Nexx Home App - How to set up a voice pin code for Google Assistant
The newer "Nexx Smart Home" skill now requires a pin code for opening the door using voice commands (previously it was optional).
With the new updated skill, users will need to set the pin code under the Device Settings (tap the gear icon).
Go to the Works With screen in the Nexx Home app, and set the pin code under the Google Home field. Once done, tap the Save button at the top right.
