DieseRC 433Mhz Universal Wireless Remote Control Switch DC 12V 1CH RF Relay Receiver Module with 2 Transmitters, EV1527 Learning Code Remote Switch

How do you salvage a very old garage door opener that is still mechanically sound but the remote(s) are failing and no longer made? You get one of these remote control switches and you have a more modern solution at a minimal price!The good:Extremely easy to install.Works well.Can be configured to operate in multiple ways: momentary switch, toggle or latched. To work withe the garage door opener, momentary contact is the applicable mode.As ca be seen in the pictures, the receiver is extremely small. This facilitates its installation (anywhwre) but also requires careful handling when attaching the wires.Installation tips:You need an external 12 VDC power source. I used a discarded wall charger that I had from an unrelated product.My unit came pre-configured in latching mode, so I had to configure it to momentary contact operation. Just follow the instructions for configuring the modes in the attached booklet, don't try to reset or pair anything. Two clicks and you're done.I found that each remote had to be configured to operate in momentary mode separately, i.e. I first thought that a single mode configuration would have been sufficent; not so, I had to repeat it for the second remote.For some applications, the above may be a useful feature, as you can make the receiver operate differently depending on which remote one uses. Not my case as a garge door opener.The remotes feel well made and I ordered visor clips to put them in the cars.In summary, I am very pleased with the product. It solved my needs and added life to my ancient garge door opener!

Easy to use and always works. Have used on several special effects at my theater.

Just what I needed to control my Central Vacuum wirelessly. The remotes were all pre-programmed for On-Off control so no reprogramming was required. Used a 12VDC power supply from an old router to power it.

Works well and the price is right. Instructions are... adequate... at least for a hobbyist... But I wouldn't describe the item as plug and play.

This was a perfect, low cost solution to replace the receiver on my garage door opener. It was a very easy install. The signal works from several houses away.

The remote transmitter will activate ("ON") the NO just fine at 50 yards. BUT, the "OFF" button won't work >3 yards. Both remotes that shipped with the controller suffer this syndrome. I don't get it, I just don't get it... it's just digital bits in RF land, same power, same distance, different 1s and 0s. Unusable.

This device works well as a remote momentary switch for a hot water pump attached to a whole house tankless water heater. It goes through four walls to the control unit about 30 feet away. It may go further but I did not test it. The remote looks and feels high quality. It lights up a red LED when the ON button is pressed.The black plastic box holding the unit might crack and become brittle in the future but it won’t be a problem if you never move it or touch it. It looks cheap but it’s small enough to easily hide.I have not had to restart it after a few weeks of usage. In my use case, it is an easy install as you only need to screw in two screws for the 12v power supply and two wires for the pump.

Exactly what I needed. Essentially an RF controlled relay. Can be wired NO or NC, and came with the remotes already "learned" by the receiver.
