You can also use your Smart Lock with the Nuki Smart Home skill for Alexa. Please note that Alexa makes a difference between two states: unlocking and locking. What matters is which door handle you've stored in the Nuki app. Depending on the door handle you've selected, Nuki also opens the door latch when unlocking it. If you've selected "Knob or bar" as the door handle, "unlocking" always automatically means "Open door" (Alexa can open doors with latch as well). If you've selected "lever", on the other hand, the door will just be unlocked without automatically opening it.
This also applies to Google Home and the Apple HomeKit.
