I migrated from v2 to v3 - the v3 hub is connected via ethernet (could not get successful connectivity using Wifi).
I have reconnected smart apps (Google Home, Alexa and irobot) and many smart plugs. I cannot connect any of the my Z- Wave dimmer switches. I have several brands (GE, Linear, Leviton, etc.). I cannot get ST to recognize them.
I have attempted to exclude and included with no success. ST simply times out searching for the device. The Leviton flashes confirming that it is in pairing mode, but ST will not recognize/pair with it.
Any suggestion you may have is MOST welcome!
