Review on 🔌 Wireless RF Relay Remote Control Switch, QIACHIP 12V 1CH 433Mhz Momentary Light Transmitter with Receiver (1 Relay) by Jason Khadka

I've used wireless switches before. I required a two switches for two 12vdc vent fans in my RV. My challenge was finding one where the remotes were addressable so each remote would operate their respective relay. This one fit y application perfectly and then some. The remote has an A and B button. I have it programmed/addressed so A operates one fan and B operates the other. I would have rated 5 stars if the relay had come with some instructions. You have to use the instruction provided here in the images of the product. They offer two wiring diagrams but fail to mention which one you should use for your application. I chose the easy diagram (one I've used before) which didn't work. I had to use the top diagram (in provided image here on Revain) which too some mental gymnastics to figure out but it worked. Besides that, I'm very happy with the final product.
