I’ve added my Nuki 4 Pro as a Matter device on my Flic Hub so I can use a Flic Twist to open the door.
When I try to set up the action in the Flic app, it mentions a PINCode, is this something related to the KeyPad, if so is there a way to create them without a keypad?
I don’t know anything specific about Flic Twist, but there is an optional Matter feature called “require PIN code for remote operation”. If this is set, the Flic Twist needs to provide a PIN code within the Matter lock command in order to be able to lock/unlock/unbolt. Matter does not specify how this code is set or generated inside the lock.
Nuki does not support this feature, so you need to leave this empty.
Every lock command is recorded in the Activity Log of the Smart Lock. You can not see status commands, subscribe and other messages that Matter is sending.
