Last year about this time there was some whispers of a bluetooth or wifi contol unit that would interface with the EZ command controller and allow you to use it with the EZ App. Did that unit ever come out, or was it scrapped?
ADDED: It's called the smart interface and was suppose to be out spring of 2016.

We're sorry, but we are unable to offer the E-Z Command Smart Interface.
