The ABB Busch-Jaeger Friends of Hue light switch allows for the convenient control of your Philips Hue lighting system with just the press of a button. This smart switch is capable of switching and dimming Philips Hue lights, and can store, recall, and dim up to 2 individual light scenes. The switch operates on radio frequency at 2400MHz. It features unique 'Energy Harvesting' technology, generating enough energy to send a wireless signal to your Hue lighting whenever a button is pressed. This means the switch is battery-free and maintenance-free. It is easy to install and can be placed anywhere, without the need for wiring. It requires a second generation Philips Hue Bridge and Philips-Hue-app (version 3.2 or higher) for wireless operation. The set includes the smart switch base, a 2-operation rocker, a single glossy traffic white frame, a mounting plate, spacer plate, and decorative sticker.
