What does Z-Wave Replace do in the SmartThings Classic app?

"Z-Wave Replace" is a special feature of the Z-Wave protocol that allows you to replace an unresponsive device with a new one of the same type. This gives the new device the network ID of the failed one, so it works as a drop-in replacement with minimal reconfiguration.

To remove and replace a Z-Wave device using the SmartThings Classic app:

  1. Tap My Home
  2. Tap Things
  3. Tap the failed Z-Wave device
  4. Tap the gear icon
  5. Tap the red Replace button
    1. The Z-Wave protocol will first attempt to communicate with the failed device to confirm unresponsiveness. This process can take several seconds
    2. Once the device is determined to be unresponsive, the Hub will search for the replacement device
  6. When the Hub is searching and indicates the device is ready to be replaced, perform the replacement device's connection (or "inclusion") process. This process is specific to the device. If your device is compatible with SmartThings, search our support center for connection instructions, or consult the device's manual
