2. Smart Home System Integration
The OSRAM Smart+ bulb uses ZigBee for smart home connectivity.
- Direct Compatibility with Echo Plus: The bulb is directly compatible with Amazon Echo Plus. To pair, ensure your Echo Plus is powered on and in setup mode, then power on the bulb. The Echo Plus should detect and connect to the bulb automatically.
- Compatibility with Amazon Echo (via Gateway): For other Amazon Echo devices, a compatible ZigBee gateway (e.g., OSRAM Lightify Gateway or other ZigBee-enabled gateways) is required. Connect the bulb to your gateway according to the gateway's instructions, then link the gateway to your Amazon Echo device.
- Lightify App Setup: For control via the Lightify app, download the app (available for Apple iOS 7 and Android 4.1 or above). Follow the in-app instructions to add your bulb to the system. This typically involves ensuring the bulb is powered on and initiating a search for new devices within the app.
