I’m in the process of debugging this issue myself but just wanted to know if anyone else has experience this problem. I think it may have something to do with the Smart Lighting SmartApp controls I’ve setup. While using the SmartThings app, if I inadvertently click multiple times on a StartThings Routine or a Device that is tied to multiple lights via the Smart Lighting SmartApp before it finishes, I can get the hub in a situation where the associated lights will flash on and off indefinitely until I restart the SmartThings hub. I was able to reproduce this problem on both the v1 and v2 hubs, of course I have to remove the batteries from the v2 hub to get it to reboot. If I was the only one using the app in my house, I wouldn’t be too concern. I worry if this happens while my wife uses the app and I’m not home.
Has anyone else experienced anything similar?
