I have 2 different houses with different camera sets. When I open the app I want to select the home I want and show only the cameras for that home, but I can't figure a way to assign a camera to a home, the options are greyed out. 

Also, is there a way to have more than 32 cameras in my account? I have a big project that will require over 100 cameras but I need to be able to easily switch between them when using the app, I don't want it to be a mess with all cameras listed at the same time on my home screen and I don't want to use multiple phones/accounts just for that.
