Connecting ADT devices with code-based pairing

ADT devices require a two-factor authentication to connect. First, both the ADT device and ADT Security Hub must be in pairing mode; and second, the QR code that came with the ADT device must be scanned in the SmartThings Classic app.

Other kinds of smart devices (e.g., ZigBee or Z-Wave) that work with SmartThings do not require code-based pairing. You can find steps to connect your other devices here.

The following ADT devices use code-based pairing:

  • ADT Motion Detector
  • ADT Door and Window Detector
  • ADT Smoke Alarm
  • ADT Carbon Monoxide Alarm
  • ADT Keychain Remote

  7. Remove the battery tab from the ADT device
