I installed the app, paired it to my iPhone 6S+ according to the instructions, and the first time I opened up the app, everything worked FLAWLESSLY!
The problem is, when you exit the app and re-open it, it asks you to set up the device each and every single time. I looked in SETTINGS and checked my Bluetooth connections. There are two for this device: one is for the iHome iZB10 App, which it is always connected to, and the other is the iHome iZB10 Device itself which it connects to ONLY after you open the app, and set it up to be recognized yet again.
In short, THE APP
DOES NOT RECOGNIZE THE PHONE UNLESS YOU SET IT UP EACH AND EVERY TIME YOU OPEN THE APP.
This is incredibly inconvenient, and the developers need to work on this flaw. Outside of that, once connected, the app works EXCELLENT!
