I have connected Lutron Caseta to Smartthings.
One thing I found is if I turned on the wall switches physically, Smartthings is not aware of the status right away. Sometimes the delay is 2-3 seconds, but more often it takes 10-20 mins or longer!!
It is a problem as I rely on the switch status for some of my automation routine.
The status in the Lutron app is always up to date. So it seems like it is only a Smartthings integration issue.
Has anyone run into similar problem? Any suggestion on how to fix it?
