Aeon Labs Heavy Duty Smart Switch is a Z-Wave device that can report the wattage energy usage and KWH usage to a Z-Wave Controller (especially a gateway), it can be controlled by other Z-Wave devices to turn on/off loads, it can bear up to 40A current of resister loads. It also acts as a repeater that forward Z-Wave command messages to destination nodes 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.
