Thanks everyone,
I am using mike's driver from above. That talks to an alarm system bridge (originally developed for smart things) that communicates to a Networx NX-V2 panel via an NX-584e automation module. The bridge is communicating with the panel, and I am able to connect the bridge to Hubitat with the driver. Hubitat is able to see the state of the alarm (armed/disarmed) and to arm it. It is able to read the device names from the panel and generate child devices. The child devices are all automatically assigned the type virtual motion sensor.
The problem is that the virtual motion sensors that it creates don't work. I checked the logs, and I get this when I activate one of the physical motion sensors.
