iMILLET WiFi Smart Plug

I have a buddy who has quite a few of these and I was talking to him about the ST hub. I’ve tried to look around and search to see if these can be integrated into the ST hub or not. Can anyone point me in the right direction?

Model: SM-PW702
UL: E489132

Not sure if that UL number will actually mean anything or not.

Anyone? No one? LOL. If someone could point me where to start with device handlers I may borrow one from him and see if I can’t get it running.
