What do you need to know to install X10 home automation? You don’t need to know a whole lot to install a basic plug-in system, but more elaborate setups require additional skills. Compare your experience and your willingness to learn to the skills listed in the following sections.
Plug-in and Wireless Modules
If you can plug in a toaster or a TV and turn a couple of dials, you can install a wireless receiver and basic lamp and appliance modules. See Chapters 4 and 5, "Using X10 to Control Appliances."
If you are installing programmable lamp modules, you need to read and understand X10 code charts to send the appropriate commands for dimming and scenes (and have a controller capable of sending them). Learn more about that process in Chapter 6, "Using Timers and Advanced Remotes for X10."
Electrical Outlets and Switches
If you want to avoid hanging a module on an outlet, or if you want to add X10 control to a built-in light or appliance, you’re looking at replacing an outlet or a switch. To replace an electrical outlet or a switch without frying yourself or your home, you need to know how to
Follow a wiring diagram
Shut off power to the correct circuit
Use a voltage sensor
Determine the correct wiring to use for each connection
Figure 3.4 shows a typical high-end X10 two-way dimming and scene-capable light switch. The wires are color-coded to help you install the switch correctly.

If some of this seems like a foreign language, don’t panic! See the clear diagrams, photos, and technical help in Chapters 4 and 5.
X10 can be used to control your home’s furnace and air conditioning remotely, but this is a tougher installation job, requiring configuration and wiring of the thermostat and the X10 controller that connects your HVAC system to your X10 system (see Figure 3.5). I’ll explain how it works in Chapter 7, "Using X10 to Control HVAC Systems," but this is a task you might consider calling in a professional to handle for you.

X10 can control almost anything, from low-voltage outdoor lighting to draperies. As a consequence, the challenge of a particular project can be as simple as plugging in a couple of controllers or as difficult as decoding a logic circuit.
Computer and Internet
The ultimate in home automation is computer control—especially if you can control your home from your office via the Internet. If you’re considering moving up to computer control, you need to understand the following items:
How to connect devices to your computer’s serial or USB ports
