Unfortunately, people rarely notice a dangerous rise in temperature in the freezer until it's too late, letting that freezer full of food go to waste! The Freezer Watchdog provides a way to sense inordinately high temperatures or the early failure of a residential freezer. Simply place the sensor in your freezer and carefully extend the wire leads out the freezer door through the freezer's weather stripping and attach the wire leads to an X10 Powerflash module. From there, you can have the Powerflash module send out X10 commands to other X10 controlled devices such as an X10 Lamp Module or an X10 Appliance Module to turn lights on in the event that the freezer's temperature rises to an unacceptable level. The new Freezer Watchdog has a power transformer, automatic reset circuitry and better temperature sensitivity to ensure you'll receive an instant notification via X10 so you'll be able to begin rectifying the situation if your freezer fails.
