I just moved over from wink yesterday there are a couple things I miss-can you add to smartthings ?
When a person is assigned a PIN it would be great if we could get an email when the pin is used to ie unlock the door. But only for people I choose.
There are two alternative options you can look into…
WebCoRE. It allows you to build complex rules and can be used in the situation you described.
And there is @RBoy apps that can also do this…
There is a built in SmartApp called guest lock codes. You can also you the built in automations to notify you when a lock is locked or unlocked
