I have 2 RF jumpers, 8 switches, one keypad switch, 2 plug in modules, one low voltage controller, and a usb interface. Its addictive. My insteon project started simply to fix a couple odd light switch placements. Then I figured I could simple wire the garage door to trigger the lights to come on. then consolidate all the outside lights and applied timers. Lastly I wired (3) blind motors to a plug in module and wall switch. It automatically puts the blinds down at night in the winter and in the afternoon in the summer. Im sure it will pay for it self in 50 years (or less if oil keeps going like it has)...Overall I am very happy with the insteon products except for the high price. Sometimes you can catch it 20% off.
