Yes, you can use a boolean input and it provides an On/Off slider (at least in iOS it does; I imagine it does similar in the Android / Windows Phone apps)
This would actually be a great feature within the iOS and Android app itself (or at a minimum in the IDE). I would love the ability to enable/disable apps or devices temporarily for troubleshooting or other reasons.
Thanks @JDRoberts. I tracked it down and we’ll get it corrected (no copyright violation or anything, just an apparent old test docs location that never got cleaned up)
