ghost device showing up in HomeBridge
this is a weird error, and totally understandable if it's too much of an edge case to fix.

I have a Aeon Labs z-wave plug-in outlet that quit working reliably, so I unplugged it for a couple of days. Prior to that, it was selected in the JSON Complete app and usable through Homebridge. While it was unplugged, it disappeared from SmartThings, and it didn't come back when I plugged it back in. I mainly use it on a schedule, which SmartThings can't handle right now, so I just excluded it using my other system (openHAB with a Z-stick) and re-included it there, where it's working fine. 

The problem is, the homebridge-smartthings plugin is still exporting it to HomeKit, where it is reporting its last known status and appears to be accepting on/off commands. I can't delete it from iDevices app, and it no longer appears in the list of devices under the JSON app to unselect it. 

Short of wiping out my JSON app and re-installing it, is there anyway to remove this ghost device?
