I have two ISY-994i PRO units. I migrated the z-wave devices that would not function on a ISY-994i Pro unit with firmware version 5.1.0 to my second ISY-994i Pro unit running version 5.0.15A. The migrated z-wave devices now seem to be functioning.
I have one exception. I received a new z-wave ZooZ outdoor motion sensor, ZSE29 version 2.0, which does function from either of the firmware versions mentioned above but I can not set any z-wave configuration parameters.
