I have two original SmartThings Multipurpose sensors being used as garage door sensors. They’re being used by the Garage Door Monitor SmartApp on a Hub 1.0, and have been working flawlessly up until several days ago. Now, despite the fact that the doors are closed, and the Hub sees them as such, I’m getting a continuous stream of “open door” alerts.
Any ideas what went sideways, and how I can fix it?
