Essential Info

The Intermatic EJ500C 24-Hour Electronic In-Wall Timer is a replacement for your standard indoor wall switch which includes an optional Self-Adjusting feature that automatically changes with the daily sunrise and sunset. This in-wall timer provides seven on/off times and is available for all seven days of the week. In addition, the timer can be adjusted for the weekdays without affecting the weekend time schedule. The included randomization feature will make sure the lights do not turn on at exactly the same time every day which increase the security of your home by deterring possible burglars. At any time, the lights can be overridden to turn on and off without interrupting the current set schedule.

    I have two of these installed. They worked great for the first six months or so, then both of them stopped working. I've reset the programming multiple times trying to get them functioning again but to no avail. They are now just large and expensive manual on/off switches.
    MARLIN -- plainwell, MI   3/1/2013
    The screen is so tiny, I can't read all lines even using a magnifying glass! That makes programming it impossible for me.
    GEORGE -- liberty twp, OH   5/28/2012
    The first unit was defective but the customer service rep sent a second unit free of charge based on my phone conversation. No return on the bad unit was required. The second unit has been functioning well for over 2 weeks. I am extremely pleased with the way the whole order was handled.
    GEORGE -- liberty twp, OH   4/30/2012
    Timer arrived on time. Installation was easy. Unit started to malfunction after 3 days. Batteries went dead. Replaced with new but they went dead in 2 days. Smarthome sent replacement which was installed today. Will have to see if this one lasts longer.
    MR TOM -- poquoson, VA   4/19/2012
    Excellent delivery time
    JAIME L -- arlington heights, IL   4/12/2012
    These timers work great. The lights come on at sunset each night and off at the programmed time.
    STUART -- swannanoa, NC   4/5/2012
    This is an excellent product, it does everything I wanted.
    Jose Gutierrez -- caracas, Venezuela   3/11/2012
    I spend several days tryng to set the hour to on/off; I live in Venezuela y would like if somebody ncan tell me how can I put just that times, no the sunset or the sunrise and other complication like the zone; I would like to put the year, the month and day and the hour to on and to off, just that one; it is possible that thing? Regards
    BRIAN -- melbourne, FL   3/9/2012
    Works great. Arrived quickly and installed easily.
    JIM -- freehold, NJ   3/3/2012
    Works well and was easy to install except very large to fit into a box with a lot of wires and wire nuts
    JOHN -- needham, MA   2/26/2012
    Good product but it took over 2 weeks to arrive
    I A -- alta loma, CA   2/23/2012
    Easy installation. Programming easy too.
    PAUL -- crestwood, IL   2/23/2012
    LOUIS -- birmingham, AL   2/6/2012
    I had one before so i knew how good they are.
    PATTI -- mobile, AL   2/3/2012
    I purchased this because I wanted my porch light to stay on all night and me not forget to turn it off the next morning! Well, it works great! It was easy to install and the set up was a breeze. The only drawback is the small buttons and the hard to read tiny print, but I think that's more to do with my age than the product itself. LOL If you are looking for a great 24-hour timer, then I would highly recommend going with this one. And Smarthome service was fast!!
    JEREMIAH -- alamogordo, NM   1/29/2012
    Works great! Instructions covered all situations. The only improvement would be a backlit LCD to help in setting up. After I installed it I haven't touched it. Should be installed by someone with decent knowledge of electrical wiring if using a 3 way switch.
    GREG -- cartersville, GA   1/12/2012
    Super easy to install and easy to program. Works great, best buy for the money and a higher rated product than what was available at my local big box home improvement stores.
    MARY ANN -- louisville, OH   12/27/2011
    great timer for the price. easy install. screen was a little hard to read for us old people.
    GERALD -- alden, MI   12/12/2011
    I cannot give a good rating to a device which causes my electric meter to run when not in use. When off and there's a load attached, this switch continues to draw power which cannot be good for the switch, load or my wallet.
    DAVE -- kansas city, MO   11/3/2011
    Great service, great price, great products
