Find Other Computers
The Find Other Computers feature shows which X10 addresses you are
using, and which ones are being used by another system.
The window shows you a grid of all the X10 addresses, and marks
the ones that have activity. Green marks indicate addresses used by
the current ActiveHome Pro file. Red boxes show you other
addresses where command activity has happened. Yellow boxes are
places where there might be activity that's not part of your
ActiveHome Pro setup.
If you hover your mouse over a green spot, you'll see the module
name and the last time a command was sent or received for that
module.

You can also hover over read boxes to see when commands were
received for those addresses.
Understanding House and Unit Codes
All X10 modules use an address system to allow you to control each
module separately. An X10 address consists of two parts: the House Code
and the Unit Code.
House Codes
A House Code is the part of the X10 address the assigns a module to a
group. While ActiveHome Pro can control modules set to any House Code,
other X10 remotes and controllers can only send commands to one House
Code at a time. You set the House Code of a module using the letter dial on
the module, with settings from A to P.
You can use House Codes in many different ways. If you have a number of
modules, you might want to use one House Code per room. You could also
assign House Codes based on the way you use modules. In ActiveHome
Pro in can be useful to set aside a particular House Code (M, for example)
to use only for Macro Triggers.
Unit Codes
The Unit Code of a module makes it possible to control it separately from
other modules. When you set the number dial on a module (from 1 to 16),
you should make sure you use a different number than others set to the
same House Code.
