Let me please add my vote "yes". Either a way to manually enter the App key# and a UID #, or include a 8.5x11 paper copy of the QR in the box.
The camera on my inexpensive (ie, cheap) android tablets I use for my home automation, have a problem focusing on something that small and close-to-the-lens. It is meant to focus on a human head a few feet away, and doesn't handle close ups of something that is smaller than a postage stamp (can't focus). Yes, I use these cheap tablets because it isn't all that big of a loss if one gets dropped or sat upon.
BTW, I have this problem with my GE Connect devices, because they register basically the same way (the app taking a pic of the bar code on the unit).
