Replace button?

[JDRoberts]

There’s a replace button on a zigbee device in the SmartThings mobile app? Can you show us a screenshot? Normally that’s only for Z wave devices.

Replace Device doesn't work

No, the replace utility is specific to Z wave devices and will not work with zigbee. This is because of the difference in how the two protocols assign device IDs. With Z wave, it is the controller that tells the device what its device ID will be at the time that the device joins the network. This is why it is possible to reuse an old device ID for a new device. With zigbee, each device has a permanent ID which it tells to the hub at the time that it joins the network. So you can’t have a new device take on the identity of an old one, it just doesn’t work that way in zigbee.
