I have the August Door Lock and based on what I have been able to find out it cannot and will not pair with the touch screen. Only works with the App. Kind of a bummer that Comcast is pushing us toward these devices but don't fully support them. The Kwickset lock is identified as being supported will pair with the touchscreen.
Comcast indicated in a news update that there may be updates that will correct this but I am not holding my breath.
