I know firsthand just how difficult it is to work with all the disparate APIs for the different hardware providers, particularly with smartlocks. How do you deal with providing an ergonomic API on top of the access management and key/credential granting itself? Each of the APIs has different concepts, e.g. Salto's API has "binary keys", "zones", "access groups", "audit trails", etc...whereas SMARTair has "sites", "locking plans", etc. How do you deal with all of this? In other words, does your API abstract over all the APIs for purposes of setting up access? How would I, for example, given any type of lock, grant keys to a visitor which should expire in one week?
