--------------------
On the A+, tap "Add Sensor" (Screen 1, lower left) and tap "Add"
On the Scalage BE469NX:
1) Extend the deadbolt
2) Press the Schlage button, keys will light up
3) Enter your 6 digit programming code (see your Schlage manual), orange light will light up and be steady.
4) Press "0" and the orange light will start blinking. If your A+ is still in Add sensor mode, the two devices will start communicating to pair.
5) The Schlage will beep and show the green checkmark if successful.
At this point, the A+ will say adding sensor, then getting sensor info, then it will prompt for a name and location.
