DEWENWILS Wireless Light Switch and Receiver Kit, No in-Wall Wiring Required, Remote Control Switch Lighting Fixture for Ceiling Lights, Fans, Lamps,100 Ft RF Range, Programmable

It works great! I used it to remotely control a light/ceiling fan combination in my living room. The house is not wired for separate control of those things. I damaged my sense of balance from a fall and I'm not able to climb a ladder to install a device designed specifically designed for this purpose. I installed the receiver inside the electrical box in place of the wall switch. I stuck the transmitter onto a plastic "blank" cover plate mounted where the original switch was. I use that for local control and I paired a second transmitter for remote control. Pairing is extremely easy and you can control a device with multiple transmitters or multiple receivers. It works well in spite of the fact that the box is metal. I put a 3M thrust bumper on the receiver near the on/off/pair button to keep it from being accidentally pushed by the cover plate. You can of course pull the remote off the cover plate to use it remotely if you like, because I used 3M Command Strips which are similar to Velcro to mount the remote control onto the cover plate. EDIT 1: I bought another pair of these to use in my bedroom but the receiver would not work as well as the one in the living room. I tried all of my transmitters, since the receiver is very easy to pair to different transmitters. The electrical box in my living room is metal, but the one in my bedroom is plastic. I also tried all three of the extra receivers I had, with no improvement. EDIT 2: It turned out to be a "ground loop" issue. The thing has two " Neutral" wires connected together inside the receiver. Cut one of them off. Do not connect both of them to the same point. At this high frequency, the signal from the remote causes 433 MHz current to circulate through the two ground wires, producing a "ghost" signal out of phase with the original signal from the remote, cancelling some of it out, causing unreliable operation. The metal electrical box of the one in the living room prevented the ground loop from causing a problem. In the bedroom unit, fixing the ground loop helped, but it did not completely fix the problem. EDIT 3: Multi-path interference. The first setup I did in my living room was perfect in every way, but I had a lot of trouble with the second setup in my bedroom. Now it's also working perfectly. While I believe that the ground loop was part of my problem, I believe multi-path interference was also part of my problem. The problem is that the house wiring was picking up some of the signal from the transmitter and re-radiating it into the receiver along with that directly from the transmitter and out of phase with it, canceling some of the signal out. This phase difference changes as the transmitter is moved around in the room. The system would work perfectly from the other end of my house because the wiring in my bedroom was not picking up and re-radiating the interfering signal. The solution was this: I lined the plastic electrical box in the bedroom with aluminum foil to simulate the metal electrical box that was shorting out the interference in the living room box. The system is well designed, but it transmits a complex signal at a high data rate which makes it sensitive to things like multi-path interference. The older remote light controls, while also operating at 433 MHz, transmitted at a much lower data rate, making it much more forgiving of interference. The self contained units that plug into the wall probably deal with this in the PC board layout. CONCLUSION: Cut off one of the neutral wires and if the electrical box is not metal, line it with aluminum foil.

The product worked really well. Great solution.

Device works perfectly as described. If you understand the wiring scheme of a switch then hooking this up shouldn't be an issue. This can easily be wired into existing electrical system, and is a good size to fit into your average standard switch box, assuming it doesn't have a bunch of passthrough splices or separate feeds insixe of it. I personally used this in my RV to let me control the overhead lights at will, as A) the only switch is in an annoying location, and B) my lights and thus the switch are 24vdc so as to run off battery backup. I used this device to energize a wafer relay I also installed with the N/O set run in parallel with my rocker switch. Works like a champ. The only thing I'd suggest one keeps in mind is that having your typical light circuit run via a device that uses batteries, especilly non-standards, introduces a potential for issues. For example, in my case due to how I wanted it wired, if the lights were on and the batteries died in the repote, the lights could not be turned off with the physical rocker switch as they are in parallel. Naturally, tripping the circuit breaker would reset the relay back to off and allow the rocker to then work as normal, but that's not something a layperson who doesn't spend their days thinking about electrical circuitry would know about / consider. This device is just an example of something where you could install it 100% up correctly and yet potentially create issues -- or, rather, nuanced operation in things that are otherwise typically completely idiot-proof. So be clear -- this thing is absolutely amazing and totally ideal for cheap, easy circuit control. I'm definitely gonna get a few more for some other projects I have. I just personally would be quite warry about trying to install them for others, professionally or otherwise. Late night calls about how you did shoddy electrical work because their lights won't turn onn/off are to be avoided. Speaking from experience, the fact that it's actuallh a dead battery or lost remote rather than your work isn't much solace at the point you've already woken up from a dead sleep to answer your phone!

I love being able to turn my chandelier on and off since there is no wall switch. Only problem with it is that it flickers for a few minutes then steadies out. Not sure why it does that?? Had a professional put in in. Will only let me post 1video, so I posted steady one.

Works perfect got a new light fixture and never noticed the old one was remote only no wall switch this worked perfect it was small and fit under the base so it’s hidden. AAA PERFECT

When my house was built, a stub for the future pool light was supposed to be included. Of course they forgot that detail somehow. The pool light switch is on an outside wall about 50' from the patio door in a wet location. This device allows me to turn the pool light off and on from inside the house. I have no idea how long it might last, but it works very well for now. I know electrical work well enough to install light fixtures, outlets, ceiling fans, and switches, and this was a breeze to install. To use this switch, your box must have both hot and neutral wires. Many light switch boxes have only the hot wire, so make sure yours is compatible before purchase.

Great product. Used it to be able to turn the 2 overhead lights off while the sink light stays on that are all on the same switch.

Works well. Pretty fun to control the light in bed. The component to connect with the light and power is small, and it's easy to install in the original box.

I had tired others brands that didn't work (among other things the remotes had no batteries or information that you would need to purchase one or even what type). I wanted to have two remotes (we have two cars) to be able to turn on a yard light at night. Trying to back the car up in the yard when it's dark has been a problem. There are no street lights near our home. The Dewenwils unit I bought not only works but I have found that it works at a much longer range than advertised. (I've added a couple of photos to show how I installed the control unit on a wall plate. This is just the way I did it and not in any way intended to be a recommendation from either myself or the Dewenwils company.) The unit comes with one remote and the company doesn't offer the remotes separately. I ended up purchasing a second unit to get the second remote. An added expanse but the original price is reasonable and now I have a spare control if the original one ever fails. It's so nice to find a product that works the way it's supposed to. I could wish the company would offer offer the remote (key fob) separately. I found their replies to my e-mail questions via their contact site to be very prompt and helpful. A good company to deal with all around. There is more to the story! I did order another type of device from this same series (a plug-in remote control). That remote worked with both the new unit and the original but when I cancelled the original remote to make this new remote work the original stopped working. So, in my mind it appears that the different types of units (wall plug, for example) have dedicated remotes that will work only for each type of product. I finally acquired as second unit like the original and what do you know now both remotes will turn the light on and off just like I wanted in the first place. Dewenwils has my overall best rating! A great company to work with.

I installed this to my bathroom vent fan. The fan was on all the time according to the city building code requirements. I understand the intention is good so that the we don’t have excess moisture build up in the unit, but the fan humming noise at night is causing me hard to sleep. So I installed it to the fan and now I was able to turn it off at night, turn it on in the morning.

Bought this more than a year ago, works great!

I like it

I was very pleased with the size. I could be tucked in the canopy of the fixture and hidden completely. Easy to hook up and only took a few minutes. Works perfectly.
