Review on 🔌 Solidremote Wireless Relay Switch Kit-1: 2-Channel 433MHz Receiver with 2 FCC ID Transmitters for Garage Door Openers, Cars, LED Lights & More - 12V-24V Universal Solution by Brent Gurney

Worked great. I'm wondering if there's a way to make sure this is actually rolling code as I don't know how I would say if it was fixed code, but hopefully the statements in the description are correct. Current draw is very flexible so finding the right wall wart in my discarded box of electronics wall warts was easy. These are bare bones and I used a few parts I had on hand such as an RJ11 jack and a 2.1mm power jack, but it would work just as well if I just screwed the bare wires into the screw terminals would. I connected this parallel to the wall switch on the garage door opener and can use both remote controls in addition to the existing wall switch
