Mainly because I was so used to my Iris system constantly having devices disconnected, how can I know if any of my devices aren’t talking to the hub?
I haven’t noticed any so I’m wondering if they really have never disconnected or I just don’t know how to tell? Is it possible to get an alert if something isn’t updating its status?
I wouldn't use Device watchdog. It has some bugs which the developer is still working out. Keep an eye out for when that is updated and then give it a try.
