Review on RF Remote Control Switch EMylo Smart Wireless Relay AC 110-240V 2000W 1 Channel Momentary 433MHz Module With 2 Transmitters by Johnny Moger

Installed this on a garage door opener that is 20+ years old and remotes can no longer be bought. Since the opener works great still I figured I would give this a shot. Result is amazing and my remotes have longer range than most other openers, 100+ feet with remote inside my vehicle not pointing at the garage. Remotes are very tiny, smaller than any keyfob remote for a car. If you ask the seller they will send you a link to buy more remotes. Does not come with power supply but I have them laying around my house, 9v 2.5amp worked just fine. Just make sure you know the amperage limit for power supply is 10 amps. I'd say security for this wireless system is pretty good considering just about no garage door opener works with 433mhz. I even tried a 433mhz remote I had for a gate opener on it and the device wouldn't learn it due to a different learning code on the remote so I'd say don't worry about it not being secure enough!
