Hello @pakyeechan

This is my opinion about your application

Pros:

With 7 recommendations provided by Wink Hub it shows that all smart applications you can control in one container that will make our lives more effective and efficient. Is not this an amazing thing.

Cons:

As you said earlier, the source of energy coming from the battery is pretty much a drawback.

Lastly
This is the value I give to your product
