The E27 lamp from Ledvance Smart + is equipped with modern Bluetooth technology, thanks to which the lamp can be controlled via app or voice. Thus, any conventional lamp can be retrofitted with the bulb for smart control. Simply replace the conventional bulb with the filament lamp, connect with the appropriate app and start. Expensive additional devices, such as a bridge or a gateway, are not necessary here. The Ledvance Smart + Bluetooth technology is suitable for Android and iOS. To control the lamps and luminaires, the matching Ledvance Smart + app for Android or the Apple Home app for iOS is downloaded and you can get started. The integration of the voice assistant Alexa (Android) or Siri (iOS) is easily possible with the respective app and enables, for example, dimming by voice command.
