Smart RF Relay Switch eMylo Wireless Remote Control Switch DC 12V RF Receiver 433Mhz Relay Module Home Automation with Two Transmitters One 1-Channel 1Pack

The only ceiling light for the bed of my trailer was over the bed and it required getting on the bed to turn the light switch. I installed this into the hole of where the wires come down for the light and with the two remotes it is now so convenient. This is the 1 channel with 2 remotes. I liked that it came with the wires and clamp on connectors, and that it has a wider range of input DC voltage. The current draw on standby mode with the light off is 82ma. So it is not that much of a drain on the battery. The A button is for on, and the B button is for off. Works great. Would buy again.

I was initially a little confused how to wire these up, but that was entirely me making things harder than they needed to be. Currently I am using two of them,. One to power up my backup cam camera/server for wireless backup camera - which works wonderfully and keeps me from having the cam running 24/7 draining the battery and/or having to wire the cam to the backup lights.Second relay I have doing the duty of energizing two other 40amp relays for LED fog lights. This too works awesome, and made it so I didnt have to butcher the stock harness in my BMW. All in all, a great product.

The range of the wireless remote was only about 5 feet therefore it is useless. it was advertised to have a range of about 20 meters is I recall correctly.it is a piece of junk, do not buy.Why does Amazon sell such junk ? They must not test the products they sell, just take the word of the seller.

Worked perfectly for my intended application. Easy to install with simple instructions. Would buy again.

Unit performed as advertised concerning ease of installation and operation. I was disappointed in the very short range of the remote. Claim was 20-50m. HA HA Best so far is 30' in direct line of sight. Excellent connectors

Yasorn (the seller), has a variety of these relay switches. Some are wireless rf & some are "Smart" switches that connect via WIFI to Alexa & other smart home universes. Yasorn calls their wireless switches with remotes "Smart", which led me to order the wrong one. I can't return it.They also have 12v & 110v versions. In haste, I chose 110v when I needed 12v. So I have 2 I don't need. The one I need--12v Smart (Alexa capable)--has a delivery date well into December. So I'm 0 for 2 and trying a different brand. As far as I know, they work fine. They're the best looking of the lot & include the new-style connector for free. A nice touch. But if you order wrong as I did, it's an expensive way to get 2 connectors.

Good product but first one did not work after second day. Returned, contacted customer service and they sent a new one at no cost. Second one worked well.

Works great the little clips on the ends did not work very well but overall this product works super great and once I disassembled it was much smaller and easier to install it in my helmet 100% recommend if you’re doing small or large projects or whatever you want I really don’t care just came on here to say that it works great😂
