After creating an account, you may encounter what appears to be an empty Insteon+ app. If Insteon+ shows only a blank display and a blue gear in the upper left corner, you need to create a home.
Create a Home
Open settings by tapping the gear in the upper left corner.
Tap Add a Home
Give your home a name and pick an icon. When you're ready, tap Done.
After you dismiss settings, you should see your new home ready for use.
