I had one very useful scenario for this app. I wanted to use an automatic routine which would turn the Sabbath Mode on my Samsung refrigerator on at the beginning of every Saturday, and off at the end of Saturday. The custom routine has all the functionality to do this, the only problem is that Sabbath Mode has been set to be a Refrigerator Option, and Device Options cannot be controlled though a Routine. If this were possible I would give it 5 stars.
