LW-12 WIFI Wireless Controller

have just want to take the controller into operation. Have the first controller connected to a 12V / 3A power adapter to test the same time whether the supply is functioning. Have the app downloaded and installed. But unfortunately I can not find the controller via the app.
Have the controller, as described, the reset button more than 20 sec. Down. The green Controll LED lights, but the app does not find the controller. The appears to be broken?
Therefore I can not say much about the product and forgive first and only one point. Before I send the back, perhaps one give me a hint?

Many thanks.

Update:
Hardly one goes ran again with logic to the thing one finds immediately the problem yourself: D
You have to connect the controller via WiFi Android first, then it works!
The controller gets instant 5 points because it works exactly as I had imagined. The app is simple and clear. A tribute to the manufacturer, the board looks clean and the components were clean and stocked soldered. I'm really surprised. Good quality for little money!

Update:
I wanted to order the same article again and got the wrong controller. It is not the right board it. Have to go back again and sent it ordered. AND AGAIN THE SAME! It is not the right board in the housing !!!!!!!!!!!!!!!!
The wrong controller has a security key and is also incompatible with the app from the AppStore!
I also had to realize that the two controllers were ever unpacked. The first real controller was packed clean, the other two were ever opened. Now I feel pretty ripped off!
I would like the same to I initially ordered and not some cheap knock-offs !!!!!
I'd like to communicate directly with the dealer once, but that's probably not possible ??????
