Active Home Vista is the ´control centre´ of your home automation system. You can control all your devices, program the CM11A and receive updates from the CM11A to see what’s going on X10-wise. You’ll need a computer, a free serial port and the CM11A to do anything useful. Dusk & dawn timers are supported. The limited Eeprom of the interface is used in an efficient way to store as many timers & macros as possible. Also DST support is present.
