I’m setting up a new ADT/SmartThings hub with various sensors. After the initial installation, the hub would periodically lose supervision of Sensor 2, and cause an error preventing the system from arming. The problem is, all of my sensors were accounted for–there was no Sensor 2. It is a ghost (phantom) sensor.
I then tried a factory reset of the hub. After setup I connected no sensors. Despite connecting zero sensors, the hub still shows the ghost Sensor 2, and it throws and error when it loses supervision of this ghost sensor.
I called SmartThings support, and I was told they are aware of the issue. They said “there is a fix, but there’s not a fix”. The guy couldn’t/wouldn’t elaborate. He said someone would call me back within a few days, but I’ve heard nothing, and I’ve been unable to get support on the phone since (wait times over one hour).
I welcome any input anyone can offer. I really would like to get this functioning correctly. Any ideas?
