Do you want a "wand" type of user interface? If so, should this wand be a simple "black remote" or have a graphics display with the option of customized text (not touch sensitive). Next in line is a wand type with a small touch screen. Finally, there is the pad/phone App with a full GUI.

Most of the GUI units are programmed through a web portal. Some offer rudimentary visual layout control, but are quick and easy to master. Others offer extensive customizations, but along with this comes a learning curve.

Are you comfortable with computer programming languages?
