The Aeon Labs Inline Smart Energy Illuminator is a Z-Wave light dimmer specifically used to enable Z-Wave command and control (on/off/dim) that is connected to a standard Wall Outlet. It can also report immediate wattage consumption or kWh energy usage over a period of time. The wireless module is powered from the mains supply and is a three-wire design which requires a neutral connection. In the event of power failure, non-volatile memory retains all programmed information relating to the units operating status.
