I don’t have that device but I would expect it to pick up the stock Zigbee Motion Detector as that has the device fingerprint in it. It doesn’t run locally because other devices supported in the DTH don’t report ‘inactive’ and the timer it uses for those wasn’t handled locally in the hub way back when. Whether that situation has changed and it could now be made local, I wouldn’t know.
Do you really need to delete the device, or do you just assume you have to? It is unusual not to be able to simply pair again.
