I have 2 V3 hubs in different locations using two different accounts. Both are on my iPhone using the latest app. Here are the problems:
First hub - Zooz Zen23 switch installed fine. After about two weeks went offline and is now refusing to connect. Manually it still works as an on/off switch but I have tried everything (Z-Wave exclude, etc). I have a First Alert Z-Wave smoke detector which still works on the hub.
Second hub - GE Outdoor outlet installed fine. A few days later went offline and refuses to connect. Sent back to Amazon and got a replacement. This one refuses to connect. Again a First Alert Z-Wave smoke detector works fine with this hub.
Anyone have any idea what is going on?
