These are probably one of my favorite devices. The only issue is that Smart Things doesn’t register them correctly when pairing. It is an easy fix:
Log into ide.smarthings.com (it should be your normal email and password)
Go to devices
Click on the device
Scroll all the way down to bottom and click “edit"
Find the “device type” drop down box
Scroll to and select 'Schlage Contact Sensor"
Scroll to the bottom and click 'Update”
Repeat for the other sensors and you should be good to go.
