Wireless Remote Switch DC 8V/12V/24V/48V/72V/86V 30A Relay RF Remote Control 328ft Long Range for Anti-Theft Alarms Security Systems Roller Lind Door

So simple an effective. Works great though the range may be a bit less than advertised.You get a lot for the money.

Nice little gadget. Have some a-hole neighbors with junk vehicles (noisy mufflers) don't get me wrong... love the sound of high performance. So bought this gadget to hook up a train horn to give a little feedback when they drive buy. Works great love the remote capability so I don't have to be in my truck to operate.

So, the receiver on the logic board of my chamberlain garage door opener went bad. Since the logic board was too expensive and the wired push button still worked, I used the remote controller, together with a relay and a 9 VDC power supply, to fix it. Very simple and elegant solution. Now I use the remote configured as a momentary switch wired in addition to the wired push button (which still worked). Cheap, simple and elegant solution. Additional components you need to get: a relay and a power adaptor. It works! The photo shows the wiring and placing of the remote receiver with the relay hot glued above.

The media could not be loaded. I installed this on my kids power wheels jeep, for when they drive off and aren't paying attention or listening. It was a fairly easy install into a relay and then a pwm. You can hear it turning the relay on and off in my video.It works well for short range, but the advertised distance is quite the exaggeration. I think I got it to work for 20, maybe 30ft. I had to chase after my kid at the park to get close enough to kill it, and that was in a flat open field. I will try running a longer wire to see if it improves the range.I know this is a remote module, but I do wish it had a switch on the unit to toggle it ON manually, bypassing the remote, or at least a memory to turn back to the last state after losing power. Each time the battery is disconnected/reconnected, I have to hit ON on the remote. If I have a situation where I don't want/need to use it (e.g. My kid is riding around the fenced in backyard), I don't want to have to turn it on for them each time, just let it work. If you don't have the remote or the battery in it dies, you are out of luck. Outside of a couple caveats, it functions well and is a decent value.

Added this to a PowerWheels Gator. Now I can kill the vehicle when the kids are gonna run into a tree!

I had a VERY SIMPLE use I needed this for. In order to extend the life of my garage door opener, which lost its own signal board for remotes opening it; I decided to add this to essentially make the indoor button act as an RF opener. It SHOULD have been easy as pie. But this little unit did NOT bring the voltage from 15-16vdc down to zero, as would the button. Instead it only brought it down to about 7 or 8vdc. That is NOT enough to trigger the motor. I tried several configurations and so on. DOES NOT WORK. I read a bit and it's likely because this circuit board for this unit is not properly arranged and/or grounded or shunted with capacitors. I was using it as "momentary" mode. You can HEAR the relay switch inside... it's WAY too short. Like a tiny click. It needs to latch for a moment, not a millisecond. Even with voltmeters running and such, it was obvious the voltage never got shunted down to zero, or even close. So "have fun" with yet another failure product from CHINA. That seems to be all they sell. Only here in the USA, our options are cheap chinese risks, or HIDEOUSLY expensive US options. An equivalent to this was over $200 here. Insane.

I bought this remote control as an alternative to replacing the failed circuit board in my GENIE garage door opener. I used an old wall wart transformer to power it (12v), and the output as a momentary switch to trigger the door open/close. It is great - the range is further than my old garage door opener, the programming was very simple, and the little key fobs look nice. I hope the “jelly” surface buttons don’t melt in the summer heat.

This is easy to install and user-friendly. Great quality
