I use the “Smart Lock Guest Access” SmartApp to manage guest codes on my smart locks.
For some reason, a couple of the Yale locks say they have “Code 251” under Lock Codes, but 251 is not an actual door code. Code 251 notifications are triggered when the master code is entered. There is no way to delete these false 251 Codes.
Anyone else encounter this / have a fix?
How long have you had these locks? Perhaps deleting the master code or a factory reset might help?
If you have access to rboy apps, use this custom DTH to address this issue (and more).
A “future proof” Universal Enhanced Z-Wave Lock driver
This driver is enhanced to fix bugs in the stock ST ZWave Lock driver, include patches for bugs in lock firmwares and bring out additional features for Schalge, Yale, Kwikset, IDLock, Popp, Samsung, Delaney, August Pro, Danalock, KeyWe, Philia, Vivint, Locstar etc zwave locks (see below for a full list of models and features). This works with all ZWave locks and newer ZWave Plus locks (see below for a list of locks tested).
It discovers/learns the lock features and automatically configures them. If a feature is not supported by the lock it will not show up or say Unsupported.
You need SmartThings Smart Lock Guest Access (SLGA), Advanced Web UI or a SmartApp like Lock User Management (LUM), Rental Lock Automater (RLA) to program user …
In general one should avoid using master codes to operate locks since it’s a security risk, you’re better off using user codes.
