This morning I woke up to find several of my devices showing offline from Smartthings Motion Sensors, some of my Cree bulbs and Smartthings outlets. They show offline in both the ios app and in the IDE, yet they are all working properly in the app. Sensors are detecting motion, Cree bulbs and Smart plugs can be turned on and off with the app. I have never had this happen before in the three years I have had this system. Funny, though, is that the associated Smart Apps with these items will not work. Any ideas?
