I should preface this post by saying that I only have a little programming knowledge, but have been trying to figure out how to control these plugs for a while now.
My goal is to integrate these with other smart home platforms, such as Home Assistant. This would allow me to bypass the suboptimal CNCT-Alexa and CNCT-Google integration and control your plugs directly.
I’ve been doing a fair bit of research into these plugs. As others have figured out, this is likely a "Chinese company going into business with a US front company"
However, looking online, there are a lot of plugs that look very similar to these intelliPLUGs. When connecting to the plug for the first time, the wifi name is 0K_SP3. In fact, this is the same name used by KanKun Wifi plugs. The older KanKun Wifi plugs had an open port for SSH and people found out the password for it and were able to load their own code onto them. Unfortunately, these intelliPLUGS do not have any open ports (as far as I can tell).
Reading further, I found a group that was actually able to control the KanKun Wifi plug by determining the encryption code it uses to send UDP commands to control its on and off state. From this encryption code they were able to reverse engineer the method to control the plug and could send their own on and off commands to the plug over UDP.
I decided to test this code to see if it would work with the intelliPLUGS. I am able to run it and successfully send a receive a heartbeat - this leads me to believe that the intelliPLUGS use the same UDP process, with the same port, and same encryption code as the KanKun plugs. However, when sending the on and off (open and close) commands to the intelliPLUGs, they do not switch. I’ve been looking through the CNCT app .apk to see if I can figure out if they use a different on and off command than the KanKun plugs, but I haven’t been able to find anything. Hopefully someone here who knows more about programming and could help me out as I think this (hopefully) is a good start and could be easily fixed/implemented.
