The US2TP11 is a pre-configured, 4-button, version of the US28XTP table top controller designed to work with the SimplySmart line of pre-configured devices.
The Tabletop Controller, model US28XTP, remotely controls the operation of Universal Powerline Bus (UPB) devices over the power wiring. Pressing buttons on the controller sends command signals to other UPB devices, such as lamp and appliance modules and UPB wall switches. Controllers and modules can be freely located anywhere in the home. No additional wiring is required and no radio frequency signals are used.
Note: With the SimplySmart pre-configured devices, each device has been hard coded with a unique ID, which means you'll only want one of each of the following in a single home: DKIT-02, DKIT-02, UML7, UML8, US1W9, US1W10, US2TP11, or US2W12. Having more than one of these in the home will make communication unstable, as these are designed to be starter devices only.
