Unable to connect to switch

Hi, I am currently to to implement this with php instead but I have been unable to do it. I have a feeling the encrypted message sent is wrong. Below is my encryption method.

function encrypt($msg){ define('AES_128_CBC', 'aes-128-cbc'); $encryption_key = "9521314528002574"; $iv = "4528453102574529"; $encrypted = openssl_encrypt($msg, AES_128_CBC, $encryption_key, 0, $iv); //$encrypted = $encrypted . ':' . base64_encode($iv); return $encrypted; }

I have also tried sniffing the TCP packets from my router however I am unable to get any packets sent during the "on/off" function of the switch when using the mobile application. I am only able to capture periodic packets send, probably the packets that are sent to the server which you mentioned.

Any help would be appreciated.
Thanks.

After troubleshooting abit more, I managed to get everything working correctly, both tcpdump and the script for the switch. Thanks!

Based on your reply on the previous issues, I am guessing, after sniffing the packets, you decompiled the "HF smart home" apk and got the encryption key and IV from there?
