If you use X10-compatible switches, module and controllers to automate your lighting and appliances throughout your home, adding this simple device to your setup will allow you to set up timed events easily. Using the 64-Event X10 Mini Timer will allow you to turn your lights on and off and dim them remotely as well as letting you easily setup timed events. The timer plugs into any AC outlet in your home and transmits digitally encoded signals over your house wiring instantly or at the times you set. You'll be able to schedule up to eight lights or appliances to turn on and off automatically. Have outside lights as well as inside lights and appliances go on and off at preset times so you walk into a dark home at night. Or give your home a lived-in look while you are away using a security mode that turns lights on and off at random times within a certain time frame. You can even wake up in the morning to light and sound. X10 switches or plug-in modules are required if you wish to control lights and appliances, and are sold separately. This product requires two AA batteries, sold separately.
