I experienced a strange behavior this morning. My Dashboard showed a new device needing configuration. It turns out SmartThings thinks that I have added a new Centralite switch to my hub. I did not, and I only have one such switch, which is also still showing up on the device page. That one has been added months ago.
The device has a Device Network ID, different from the real switch, but no ZigBee ID.
Has anyone else seen new devices appear out of the blue?
