device]/availability

  // Device Interview neu durchführen
  z2m.publish('bridge/request/device/interview', { id: deviceName });
}

// 2. Pairing funktioniert nicht
function resetAndPair() {
  // Permit Join aktivieren
  z2m.permitJoin(true, 180);  // 3 Minuten

  // Gerät in Pairing-Modus versetzen (geräteabhängig)
  console.log('Reset device and put in pairing mode');
}

// 3. Mesh-Netzwerk optimieren
function optimizeMesh() {
  // Router-Geräte (Steckdosen, Lampen) sind wichtig für Mesh
  // Mindestens ein Router pro Raum

  const devices = z2m.getDevices();
  const routers = devices.filter(d => d.type === 'Router');
  const endDevices = devices.filter(d => d.type === 'EndDevice');

  console.log(`Routers: ${routers.length}, End Devices: ${endDevices.length}`);

  if (endDevices.length / routers.length > 6) {
    console.log('Warning: Not enough routers for stable mesh');
  }
}
```

## Fazit

Zigbee2MQTT bietet:

1. **Lokale Kontrolle**: Keine Cloud-Abhängigkeit
2. **4000+ Geräte**: Herstellerunabhängig
3. **MQTT Integration**: Einfache Anbindung
4. **Open Source**: Aktive Community

Der beste Weg für ein offenes Smart Home.
