That is my plan. Their support is Mon-Fri working hours. I want to call their support and ask them if indeed z-wave is only usable if I register the lock, hook it up with their app and give up functionality of using it in standalone/offline mode. If they confirm there's no other way, I will return and buy something from a competitor instead.
