Why My RF Device Can't be Controlled?
The incompatibility with your RF device is likely due to its use of rolling code.
Rolling codes (also called hopping codes) are commonly used in radio frequency (RF) control systems, especially those requiring strict access control or enhanced privacy.
How it works:
Your remote sends a digital message to the receiver.
If the receiver finds the code in the message acceptable, it triggers an action (e.g., actuates a relay, unlocks a door).
Simple remotes use fixed codes that remain unchanged, meaning the same code that opens your gate today will work tomorrow. This makes them vulnerable to attackers who could intercept and use the code later.
More secure systems employ rolling codes that change with every use. While an attacker might capture the current code, it won't work for future attempts.
Rolling codes employ encryption methods allowing the remote and receiver to share codes while making it difficult for someone to crack the encryption. This technology is also used in some curtain/blind/shade motors for increased privacy.
Therefore, even if the eRemote successfully learns the RF code, it cannot control your device. This is not a flaw in LinknLink technology, but rather the intended functionality of rolling codes, designed to prioritize security and privacy.
