I purchased this in an effort to have Alexa be able to control my living room lights. I have just spent an hour trying to set the app and this system up. I noted with chagrin that the required "EFamily" app has a 1 1/2 star rating in the Apple Store.
The instructions are not clear (in an English is a second language or a computer translated them kind of way). It seems like the English isn't very strong on some of all the five star Amazon reviews that induced me to purchase this too, which is now making me a bit suspicious . . . The confirmation code to set up the app was in what appeared to be Chinese characters. I am feeling very uncomfortable at this point in having my WiFi system associated with this. The plugs are going back and the app is getting deleted.
Next time I am going to check the rating on the app before I buy hardware.
