Continuing the discussion from Leviton Visia RF + compatibility & differences:
Can the z-wave utility, Join/Leave another network, be used to join the ST hub to an existing Leviton Visia RF + network?
The short answer is no. Leviton uses the word “join” in a special way. See the other topic.http://community.smartthings.com/t/can-i-join-a-vizia-rf-network-with-z-wave-utilities-join-leave-another-network
