This ZWN-323 Dimming Module is a Z-Wave enabled device and is fully interoperable with other Z-Wave certified device. In a Z-Wave network, ZWN-323M enable you to remotely ON/OFF&Dim control a Z-Wave controlled outlet for the lamp and always-on AC outlet for other device. ZWN-323M also acts as a repeater, retransmitting the RF signal from one device to another until the intended device is reached. With a horizontal design, the ZWN-323M plug-in dimmer module will not block other nearby AC outlets. The ZWN-323M Smart Meter Module enables you to measure the energy usage of your appliance. When added to a Z-Wave network, the Smart Meter Module reports real time data to your gateway or controller. It can also display actual consumption (in W) and the accumulated power used (in kWh) in the user interface of the gateway/remote. Please use the gateway installation manual for specific instructions on measuring the module.
