I have this issue when the Yale lock hits the strike plate as it closes. It’s still physically locked and it will still accept a network command to unlock, but the lock is reporting a third status: “jammed,” which ST doesn’t know what to do with.
If this is the case, the activity log for the lock will likely show the “jammed” notification even though the tile doesn’t know how to display it.
This is one of those things that can get worse over time, or depending on the weather, or even vary depending on who is closing the door. I have one person who comes to my house and doesn’t shut the door all the way, and they cause this problem.
Yale is very aware that this can occur, their usual recommendation is just to widen the hole in the doorframe a bit so the bolt doesn’t hit the sides.
You will find this discussed in other Yale topics in the forum. Some people only have the problem when it’s been raining and the door slightly swells.
In all cases, widening the hole slightly is the usual solution.
