Hi Gaurav,
Firstly – do be careful with these switches. They create a permanent connection from your network to a Chinese IP address. You need to isolate the network – if hackers crack Lanbon then they have a direct connection into your network.
If Lanbon go bankrupt or stop supporting these switches, you may not be able to control them.
I suggest asking Lanbon for the API details. If they won’t provide them, you can try decompiling the APK and see if that helps.
Best of luck.
