The easiest to use (and install) home automation device is the plug-in module. These devices most commonly control plug-in lamps, but they can control virtually any gadget you can plug into an electrical outlet.
Installing Plug-In Modules
A key advantage of plug-in modules is that no wiring or special installation is required. Simply plug the module into an outlet, plug the device you want to control into the module, and then link the module to a controller. Plug-in modules are ideal for anyone intimidated by installing hard-wired automated light switches. They can also serve as an alternative solution for homes that don't have neutral wires installed in the switchboxes.
Types of Plug-In Modules
Plug-in modules were one of the first types of home automation devices. They are available for each popular automation standard (Insteon, X10, Z-Wave). Because they are one of the most inexpensive devices available, plug-in modules often chosen by new home automation enthusiasts getting started with their network.
Unlike ordinary home lights that can be dimmed, some devices like florescent lights, fans, or radios operate in only two modes - "on" and "off." Appliance modules provide strictly on/off control, allowing you to manage devices that shouldn't be controlled with dimmers. Make sure to choose a plug-in module specifically designed for on/off appliances in these cases.
