Control lights or small appliances that are plugged into this duplex outlet module. It replaces any standard duplex module and includes one "always-on" outlet that is not controlled by Z-Wave. The other outlet can be added to your wireless Z-Wave network and controlled by your scene controller or other remote control. Wall plate not included. Installing in-wall modules can be severely dangerous; we strongly recommend using a licensed electrician to install in-wall outlets and switches.
