Word of warning, be cautious with that. It requires internet access to be ON, as well, the phone app will use things on your phone.
I thought of using the Samsung Smartplug which is very similar to this, because of the phone access, monitoring & control. But to install the app, you have to give it permission to everything on the phone, browse, photos, address book, gps… pretty much everything. I'd call that a Red Flag. In my case without data on my phone the app failed during the initial install and was told by Samsung that it had to be on, which was the eye opener, that's also when I found out you had to give access o everything on the phone. WTH for ? wifi to device, info to & fro from device, why web, why all access, why, why why ??? no good reason I can think of, should be optional and selectable if anything.
Different products do & want different things but just be cautious with these things, you could end up with more than you bargained for.
