12.2 Helpful Information on INSTEON and ISY
45
First off, some nomenclature. Every Insteon device has an address - in the format aa.bb.cc
where the letters correspond to Hex number 0-F. This system allows for over 16 million
different addresses and I doubt Smarthome has sold that many devices but at some point
they will repeat. It is important, though, that every device in your home have a unique
address.
Next - Insteon deals in 'groups'. Every kind of command in Insteon is a group command. As
such the words related to Insteon are heavily flavored with the word group. Insteon also
deals with 'controllers' - devices that send group commands such as on or off and
'responders' - devices that receive these group commands and act accordingly. Some
devices are both controllers AND responders - such as KeypadLincs or SwitchLincs. Some
are just controllers - like Motion Sensors - and some are just responders - like InlineLincs.
Regardless the terminology is the same.
In the context of a device as a controller the buttons on that device are not referred to as
buttons. They are referred to as groups. A SwitchLinc has, therefore, 1 group - its paddle.
We'll call this group 1. KeypadLincs can have either 8 groups or 5 (the on/off on a KPL6 is
group 1). When they have 8 groups they're simply referred to as groups 1-8. When there
are 5 groups they are referred to as groups 1,3,4,5,6
In the context of a device as a responder the buttons are referred to as buttons - and the
numbering is the same as the groups are for controllers.
If it helps, you can think of the part that clicks when pressed as the groups and the LED's
that light up on them as the buttons.
