Level 2 – Macros
Level 2 adds a “macro” capability. A macro is the ability to use one command to actually control several devices. A single touch could dim the lights, close the drapes, put on soft music and start the Hot Tub. One macro can actually run another macro as well. Some type of programming is required to store the macros. This programming can be done from another controller or from a computer. These devices are in fact sophisticated controllers that do not require a computer to run normally. Level 2 control has an intermediate piece of hardware or software.

Examples of Macro Controllers
The macro controller might also have a built in timer, so it can initiate commands by itself. For example, it might turn on and off lights at a certain time of day. More sophisticated level 2 controllers, include the knowledge of the date and even the time of sunrise and sunset.
