I installed a brand new Yale YRD240 lock today with z-wave module. Lock seemed to discover and add ok, but when I lock the lock, 4 out of 5 times, it doesn’t stay locked in smart things. Within seconds it switches back to unlocked (though the physical state is still locked). Conversely sometimes when the lock is unlocked it’ll report in ST as locked. There doesn’t seem to be a physical problem with the lock. It turns smoothly and the bolt seats properly. I’ve tested it with the door open so as not to obstruct the bolt in anyway and have the same issue.
Needless to say, a mis-reporting smart lock is about 50% useless.
This problem is apparently so prevalent that smartthings has a whole page about it, but their offered solution, of removing/re-adding the lock did nothing for me.
I’ve also tried Rboy’s advanced universal DH. Same problem.
I bought this lock because its on the supported list and so many people claim they’ve had success with it. Is there some issue with secure vs insecure inclusion? The ST page I mention above alludes to that but I can’t find where to configure it anywhere.
