Till we get an official release of the official lock code management by ST, here is a smartapp that you can use for multi-user setup:
The smartapps will help you setup up to 10 user codes based on my Custom Lock Device that I created for
my Yale locks (corrected some timeout issues).
I cannot guarantee that the code will work for all types of locks out there, but give it a try.
It works well in my environment.
Credit to bigpunk6 for the Custom Lock device that I modified for my own usage.
Merry Christmas to all!
If you like the smartapp(s), please support the developer.
