The Aeotec Micro Smart Energy Switch G2 is a low-cost Z-Wave appliance module specifically used to enable Z-Wave command and control onoff for existing in-wall switches. 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. It also is a repeater in the Z-Wave network. Acting as a bridge for communication it will forward Z-Wave command messages to their destinations if the originating controller is out of range from the destination node. By taking advantage of the Z-Wave mesh network commands can be routed to their destination via intermediary listening Z-Wave products. Products that are Z-Wave certified can be used and communicate with other Z-Wave certified devices. . For Use with HomeSeer and Other Z-Wave Automation Systems.
