I just got three of these new Zooz ZEN77 700 series dimmers. I cannot get them to finish pairing. They get stuck on initializing and therefore will not discover it's capabilities and install a driver.
I have tried to include them with different authentications.
I have even disconnected all my other zwave devices.
After Pairing my ZEN71, I also had issues. I had to uncheck "Security 2 Class 1 - Authenticated" and manually set the Type and Device Name to "ZooZ Central Scene Switch to get it to work. Try it and let me know.
