eMyloRemote Control Switch DC 12V Wireless Momentary Switch 1 Channel Wireless Relay Transmitter with Receiver for Home Use

I used this to set up a wireless trapper station for a shotgun range I work with. I can set up six wireless clay traps, all to be operated by one trapper. It sure beats having to string out all the cords for the manual releases we were using.

I haven't used these extensively, or heavily, but it does what it's supposed to do quite well, especially for the money. The lack of decent documentation is the only real shortfall here, not only the manual, which is *barely* more than the listing info here itself, but that is also limited and somewhat misleading as the "Questions" section here appears to have 5 years or so of inquiry and response that may or may not be limited to this particular device. Lot of the responses indicate that this unit can only be used on all channels with one mode (latched, jog, toggle) exclusively, however that is *not* the case, and the 8 channel latched + 8 channel jog mode (there is also a 1 chan latched + 15 chan jog mode) is one of the nicest features of this unit to me. TLDR, you can program this easily so that half the channels are latching (aka one press on, turns on and keeps that circuit on, until you press again and it turns off), and the other are "jog" (aka press and hold keeps the circuit open, release the button and it's closed (off)).It's also not made clear that each relay is independent, and the included "wiring diagram" if you can even call it that, makes it less clear. Nothing really highlights the fact that these relays can control either AC or DC circuits separately either, although a glance at the relays and a bit of electronics knowledge should make this obvious, though that further exacerbates the aforementioned wiring diagram, as you *definitely* do not want to mix devices and daisy chain relays the way that diagram shows. The *good* news is you can wire each one separately and independently, which is necessary for any scenario that expects to utilize any amount of the relays near their current capabilities.The board itself does require a 12-24VDC power source for it's operation which is (or can be) independent of the circuits or source for the devices being switched, and idle power draw appears to be low enough as to not register outside of the margin of error for my DC clamp meter (sorry haven't hooked it up directly to test, but I would guess under 200mA at ~12vdc). I'm using it directly connected to 12V nominal lithium storage and haven't seen any hiccups before BMS's kick in. 35V caps on the board make me think the input range can actually handle fully charged 24V nominal LA or Lifepo4 battery packs i.e. ~28.8V but don't take my word for it. I would love to see a 48V nominal input version but that's a minor convenience only, as any $4 buck module should be more than capable of powering this device from a higher voltage source.Anyway, great little module, the extra controller is a nice item to have, though the old-school telescoping metal antennas make the whole thing seem dated AF and I personally will reserve their use for times when I'm lighting a stick of dynamite with a cigar in my robe outside of a burning industrial complex, as I'm pretty sure I'll break it immediately otherwise. For my use inside a relatively small space I haven't needed it. *shrug* A more modern and aesthetically pleasing controller/remote would be nice if they refresh the product but only if they can leave the rest of it alone, since I know I'll be needing more of these units!

Very easy installation. Before installing, you have to test first. Signal is very strong so it works more than 10 meter distance. Excellent product.

I purchased this UNIT to use in the MOMENTARY mode (to energize the relay only while the remote button is held down--similar to momentarily pushing a button) and it was a little tricky (took me about 4 times) reading the instructions to be able to reprogram it. It comes shipped in the mode that most people would probably want (to toggle a light or appliance ON and then to push the button again to turn the light or appliance OFF.Since my garage door opener receiver board went bad, I just needed something to electrically push the wired garage door button on the wall for me. This little unit (once reprogrammed) works fantastic!What I liked:- The receiver did exactly what I wanted it to do (momentarily close the contacts on the garage door pushbutton switch on the wall).-The unit even worked great with a 9V battery (used that to make sure I knew how to program it) but I then connected an inexpensive 120VAC to 12VDC adapter I got from Amazon for $4 to power the unit- I was going to uncoil the antenna wire inside the receiver (for a greater distance) but before doing that, I walked 120+ feet away from the garage door and pushed the button and it worked great!What could have been a little better:- The instructions are somewhat unclear when you are reprogramming the unit for MOMENTARY mode, but after I read it numerous times and memorized what I had to do, since you only have a short time to continue programming, everything worked OK. The trick was holding the button on the transmitter down (on the last step) UNTIL you hear the relay click.OVERALL: I like the unit and it saved me from buying a door opener receiver circuit card ($100) or a new garage door opener ($150+). If your garage door opener works by pushing the wired button on the wall, but doesn't work remotely due to a bad internal circuit card, this is a great inexpensive fix.

Tried to wire 2 12V LED flood lights on it and was having difficulties. Then followed wiring instructions Howard Gray posted in his review. Both my 12V 50W LED spot lights are now individually controllable from inside my house.The housing for the board doesn't really have enough space to run all the wires, but for $15 for a 2 channel remote, I've got not complaints.
