What is a Group?

A Group is a set of logical Links between INSTEON devices. A Link is an association
between a Controller and a Responder or Responders. Controllers originate Groups,
and Responders join Groups.
Devices in a group share all the same settings, for example on-level, ramp rates, etc.
This keeps all group members synchronized. Every device in a group is both a
controller of and responder to all other devices. The most common example of a
group is a 3-way lighting circuit with 2 switches, such as switches at either end of a
hallway.
Internally, in a Link Database maintained by INSTEON devices. A Group can have one
or many members, limited only by the memory available for the Link Database.
Examples of Groups
A device configured as a wall switch with a paddle could be designed to support one,
two, or three Groups, as shown in the following examples.
