Lock PIN first use notification

I am using Zwave locks for about 40 vacation rental properties. It would be really helpful if I could receive a notification when a door code is used the first time - effectively giving me notice of check-in. The built-in Vera notifications are kind of lacking.

Is there a plugin that will give me this capability?

i would think that Reactor would be able to check door lock operation and report pin used

Lock codes aren’t available, only slots (the positions where the code is used). If the code management system being used reuses slots (and it must, as there are few) you may not be able to discern the “first time” a code is used.
