The Crestron CLW-DIMSWEX-E-W-S is a wireless, single-channel appliance control module designed to integrate plug-in electrical devices into a Crestron automation system. It functions as a smart, in-wall replacement for a standard electrical outlet, allowing users to remotely control and schedule the power to lamps, fans, coffee makers, or other plug-in appliances. The module is installed behind a standard wall plate and includes a receptacle on its face, providing a clean, built-in appearance. Communication occurs wirelessly over Crestron's secure RF network, receiving commands from Crestron keypads, touchscreens, or automation processors to turn the connected appliance on or off based on schedules, scenes, or sensor inputs.

A key feature of this model is its energy monitoring capability (denoted by the "E"), which measures the real-time power consumption (in watts) of the connected device and reports this data back to the control system. This enables energy usage tracking, reporting, and the creation of automation rules based on power draw. The "S" indicates it includes an ambient light sensor, which can be used to trigger actions based on room brightness. The white finish ("W") ensures it blends with standard decora-style wall plates. This module is ideal for retrofitting smart control into existing spaces without running new control wires, offering a combination of convenience, energy management, and seamless integration into a whole-home or building automation ecosystem.
