Up to 500 EyeNut devices can be managed from a single gateway, via a robust, secure ZigBee wireless mesh network. There is no limit to the number of gateways, and therefore the number of devices which can be managed by the central cloud hosted hub, which is also capable of controlling multiple sites and supporting access from multiple users.


Luminaires can easily be EyeNut enabled by connecting a simple adaptor to existing DALI or analogue control gear across a wide variety of lighting technologies. Many LED luminaires can use Harvard’s Eyenut-enabled LED drivers which convert wireless ZigBee messages into a dimmable LED drive current in a single unit.


Switches, sensors and other control devices that conform to the ZigBee Home and Building Automation profile can be used in EyeNut. Harvard’s own EyeNut sensor allows occupancy (presence and absence) and daylight and corridor linking functions to be easily applied to EyeNut enabled luminaires.


The EyeNut software, which can be accessed via a computer, laptop or tablet, allows users to commission and map their lighting. Users can visualise energy consumption, operating history and luminaire status via a sophisticated suite of reports using data from metering chips inside the EyeNut hardware.


Continual developments in functionality means that EyeNut continues to be at the forefront of the Internet of Things (IOT) enabled wireless control & management solutions for interior and exterior lighting. Latest developments include emergency testing, outdoor lighting control and BeMS integration.
