Essential Info

Darkened, unoccupied homes can be irresistible to burglars. Protect your home and the valuables inside when you're away with the House Sitter Random Light Timer. Unlike timers that turn lights on and off at specific times each day, the House Sitter turns on and off randomly, with no set pattern, so your house will appear to be occupied at all times. This device will also work with a radio or television to deter would-be intruders.

What's Included

  • Timer
  • Warranty card
  • More Info

    Plug the House Sitter Random Light Timer into any standard electrical outlet. Turn the lamp or appliance on and then plug it into the House Sitter. With the switch in the "Continuous" mode, you'll be able to use your lamp or appliance normally. When you go on vacation or just out for the evening, flip the switch to the "Security" position, and the House Sitter will turn your lamp or radio on and off in intervals ranging from 9 to 34 minutes.

    MARIA, Your TV is probably a newer model that has a standby mode on all the time that the unit has power. When you press the power button on the TV or the remote, it turns on the screen immediately. The standby mode is what will come back on when the timer restores power; but if no one is there to turn the screen with the remote or TV power switch, you will not get picture or sound. Barc

    I regret that this item has been discontinued! I wished to order another. I have two already. The way in which I use them may give you an idea for another product. I use them in tandem with another timer. The first timer is the type with the female electrical connection is on the front directly in the center of the timer. This way the House Sitter Timer is facing directly out from the wall when it is plugged in. I set the first timer to those times of the day or night when I want a light on in the area. For security purposes I then use the random timer so that during that designated time there is a random display of light. By using only the single timer eventually it could be observed that there were lights on only at very specific times. By adding the random timer it varied the light but still in a specific time period. It would seem that could be combined in one unit.

    I love the item. I gave my friend a key to come into the house since i would not be home until late. While her and her husband were talking in my kitchen the radio and the light went on. They looked at each other and ask each other Did you turn that on??? they loved it and bought 2 of them...... But it does not work with the T.V. It turns it of off but it does not turn it on again.Am I doing something wrong???

    very basic a light sensor would be nice
    TERRI -- tacoma, WA   1/5/2009
    It's perfect; just wish I had a little more control over the time intervals for which the timer is set on or off

    Quote -- GRAHAM -- LAUREL, MD Date: 12/1/2007 PART #: 25505 Comment: Random times and length of time is good, but how many people get up at night and turn lines on all night. -- UnQuote It would appear that someone is not able to sleep during that period. I find it perfect for me. Yes, I agree, they are gonna be gifts.

    Great price and product, we're probably going to buy a few more and give them to our family.
    SCOTT -- tooele, UT   12/26/2007
    The only suggestion I could make would be to have an option to increase the random switching intervals; i.e., 20 minutes to 120 minutes.
    GRAHAM -- laurel, MD   12/1/2007
    Random times and length of time is good, but how many people get up at night and turn lines on all night.
    GREGORY -- fort myers, FL   11/7/2007
    I think the product could be improved by having the random lighting coming on only after dark
    ANNIE -- shreveport, LA   7/24/2007
    It is a great product. Easy to use and an inexpensive way to protect your home. Works with my lamps and radio.
