12V Relay Remote Switch Wireless RF Remote Control Switch 4 Channel Relay Module 433Mhz Transmitter Receiver Kit Universal Remote Controller for Lights Ceiling Fan Garage Door Opener Gate Car & More

I built a camper in 2019 and have been upgrading it. I wanted to add more light so added 8 more puck lights in the process of installing a cedar ceiling. They are on an overall remote control linked in with 6 lights in the kitchen area. That gives me overall control over the on/off and dimmer function. I wanted to be able to control the on/off function of the 8 new lights individually in zones of 2 lights. The little remote circuit allowed me to do that. Each 2 light string was connected in series into a central distribution box. I just broke the positive line to each string and inserted the relay on the new board. That worked giving me on/off control for each leg individually. Worked like a charm. I would buy again in a heartbeat. I especially liked the wire terminals. I was able to crank down on the wires quite hard. Nothing stripped. I know those wires are not coming out any time soon. All soldering seemed quite good and programming was very easy. This was a great buy. I wish I could say the same for many other electronic circuits I have bought.

I bought two of these about two months ago. One was installed in my buddy's barbershop as a temporary solution to switch a shopvac while his central vacuum unit for six barber chairs is being repaired. It has been used six days a week since installed and switched on and off several times per day with no issues. The remote works good as well. The receiver and shopvac are in an adjacent room and the signal has no trouble going through the wall to the other room. I used the second switch on my garage shop vac that I use for several wood working tools. It works great. I only have two negative comments. The first is they are a sort of a pain to pair the remote. Each switch took a couple tries to get them in the mode I wanted. Not that big of a deal, because you don't have to do it again unless you want to change modes. They hold the setting even if the power goes out, which leads me to my second negative... The power has gone out a couple times and the switches turn on by themselves when power is restored. I had a shopvac run for several hours in my garage one day while I was at work. Turn it off with the remote when this happens and you are back to normal until the next power interruption. I have the remote switch wired ahead of my shopvac, so to keep it from happening again I just turn off the power switch on the shopvac itself when I am done for the day.

Dry relays turn on themselves without button presses. Makes this completely useless.

We use this to open an access control door remotely by "triggering" a handy cap button input. Worked great all summer. Winter came and we started having random door openings towards the end of the work day. Finally figured out that car remote start key fobs were triggering the device. Apparently car remote starts work on the same frequency as this device causing false activations. We moved another relay on the device and it stopped. I'm thinking a re-pairing on the remotes may fix the problem as well, but we have not tried that yet.

Got this working on my hydraulic trailer, but needed more than explained in the directions. I cannot find any reviewers who explain what to do when you need to power a common point on both directions. My hydraulic pump has two electrically-activated valves-one for up, one for down-but I also need power to the solenoid that controls the pump motor, and this power has to be on for either dirextion. One relay from this remote goes to the up valve. One relay goes to the down valve. I could have run a third relay for the pump motor, but would then have to push two buttons to operate the trailer hydraulic. Solution: tee the power from each valve through a diode and then to the pump solenoid. You have to install diodes to keep power from either valve from back-feeding through the solenoid to the other valve. Once that solution was implemented, it works great. Haven't played around with it enough to have a good sense of what distance the fob reliably talks to the relay. May update the review when I next need to run the trailer and have time to experiment.

great product. controlling lights on my boat

I got the unit wired into my outlet and tested it before pushing the outlet back into the box. It worked great starting my dust collectors. I pushed the outlet back into the box and retired for the night. The next morning it appeared not to be working. I emailed the customer service and Aubrey responded very quickly with some suggestions on how to remedy the problem. None of the suggestions worked, however I checked for the connections in the outlet box and found one not connected. How foolish I felt. Making the connection again everything worked great. Every time I emailed I got a response within an hour or two.

The Term Learning Button is only a Remote Pairing button ,,, not relay learning as I expected. Here is my scenario. Button "A" - A Jog button ( momentary) Button "B" - Forward Reverse (Latching) I was under the impression from reading that I could put the jumper in the mode I wanted (Momentary) then press learn then the "A" button .... then change the jumper to Latching ... press the learn button then press "B" and I would have "Independent" functions on those buttons. That is not the case ... the jumper determines the "One" and only function all relays follow. If you need only latching or momentary etc. on "all" the relays then this will work. Mixing functions is not possible. So, because of the use of the term "Learning and Independent" instead of "Paring Button , mode jumper" I will give a rating of 3 .... Nice unit .... easy setup ... misleading terms (language problem ? )
