The Aquascape Smart Control Hub is required to run and control Aquascape colour-changing lights, controlling your lights from anywhere with your smartphone or tablet using the Aquascape Smart Control App. The hub is capable of a variety of lighting functions, such as colour selection, cycle, dimming, colour themes, and dynamic scheduling. The astronomical timer function allows lights to be turned on and off automatically based on your location. Integrated, weather-proof, quick-connect fittings make setup quick and easy, simply plug in your lights, pair the hub to your device, and enjoy. Create lighting zones or control separate sets of lights simultaneously by using multiple hubs, further expanding the variety of lighting options. Each hub can control up to 150 watts of Aquascape colour-changing lights and a 12-Volt transformer is required to power the Smart Control Hub and lights. Use Aquascape colour-changing splitters and extension cables to connect multiple lights to one hub. An optional Colour-Changing Lighting Remote (Item #84073) is available separately, allowing for wireless control without the use of a smartphone or tablet. Note: The Smart Control Hub is only compatible with Aquascape colour-changing lights. The Smart Control Hub is compatible with iPhone and Android operating systems and adequate wireless coverage is required (2.4 GHz supported). The Smart Control Hub is backed by a 5-year limited warranty to ensure years of reliable use.
