Hi everyone,
I installed armored roll-up railings that can be controlled with a fixed code RF e.go P 433.82 MHz remote control. Since these are security railings, unfortunately only now have I begun to doubt whether these remote controls can be easily cloned, even more so because they have a fixed code.
I wanted to ask you:
Is it possible to clone them only with another device to pair by placing it near the current remote control?
Are there other ways of cloning?
Is it easy to unlock the control unit remotely without cloning the remote control?
4)Are rolling code remote controls much safer?
If someone had enough time and skill, yes it would be possible.
However most RF gates etc have their own "key" set in the software, the likelihood of someone opening your gate is very small, most would look for another entry.
Please provide a link to the product.Where you bought it or a datasheet or whatever, or explain what it is you doing if hand made.
But google finds someone very busily presenting this problem to fora all over the place, woukd that be you?
It would be polite to say everywhere you post this inquiry that you are doing a wide distribution, involving dozens of unwitting helpers who are at a disadvantage and will no doubt be repeating advices given elsewhere.
If that is you, you are being rude. If it is just some coincidence, that is just some coincidence.
Italian, r/arduion, stack exchange, where else?
Don't worry about me, I got nothing on this. Just curious and bemused.
So you bought receiver unit and remote control for fixed code?
It's not very safe. With inexpensive hardware I can clone it 100 meters from your house.
Could you tell me what hardware could add remote control from 100 meters so I can buy and test it and send that proof to the company who sold me prodcuts
Good quality RTL-SDR with good antenna would be my first choice.
Flipper Zero with external CC1101 module could be an option.
Even just CC1101 module with esp32.
It depends a lot how much 433 traffic there is around, If you live in place saturated by 433 signals, it's going to be more difficult to catch and identify the "right one". Directional antenna might help.
There is no defect with your "product". There is no protection to be cloned in common fixed code rx/tx. Rolling code makes simple cloning impossible, because every signal is valid only once. If you send it and your receiver receives it, it's not valid anymore even if I cloned it.
