Question: How to program
Document: I returned these to Amazon - they are worthless - hard to program and if the power goes out - you will need to reprogram them each time. DO NOT PURCHASE!! !
Easy to program...VERY HANDY TO HAVE!!! And at a great price too. I bought a couple for a customer and liked them so much I purchased one for our household too. Highly recomend this product.
Difficult and inconsistent to program. Got 2 out of 3 outlets linked to remote. They stop working with each electrical glitch and must be reset. I'm not using them anymore.....it's just not worth the hassle! I'd suggest buying a simple, single outlet remote instead.
System is not intuitive to program, and then the remote broke within a couple months. Tried replacing the battery with a new (not cheap) battery and shouldn't have even wasted my money. On the 6-button remote, only the 6th button works anymore - pressing any of the other buttons doesn't even register a red light on the remote. Find another product.
I returned this item after one day. The range for one of the three outlets was only about 10 feet. Also, I was unable to program the three units to three different addresses. And to top it off, the battery in the remote control went dead within 24 hours! At the very least there are some quality control issues with these units.
Must be reprogrammed after every power interruption. Yet one must program them individually or they all end up the same i.e. the last one programmed. So you must unplug the other two each time you program a third one...but each time you unplug any of them...they lose their programming...(Scream! )According to the Reviews, many experience a cheap devise that soon breaks.
Right out of the box, these work great. Then after 1-2 weeks they stop working and you have to re-program them (not talking about power outages). Then after doing this a couple times, they just stop working. I have two sets of these since I thought they were a great deal, and neither of my sets will work any longer.I had one receiver/outlet get very hot, even while in the off position.
Totally worth it.Hint:  read the instructions, though! At first, all were controlled by one switch - because I plugged them all in before I did first programming. Plug in one, program, then the next, and finally the last. Of course, if they're all on one signal, you can turn all on and off with one button - but I like being able to just turn on one or two instead of all 3 at one time.
So the item comes with three receivers (that plug into your wall) and one remote control. On the upside, it is very simple to set up/program. You just plug the receiver into your wall and a little red light starts flashing. When you see that, you just push the button on the remote so the receive can "learn" the remote's signal. You can control all three receivers from the one remote...allegedly. I set up the first two without incident.
This worked great for a while, and it is great it's exapndable to some extent and being able to program multiple receivers to each button on the remote, but after a while, the buttons on the remote are no longer responsive to the point the remote becomes worthless. I have 3 sets, a bunch of working receivers left, but only 1 remote still works out of the 3, and even that one only 2 of the 3 buttons work, and even that one button is sometimes sketchy.
Answer: yes
