Know the X10 Address

To send commands to X10 devices, you need to know their addresses. Here are the basics of deciding which addresses to use and how to set them.

The X10 protocol works by sending commands—using the power line in your home—to modules that know how to listen for and respond to requests to turn on, turn off, or brighten the lamp or appliance which they’re controlling. A lot of careful timing and engineering are involved to send and receive the commands, but all you really need to know is that each module understands which commands to react to and which ones to ignore.

Here’s how it works. Unlike the Postal Service, which (hopefully) delivers mail directly to your address, X10 crudely broadcasts its commands far and wide, throughout your entire electrical system. It’s up to each module to continuously listen for commands and discern whether each one is meant for it. To facilitate this, every X10 command is prefaced by an address. If the command’s address matches that of the module, the module acts on the command; otherwise, it ignores it and waits to see if the next command is meant for it instead.
